Prepared Remarks:

Michael McGuire -- Senior Vice President, Investor Relations

Good morning, everyone, and thank you for standing by. Welcome to the conference call to discuss CVS Health's fourth-quarter 2018 results and 2019 outlook. As a reminder, this call is being recorded on Wednesday, February 20th, 2019. I'm Mike McGuire, Senior Vice President of Investor Relations for CVS Health. I'm joined this morning by Larry Merlo, President and CEO, and Eva Boratto, Executive Vice President and CFO. Following our prepared remarks, we'll host a question and answer session. In order to provide more people with the chance to ask their questions during the Q&A, please limit yourself to no more than one question with a quick follow-up.

In addition to this call and our press release, we have posted a slide presentation on our website that summarizes the information in our prepared remarks as well as some additional facts and figures regarding our operating performance and guidance. Our 10-K will be filed later this month, and that, too, will be available on our website once filed.

I have one announcement this morning. Our annual Investor Day has been scheduled for Tuesday, June 4th in New York City. You'll have the opportunity to hear from our senior management team, who will provide a comprehensive update on the execution of our strategic vision and an in-depth review of our strategies for driving long-term growth and creating shareholder value. We plan to send invitations via email with more specific details in the spring, but please save the date. Again, that's Tuesday, June 4th.

Please note that during this call, we will make certain forward-looking statements that reflect our current views related to our future financial performance, future events, and industry and market conditions, and forward-looking statements related to the integration of the Aetna acquisition, including the expected consumer benefits, financial projections, and synergies. These forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from what may be indicated in the forward-looking statements. We strongly encourage you to review the information in the reports we file with the SEC regarding these specific risks and uncertainties, in particular, those that are described in the Risk Factors section of our annual report on Form 10-K and the cautionary statement disclosures in our quarterly report on Form 10-Q. You should also review the section entitled "Forward-Looking Statements" in our earnings press release.

During this call, we will use non-GAAP financial measures when talking about our company's performance and financial condition. In accordance with SEC regulations, you can find a discussion of these non-GAAP measures and the comparable GAAP measures in the associated reconciliation document we posted on the Investor Relations portion of our website. And, as always, today's call is being webcast on our website, where it will be archived for one year following today's call. Now, I'll turn this over to Larry Merlo.

Larry Merlo -- President and Chief Executive Officer

Thanks, Mike. Good morning, everyone, and thanks for joining us today. We achieved strong performance in the fourth quarter and in full-year 2018, and importantly, with the completion of our merger with Aetna, we have positioned CVS Health to excel in a market that is undergoing profound and rapid transformation.

In recent years, it has become increasingly evident that the path to long-term growth and value creation lies in the establishment of new, integrated healthcare models that provide consumers better care and convenience at a lower cost. And, since closing the Aetna merger, we are increasingly confident in the synergistic potential of this powerful combination to build and deliver shareholder value.

CVS Health is in a superior position to lead the change needed in the fragmented U.S. healthcare system with our compelling, fully integrated healthcare offerings, our unmatched local community assets, proven pharmacy care leadership, and a commitment to collaborating with healthcare providers to achieve the very best outcomes for the patients and clients we serve.

In 2018, we delivered on our financial expectations, as did Aetna, laying a strong foundation for a successful combination. We generated significant cash flows, with nearly $7 billion of free cash for full-year '18, consistent with our expectations, and we returned $2 billion back to shareholders through dividends, and later deployed the cash we raised in early '18 to fund the Aetna merger. So, in short, 2018 was a milestone year, both tactically and strategically, as we successfully completed our transformational merger with Aetna.

Now, we also delivered on key foundational steps for growth in healthcare services. This includes making more than 80% of primary care services available to consumers at MinuteClinic while also increasing home visits by Coram for infusion services by more than 15%. Importantly, we began effective implementation of our integration strategy and took important steps toward building the integrated healthcare model that will bring substantial value to our various stakeholders.

Now, we expect 2019 to be a year of transition as we integrate Aetna and focus on key pillars of our growth strategy, creating a more consumer-centric healthcare experience. As an example, our first three concept stores were unveiled earlier this month, and you probably saw press coverage last week, and there's a lot of excitement around the consumer engagement and response. Now, it's still early, as we're in the learning phase and working to define a hub-and-spoke approach, but it's an example of the work under way, and I'll share additional progress on achieving our vision in just a few minutes.

Now, that said, we're also fully aware of the need to address the impact of certain headwinds that are having a disproportionate impact in '19 when compared to prior years. Many of these issues we've talked about previously, and most significant is the ongoing pharmacy reimbursement pressures in our businesses and the reduction in offsets to those pressures. What we're experiencing in '19 is a declining benefit from new generics, lower brand inflation and the ongoing questions around rebates, along with some structural and CVS-specific challenges in the long-term care space. And, while these factors will negatively affect the business in the short term, I want to outline the comprehensive actions we have taken in response.

In our Retail business, we are continuing to develop product and service initiatives that will accelerate top-line revenue and profitability. We are winning from a growth perspective, and we expect to continue on those positive trends. In the front store, this includes introducing new product lines in the health and beauty areas along with the expansion of higher-margin service offerings.

In the pharmacy, we will continue to deliver market-leading top-line growth through our network relationships and clinical care programs. Additionally, we are developing a new retail contracting strategy that better aligns reimbursement to the value our clinical products provide, enabling adherence improvements and star enhancements while saving patients money, to name just a few.

Second, in the PBM, we've created a new contracting model that provides for more transparency, simplicity for, and alignment with our clients. The Guaranteed Net Cost pricing model is an innovative way to approach the market by allowing us to maximize all cost-control tools at our disposal. In this model, clients will receive 100% of rebates while we leverage our core strengths of contracting expertise and utilization management to drive lower net costs for clients and members without compromising on the quality of care.

Now, this is a win-win. Clients will benefit from the simplicity of one guaranteed price per claim that's focused on lower net costs and not discounts and rebates. Now, we've introduced this approach to clients and benefit consultants, and we will have a small number of clients adopting the model this year. We expect a more rapid adoption in '20 and beyond.

Third, back in August, we outlined a four-point plan to get the Long-Term Care business back on track, and while progress is being made in the identified areas, the benefits are being offset by the external factors impacting the skilled nursing business, and work is under way to accelerate the action plan timeline to achieve the benefits more quickly, and we've already begun to see some progress, realizing nearly $80 million in process improvement savings, with more to come.

Fourth, in early January, we began planning a new cost reduction effort across the enterprise, going beyond the previously announced productivity initiatives of the legacy companies and targeting opportunities that neither company would be able to accomplish as a stand-alone. This effort is in addition to the near-term synergy work tied to the $750 million target, which we are on track to exceed. As we look across the new combined enterprise, there are significant streamlining opportunities in member enrollment, claims processing, and customer service, as well as through the use of robotics and advanced analytics. Additionally, we are focused on aggressively managing working capital, especially through the reduction of inventory and improvement of terms within our payables, and we'll have more details for you on our May earnings call.

Finally, we continue to evaluate our assets and the roles they play in enabling the core strategies of our new company. So, we'll provide updates to the actions we have under way as we execute our vision in a strategic and innovative, yet practical, realistic, and carefully prioritized way. We understand acutely the importance of balancing near-term execution with longer-term vision, and we are confident that these actions will position us well in 2020 and beyond.

Now, several key pillars that we are executing on today will drive above-market growth going forward in this rapidly changing healthcare environment, and a few key initiatives that underlie the ongoing execution of our strategy are as follows. First, we are growing membership. We are working to expand the reach of our government business, with Medicare positioned to lead the way. Medicare Advantage top-line growth is being driven by the addition of new membership in existing markets and continued geographic expansion.

Driving excellence in star ratings continues to be a primary focus for our business, and by enhancing our clinical model, products, and capabilities, we are expanding our offering to take care of higher-acuity and complex members, including dual-eligibles, a critically important set of beneficiaries, when bending the cost curve. Our success in building the largest Medicare Part D plan, SilverScript, while simultaneously becoming the partner of choice for more than 40 health plan Part D clients gives us the confidence that we can further expand upon the success of both organizations.

Looking ahead, we see a strong and growing pipeline of new business opportunity within group Medicare for 2020, and we see opportunity as well within Medicaid, building upon the success we've had with recent wins in Kansas and Florida. And of course, we are actively working to strengthen our commercial offerings.

Now, success in all of these areas requires the use of our full breadth of capabilities -- comprehensive data, predictive analytics, and our unparalleled intervention points with consumers -- to drive behavior change and improve health outcomes, and both Aetna and CVS Caremark have very successful employer businesses, and we're working on opportunities to create new products and services to meet the needs of these payers.

Second, we're creating differentiated products and services at the community level, driving meaningful value for both consumers and payers while improving the bottom line. Now, this reflects our broad base of consumer-facing assets that is highlighted by our nearly 10,000 CVS pharmacies, and I touched on the first concept stores earlier, but importantly, our assets extend well beyond our pharmacies when you think about the role and the value that MinuteClinic, Coram, Accordant, and other ancillary businesses can play. And, while our community assets have the power to improve outcomes and reduce costs, they also contribute to enterprise revenue and earnings growth.

Third is the role of partnerships in accelerating innovation, and our recent announcement with Apple on the development and springtime rollout of Attain by Aetna is just one example. Applying new technologies will be a component of our consumer-centric approach to improving health.

Finally, we are establishing the optimal structure and go-to-market strategy for our health services offerings. We've been very clear about our vision of creating an open-platform model that will serve the needs of all payers, and to support this goal, we are integrating existing capabilities with new products and services that will benefit all Aetna and Caremark clients and their members, and we are on track to have this in market for the 2021 selling season.

So, we're more excited than ever about our progress and the opportunities that lie ahead. We also have a good understanding of the factors that impact our business in the near term and are actively working to address them. We view 2019 as a bridge to the future, and we expect our businesses to strengthen meaningfully from the integration of CVS and Aetna's core capabilities.

Now, I'm also pleased to introduce the leaders of our businesses: John Roberts, Chief Operating Officer, Kevin Hourican, President of CVS Pharmacy, Karen Lynch, President of Aetna, and Derica Rice, President of CVS Caremark. They'll be joining us for the Q&A after our prepared remarks, and our senior leadership team is energized by the prospects of our new company, and together with all of our colleagues across the enterprise, we are laser focused and fully committed to delivering on the vast potential of this combination. So, let me turn the call over to Eva to walk through key items from '18 and the details of our '19 financial outlook.

Eva Boratto -- Executive Vice President and Chief Financial Officer

Thanks, Larry, and good morning, everyone. Before I get into the details of our results and guidance, please note there is a significant amount of information in the presentation we posted to our website this morning to help you understand the changes to our financials for both 2018 and 2019. Regarding 2018, while the face of the P&L is different, definitions of non-GAAP are consistent with legacy CVS. However, interest income is shifting from net interest expense to revenues to conform to insurance company presentation. With that, I'll provide some key highlights for 2018.

As Larry stated, CVS Health generated significant free cash of nearly $7 billion for the full year '18, and we used it in addition to the cash on hand to repay $5.5 billion in debt, of which $3.5 billion were scheduled maturities and $2 billion was a voluntary early repayment of a five-year term loan. We also delivered $2 billion to shareholders through our dividend.

We delivered adjusted EPS of $7.08, at the high end of our guidance range, reflecting the addition of Aetna, with all of our businesses performing at our expectations. On a stand-alone, CVS Health adjusted revenue grew 2.3% in 2018, at the top end of our full-year guidance range. With the addition of 34 days of Aetna's operations, which are now embedded in our new Healthcare Benefits segment, adjusted revenues grew 5% to $194 billion, with HCB contributing an additional $5.1 billion after considering eliminations.

In 2018, the Retail/Long-Term Care segment delivered adjusted script growth of 8.8%, driven by our pharmacy clinical programs, comprised of increased adoption of 90-day programs as well as the successful partnering with PBNs and health plans via network relationships, including additional preferred positions in a number of Med D networks.

Adjusted operating income declined by 1.2%, driven by our decision to invest a portion of the benefits we realized from tax reform into wages and benefits. Additionally, we continue to experience underperformance in the Long-Term Care pharmacy business. Excluding those two items, stand-alone Retail Pharmacy adjusted operating income grew solidly by about 5% over full-year 2017. Notably, our market-leading script growth increased our pharmacy market share to a record 26% in December.

In the PBM, adjusted claims increased 6.1% over full-year 2017, driven by net new business wins and continued adoption of Maintenance Choice. PBM operating income was up nearly 1%, as expected. The formulary and cost management strategies Caremark has developed effectively mitigated drug cost increases in 2018. Prices for non-specialty medications decreased 4.2% for commercial clients, while we also held price growth on specialty products to just 1.7% despite even higher list price increases. We also worked to improve health outcomes and reduce member cost, successfully driving the average cost per script for plan members down for a third year in a row.

And finally, the Healthcare Benefits medical membership was 22.1 million. Government programs represented approximately half of HCB's insured membership at year-end '18, positioning the segment to drive future growth. Overall, HCB operations performed as we expected. Medicare Advantage membership growth materially outpaced the market, fueled in part by our strong stars performance. Our clinical care and service programs expanded their reach in 2018, resonating in the marketplace and strengthening the value proposition of our commercial offerings.

Adjusted gross margin for legacy CVS Health was 15.6%, up 20 basis points compared to full-year 2017. This was due to mix, given that the higher-margin Retail business grew faster than the PBM. Total adjusted operating expense dollars increased 12%, largely driven by the addition of Aetna's business as well as investments from a portion of the tax reform benefits into the retail business and cost to support pharmacy growth. As noted in our press release this morning, due to continued industrywide and operational challenges, in Q4, we recorded a $2.2 billion goodwill impairment charge on the Long-Term Care business.

Transitioning to our 2019 guidance, there are a few key changes to note. Beginning in '19, we are realigning our segments for changes to our operating model that I'll detail shortly, and our adjusted operating income guidance reflects the adoption of Aetna's legacy definition, which excludes intangible amortization. We maintain the same definition for adjusted EPS, which excludes intangible amortization and transaction and integration costs, which were consistent across both companies. A summary of the changes is included in the slides we posted to our website, along with the full GAAP to non-GAAP reconciliation. 2018 has been adjusted for comparability as appropriate.

As stated in our press release, consolidated full-year adjusted EPS is expected to be in the range of $6.68-6.88, down from the $7.08 we reported in 2018. We expect consolidated full-year 2019 adjusted operating income between $14.8-15.2 billion, with consolidated revenue in the range of $249.9-254.3 billion. For the segments, we expect operating income in the Retail/Long-Term Care segment to be in the range of $6.6-6.7 billion and Pharmacy Services segment in the range of $4.8-4.9 billion. We expect the HCB segment operating income to be in the range of $5.1-5.2 billion.

Significant synergies will be generated by the combined business this year, stemming from elimination of duplicative corporate and operational functions, purchasing efficiencies, and some medical cost savings, including formulary alignment. These synergies are expected to be between $300-350 million in 2019, and we are on track to exceed our goal of $750 million in 2020.

Additionally, there will be investments and initiatives designed to set the foundation for future new product offerings. Investments are being made to further our analytics and digital capabilities, develop new programs, such as chronic kidney care, and enhance Aetna's clinical platform. We expect our incremental investment spending to be between $325-350 million in 2019. Integration costs of approximately $550 million are excluded from our non-GAAP guidance. We expect to deliver between $9.8-10.3 billion of cash flow from operations.

We remain committed to our capital allocation priorities. After the payment of our shareholder dividend, capital retention to support our insurance operations, and gross capital expenditures of $2.3-2.6 billion, we will use the remaining cash available to continue to pay down debt. As we stated when we announced the Aetna acquisition, while we intend to maintain our shareholder dividend, we will not restart share repurchases or engage in large M&A transactions until we achieve our leverage targets. We expect to pay down our maturities this year as they come due, and have other sources of pre-payable debt available to us. We expect leverage to modestly improve, and we will pay down debt in line with previous expectations.

Moving on to the segments, for the year, we expect Retail/Long-Term Care revenue to be between $85.3-86.8 billion, with adjusted operating income down about 10%. Retail is expected to continue to deliver strong adjusted script growth in the range of 4.5-6.8% due to continued successful execution of our pharmacy clinical care programs that drive improved adherence and patient retention. Additionally, we will experience growth in the Medicare partnerships we formed in 2018, as well as a few new regional preferred relationships in 2019. The contraction in adjusted operating income reflects the annualization of tax reform investments and expected performance of long-term care. These factors are expected to contribute nearly half of the contraction.

Continued reimbursement pressure without the full benefits of traditional offsets is also causing contraction. Historically, reimbursement pressure has been primarily offset by growth in generics as well as inflation on branded pharmaceuticals. We will experience a larger year-over-year headwind from a lower contribution from break-open generics and a diminished return on generic dispensing increases. The front of the store is expected to drive margin, with a focus on winning in our health and beauty businesses through improved customer personalization and consumer engagement. Front-store margin rate and dollars are expected to expand year over year.

As we look to the future, we believe CVS Retail is best positioned in the market to deal with the challenges we see. Our best-in-class clinical programs will allow us to continue to gain market share. We have strong partnerships with payers, including incentives to drive dispensing into our CVS channel, and finally, we will continue to drive efficiencies in our pharmacies through the use of technology and productivity improvement.

Now, let me turn to the PBM. This segment's 2019 reported figures will be affected by two important reporting changes. First, our individual SilverScript PDP will move from the PBM segment to the Healthcare Benefits segment, enabling us to rapidly create the best products for seniors in advance of the 2020 bid season in this important part of our business. We have restated 2018 results for comparability, and this information is also available on our website. Second, we will consolidate the pharmacy operations of Aetna into the PBM to enable us to rapidly drive efficiencies.

For the PBM segment in 2019, we expect revenue to be in the range of $136.5-139 billion, with adjusted operating in come down low single digits. There are a few key elements driving 2019 PBM performance to note. As we have stated previously, price compression continues to be a factor in the marketplace. Exacerbating the impact is the cumulative effect on rebate guarantees due to lower branded inflation. Second, the net benefits from the 2019 selling season are expected to be modest, and we expect Anthem to remain as strong a headwind given the investments required to onboard the business on its accelerated timeline. The onboarding is expected to begin in the second quarter of this year. As a reminder, the revenue for this contract will be recorded on a net basis.

Our retention rate stands at a strong 98% for 2019. In addition, Centene has notified us of their intent to move their business to their PBM partner, RxAdvance. It is expected to begin in 2019, although the exact timing is not clear at this point. The retention rate I mentioned excludes any impact from this transition.

Additionally, the PBM will benefit from the segment shifts. On a like-for-like basis, operating income will be down mid-single digits versus 2018. It is clear that the PBM industry is in the middle of an environmental change, given the dialogue around rebates. However, it is also clear that the PBM brings tremendous savings and value to the clients we serve. The importance of size, scale, and customer relationships will continue to be paramount, and we remain focused on delivering the value our clients expect.

Finally, in the Healthcare Benefits segment, we expect revenue between $67.7-68.7 billion in 2019. We expect continued strength in our government programs, with top-line increases driven by industry-leading Medicare growth as well as the key Medicaid wins in Kansas and Florida. We expect to end the year between 22.7-23 million medical members, as we expect strong commercial ASC membership gains to complement our government program growth.

A handful of other dynamics will impact HCB results, including: Year one deal synergies will disproportionately benefit the HCB segment. Second, incremental investments will be deployed in 2019 to accelerate growth, enhance infrastructure, and drive market differentiation. Third, the suspension of the health insurer fee in 2019 will impact certain operating ratios, while the after-tax impact of this suspension versus 2018 is immaterial. And finally, certain one-time benefits realized by Aetna in 2018 are not expected to repeat in 2019, and the HCB segment will be negatively affected by the segment movements discussed earlier. Excluding the segment moves, the incremental investments we're making in 2019 to accelerate growth and the impact of the HIF suspension, HCB operating income is expected to grow modestly.

Turning to operating efficiencies, both CVS and Aetna have had a strong history of successful cost productivity initiatives, and as we begin integrating the two companies, we are seeing the opportunity to accelerate our cost savings across the enterprise even further than originally expected. As Larry stated, we are embarking upon an aggressive cost reduction initiative. The savings this will generate will help offset the competitive dynamics we have experienced, drive the creation of more affordable products for our customers, and provide capacity that will help us achieve our financial targets as we continue to invest in our strategic and transformational initiatives. We are confident that these initiatives will help drive longer-term growth in the combined business beyond 2019.

Before I wrap up, I want to touch on expectations for the first quarter and the remainder of the year. In Q1, we expect to deliver adjusted EPS of $1.49-1.53 and GAAP EPS of $1.04-1.08. As you look at the spreads for the remainder of the year, you can assume that the seasonality of our expected results this year will closely resemble that of our reported results in 2018. Year-over-year growth of consolidated adjusted operating income will be highest through the first three quarters as we wrap the addition of Aetna. In the legacy CVS business, Retail/Long-Term Care, and PBM, we expect to see our greatest level of year-over-year deterioration in Q1, with operating income growth in those segments improving as we move throughout the year. Adjusted operating income within HCB is expected to be greatest in Q1 and lowest in Q4.

At our Investor Day in June, we will provide you a more detailed roadmap to long-term growth. We will provide you with our long-term targets, including more specifics around the innovative products and services we plan to bring to market. We'll also lay out our capital structure and allocation plan to provide you with more visibility into the timeline for returning more capital to shareholders, while also continuing to invest in the business. With that, I'll turn the call back to Larry.

Larry Merlo -- President and Chief Executive Officer

All right. Thanks, Eva. Well, CVS is much better positioned to provide value to our customers and the broader community through our new enterprise model, and our diversified company is providing our stakeholders with a highly effective ability to make healthcare more local, more simple, and less costly while reducing our dependencies on dispensing revenue and maximizing the benefits from value-added services. We have a number of unique offerings being piloted or launched in the coming months, and those capabilities utilize enterprise assets in a differentiated way, with the goal of increasing consumer engagement while improving health outcomes and lowering costs. As an example, expanding MinuteClinic services and incorporating CVS community assets in conjunction with Aetna analytics around a member's next best action will allow us to help individuals achieve a better health outcome.

And, we see tremendous opportunities ahead, whether it's improving adherence, closing gaps in care, engaging high-risk members through care managers, or providing new approaches to complex disease management. Just take the mitigation of hospital readmissions. We understand the contributing factors to readmission, and we can now bring solutions to those factors. Aetna had about 470,000 hospital discharges in 2017, and about 47,000 of those were readmitted, at an average cost of $14,000.00. If we're successful cutting that number in half, we remove more than $300 million of costs while creating a better patient experience. Again, the list of opportunities goes well beyond the few examples mentioned.

Importantly, many of these unique service offerings will ultimately be available to our health plan clients, creating value across the healthcare system, and it's this combination of assets and capabilities that will ultimately drive enterprise growth and create significant shareholder value. So, with that, let's go ahead and open it up for your questions.

Questions and Answers:

Operator

In order to ask a question over the phone, please press *1 on your telephone keypad. Our first question comes from Michael Cherny from Bank of America Merrill Lynch. Please go ahead.

Michael Cherny -- Bank of America Merrill Lynch -- Analyst

Good morning, and thanks for all the details so far. Larry, Eva, if we think about all the headwinds in particular that you outlined going back to your conference presentation last month, relative to then, what was it that you expected, and most importantly, as you think about all of the big ones -- whether it's Omnicare, Anthem, Centene transition, et cetera -- what do you think is the most transitory? In particular, what do you have the most confidence in that are transitory that will be able to reverse itself, or at least improve, in '20 and beyond?

Larry Merlo -- President and Chief Executive Officer

Mike, it's Larry. Good morning. Thanks for the question. Mike, as you look at the transitory nature of the headwinds, you think about the impact of the investments and tax reform -- that rolls off midyear this year. You look at the inflation impact on our rebate guarantees -- that peaks in 2019 and rolls off at the end of 2020. We certainly expect the Omnicare performance to stabilize and improve. And, as you think about the contribution of generics, as we've talked many times, there are going to be peaks and valleys that can occur in any given year.

As we sit here today and look at what that looks like for 2020, we expect that to improve. So, many of these headwinds are transitory in nature, and also, keep in mind that there are parts of the business that have momentum -- growth in Medicare, growth in the commercial business. We've got momentum in Retail, not just in front-store growth, but pharmacy growth as well, and we're really pleased with the speed with which we're executing the integration activities.

Eva Boratto -- Executive Vice President and Chief Financial Officer

And, Larry, the only thing that I would add there -- as Larry outlined, we also see additional opportunities to continue to manage our cost base and reduce our core to help mitigate these headwinds as we go forward.

Michael Cherny -- Bank of America Merrill Lynch -- Analyst

Thank you.

Operator

Our next question comes from Lisa Gill from J.P. Morgan. Please go ahead.

Lisa Gill -- J.P. Morgan -- Managing Director

Thanks very much. Good morning, everyone. Let me just first go back to the guidance again. Looking at the different segments versus our numbers in the Street, it looks like the biggest headwind year over year is clearly on the Retail side. Larry, when you talked about things that were transitory -- obviously, Omnicare being one of them -- is that the biggest driver within Retail? You talked about a new type of model around reimbursements. Is that something you believe will take hold in 2020 and reimbursement will start looking better? I just really want to understand how we think about how retail really turns around -- that would be the first part of my question. Secondly, how do we think about that $3 billion cost-cutting initiative that you talked about a couple of years ago? Where do we see that in the numbers and how is that coming along?

Eva Boratto -- Executive Vice President and Chief Financial Officer

Hi, Lisa. This is Eva. I'll start. As you think about the performance in Retail contracting about 10%, the impact of Omnicare as well as the tax reform investment -- that represents about half of the contraction, and clearly, the next most significant driver is what Larry described around lower benefit from generics in 2019. In terms of the streamlining efforts, that is on track, and we're delivering in line with our expectations. It's reflected in both the PBM and the Retail segments.

Kevin Hourican -- Executive Vice President, CVS Health and President, CVS Pharmacy

Good morning, Lisa. This is Kevin. I can also talk about the longer-term component. Our plan to improve profit outlook in Retail is focused on three very important things. First is to grow the top line. Increasing script volumes enables us to leverage the highly fixed-cost nature of retail pharmacy fulfillment. That's the first. The second is to lower our fixed and variable costs. As Eva just spoke through, there's significant productivity improvement, namely automation within the pharmacy fulfillment progress as well as continued reduction in cost of goods sold through Red Oak. The third -- and, Larry mentioned this in his prepared remarks -- is the migration to a new and improved third-party payer contracting model. We will align incentives with payers to lower overall healthcare costs and begin to reduce the pressure over time on the actual core pharmacy reimbursement rate.

Lisa Gill -- J.P. Morgan -- Managing Director

And then, just as a follow-up to that, is Omnicare strategic to the company going forward? As I listen to you, Omnicare has been a headwind last year; Eva, you just talked about it being half of the headwind for 2019. Is this a strategic asset for CVS going forward?

Larry Merlo -- President and Chief Executive Officer

Lisa, it's Larry. The growth opportunity with Omnicare was always focused on the independent and assisted living spaces, and those opportunities still exist, and they're consistent with our strategy of putting the customer at the nucleus of transforming care. The challenges that we have in that business are really around the skilled nursing facilities, which have been worse than we originally expected.

Lisa Gill -- J.P. Morgan -- Managing Director

Okay, thank you.

Larry Merlo -- President and Chief Executive Officer

Thanks, Lisa.

Our next question comes from Ralph Giacobbe from Citi. Please go ahead.

Ralph Giacobbe -- Citigroup -- Analyst

Thanks. Good morning. Just going back, I was hoping -- and, I can certainly understand the directional commentary, but are you guys willing to actually sort of quantify the drag in each of the buckets as you laid out the headwinds and just give us more clarity on the numbers and size of each of the drags?

Eva Boratto -- Executive Vice President and Chief Financial Officer

Ralph, this is Eva. In terms of -- I tried to quantify pieces of it. As you look at Retail, which has the most significant impact, the impact of Omnicare as well as the annualized impact of the tax reform investment is driving nearly half of the contraction on the Retail business, and think about the remainder -- clearly, the lack of generics -- as the biggest driver there. Certainly, on the PBM side, the impact of the cumulative nature of the rebate guarantees affected by the lower inflation is a pretty significant driver on the PBM business. Additionally, we said it'll peak in '19. We had some impact in '18. It's what moves -- it was a key element moving us to the lower end of our guidance range. And, we do expect that to move through 2020.

Ralph Giacobbe -- Citigroup -- Analyst

Okay, all right. That's helpful. And then, just maybe a quick follow-up -- you've had a little more time to digest the HHS rebate proposal. Any updated thoughts there, particularly if it gets implemented for 1/1/20? And then, more broadly, you mentioned the new PBM net pricing model. I think you expect to see a small number initially and more rapid adoption beyond 2020. How do you drive that change, particularly if employers like the legacy model, and do you see yourselves moving perhaps to just that net pricing model and perhaps moving away from rebates altogether? Thanks.

Larry Merlo -- President and Chief Executive Officer

Ralph, it's Larry. I'll take the first part and then flip it over to Derica to talk about the new pricing model. As you look at the rebate role, we fully support the administration's objective to lower drug prices and out-of-pocket costs for consumers, and CVS has pioneered a number of innovative solutions that have delivered against that goal. Unfortunately, we see the rebate role taking us backwards, not forwards, and we've been very public about the fact that 100% of rebates are turned over in the Medicare business and have been utilized to buy down premiums. You look at that dynamic -- premiums will increase, and some actuarial reports have it growing as much as 52%.

We actually took a step back and looked at today's Part D program. We went back to 2009, we looked at monthly premiums -- 10 years ago, they were $29.00. Ten years later, they're $32.00. At the same time, you look at generics -- they represent about 90% of all Part D scripts that are dispensed. So, those are two important data points that absolutely point to premiums increasing for everyone, and the reality that yes, a small percentage of seniors may net out favorably, but again, the actuaries are estimating as many as 70% of beneficiaries are going to be worse off. So, one of the concerns that we have is that will fewer beneficiaries sign up for Part D? And then, you look at the estimated cost -- $200 billion over 10 years -- it puts taxpayers on the hook, and branded pharma ends up with a profit windfall.

There are certainly readily available solutions in the commercial space that can be applied to Medicare, and you look at what those potentially could be -- we work with commercial clients today to reduce out-of-pocket costs with point-of-sale rebates and the utilization of a preventive drug list. We think programs like that are far better solutions than the proposed role, and we also have -- we've talked about the real-time benefits toll in Caremark. Kevin's got a similar program in our retail pharmacies, and both of those tolls have reduced out-of-pocket costs for consumers. So, we're certainly weighing in during the comment period with our concerns with the rebate role, but more importantly, what we believe the appropriate solutions are to address the root cause of what we're trying to solve for. Derica?

Derica Rice -- Executive Vice President, CVS Health and President, CVS Caremark

Good morning, Ralph. This is Derica. In regards to our new pricing model, which we're calling the Guaranteed Net Cost model, we've had two clients who adopted for 2019. In addition to that, we've already provided to all of the benefit consultants draft contract language, so they've been able to walk through and see all of the elements in terms of the fine print and the details. The feedback thus far has been very positive, so we will look to continue to drive a more rapid adoption through the remainder of '19, and more specifically, for the 2020 period.

In terms of rebates, whether we have rebates or discounts, what we really want is still the opportunity -- and, this is kind of piggybacking on the HHS rule question -- our ability to execute formulary management, which is the methodology we've been able -- the tool we've been able to use historically to be able to create rebates and discounts from manufacturers to create value for our clients and their members. So, as long as we have access to that wherewithal to be able to do that with the manufacturers, we'll be able to execute the GNC model, and really, what this means is getting to the lowest net cost, and it's not a focus on aggregate rebate value.

Eva Boratto -- Executive Vice President and Chief Financial Officer

Our next question comes from Justin Lake from Wolfe Research. Please go ahead.

Justin Lake -- Wolfe Research -- Managing Director

Thanks, good morning. I first wanted to discuss rebate guarantees and the break-over generics. I'm just trying to understand them into 2020. So, it sounded like, Larry, you said break-over generics get better in 2020 versus 2019. Give us any order of magnitude there, and then, same thing on rebate guarantees. It sounds like it peaks in 2019. Does it get better in 2020 in your mind? Maybe you could tell us about some of the remediation that you've assumed in your guidance around rebate guarantees.

Jonathan Roberts -- Executive Vice President and Chief Operating Officer, CVS Health

Justin, this is John. I'll take the generic question first. So, the overall dollar amount of generic launches in '19 is similar to what we saw in '18, but there's some key differences. So, you heard us talk about less value from break-open generics in '19 compared to '18, and that's primarily due to the timing of the launches leading to slower progress in '19 to the break-open status. But, there are also more generics launching in '19 compared to '18 that are single-source generics, where we're unable to optimize our profitability during that exclusivity period, and as a result, these generics, for the most part, are headwinds in '19.

And finally, in '19, we're seeing generics that launch with limited competition, stay with limited competition even after the exclusivity period expires, and this is driven by many factors, including manufacturing complexity and regulatory approval timelines. But, as we look forward into 2020, based on what we know today, we see 2020 improving from where we were in '19.

Derica Rice -- Executive Vice President, CVS Health and President, CVS Caremark

And, Justin, this is Derica. In regards to the rebate guarantees and exposure, just recall from both Eva and Larry's remarks that we anticipate that the rebate exposure peaks in 2019, and we anticipate that it will dissipate over the '20 and 2021 period. And, we've also been able to go back and adjust our underwriting models to now, we're assuming a mid-single-digit inflation rate...so, much more in line with current trends.

Justin Lake -- Wolfe Research -- Managing Director

If I could just sneak in a follow-up, the last number you gave us on rebates retention was $300 million, I believe, and that's net of payouts for rebate guarantees. Given that rebate guarantee payouts have gone up, can you give us an updated number there.

Eva Boratto -- Executive Vice President and Chief Financial Officer

Justin, this is Eva. That was a stand-alone legacy CVS PBM, and I would say it's in the same ZIP code, if you will, in terms of that overall two to three percentage points.

Justin Lake -- Wolfe Research -- Managing Director

Thanks.

Our next question comes from Ana Gupte from SVB Leerink. Please go ahead.

Ana Gupte, Ph.D. -- SVB Leerink -- Managing Director

Hey, thank you. Good morning. My question was about on the health benefit side -- the medical loss ratio -- you had said that the experience-rated book would create a reset. It's a bit more than we had anticipated. I wanted to know if this is a one-time thing, and can you talk about -- on the commercial side -- what the implications were there for membership on either retention and/or new growth? Also, when you're planning to go to market with that and the Caremark book together. Is it going to midyear this year, in '20, or maybe later?

Eva Boratto -- Executive Vice President and Chief Financial Officer

Ana, this is Eva. I'll start. As you look at our guidance for the MBR of about 84%, there are a couple things that I would call out. First, obviously, the mechanics of the HIF, as well as if you look at the mix of our business, we have very material growth in the government services business, which obviously also increases that MBR. And, it's early in the year, and we feel it's important to be prudent as we look at these estimates.

Karen Lynch -- Executive Vice President, CVS Health and President, Aetna Business Unit

Ana, just to answer your question on when we go to market with Caremark book, obviously, we're in the process of evaluating where we have opportunities. We are rapidly looking at where we have medical and non-pharmacy and vice versa, working very closely with Derica. We're building products and service capabilities so that we can go to market. You should expect us to go to market later this year, early in '20.

Ana Gupte, Ph.D. -- SVB Leerink -- Managing Director

If I could just sneak in a follow-up on that, also, on the tax reform, Aetna had seen some pressure on MLR rebates. Will this combination help you on that? Might that start in 2020? I think you had also talked about enterprise value in your last communications post-close, and is that going to impact how you price your Aetna book? Because you do have value that's created now from the PBM and retail that wasn't there earlier/

Karen Lynch -- Executive Vice President, CVS Health and President, Aetna Business Unit

Yeah, relative to pricing, we will factor all that and consider that in our pricing, but Ana, what I would tell you is we'll continue to maintain pricing discipline on our commercial book, but we'll take the value of a combined organization or the value that we expect to capture from additional services in consideration when we do price our book.

Ana Gupte, Ph.D. -- SVB Leerink -- Managing Director

Great. Thanks, Eva. Thanks, Karen.

Larry Merlo -- President and Chief Executive Officer

Our next question comes from Steven Valiquette from Barclays. Please go ahead.

Steven Valiquette -- Barclays -- Managing Director

Great, thanks. Good morning, everybody. So, for the HCB segment, the slides include that comment that excluding segment shift impacts, incremental investments, and the impact of the HIF, the operating income is expected to grow modestly over 2018. I think some investors might have been expecting that profit growth to be a little bit stronger in '19, just given the robust Medicare Advantage membership growth for Aetna -- actually, for both last year and this year. There's a general notion that new MA lives aren't that profitable in year one, but maybe you can just give us a little more color at a high level around the Medicare Advantage membership growth in 2019, maybe just frame it in terms of top-line growth versus profit growth within HCB. Thanks.

Eva Boratto -- Executive Vice President and Chief Financial Officer

Steve, this is Eva. I think a key aspect is we noted in our prepared remarks that we're making significant investments in terms of transformation. There's some of that affecting the HCB segment, so the modest growth is obviously taking into account that impact.

Karen Lynch -- Executive Vice President, CVS Health and President, Aetna Business Unit

Let me just comment on general Medicare growth in '19 and '20 -- both years. We are above industry growth. You have to consider when you look at our Medicare business to split the mix between individual and group. Obviously, there are different margin profiles on those books. If you think about 2020, we are exceptionally pleased with the growth that we have for 1/1. As you've seen, we're above industry growth. It is really, truly reflecting the number of years that we've been investing in Medicare, it's reflecting our starts performance, it's reflecting our expansion into different geographic counties, and really tight management of our benefit products. What I would also say to you is the way to think about our growth for 1/1 -- think about it half group and half individual.

Steven Valiquette -- Barclays -- Managing Director

Okay, that's helpful. Thanks.

Larry Merlo -- President and Chief Executive Officer

Thanks, Steve.

Our next question comes from Ricky Goldwasser from Morgan Stanley. Please go ahead.

Ricky Goldwasser -- Morgan Stanley -- Managing Director

Yeah, hi. Good morning. Larry, going back to the HHS rebate rule, I understand the questions that you raised, but assuming that the rule is finalized effective 1/1/20, it seems that there's going to be a change to the business model as we know it today. So, 1). Can you fully offset with premium increase an impact on the PDP business, 2). What would be the implications for your commercial, i.e., based on past experience, how long does it take before we see the spillover effect to commercial changes, and 3). You're in the hole on the commercial book on rebate guarantees. Is the new role a material enough change that will allow you to go back to your commercial customers and trigger a change in current contractual terms that can help offset that?

Larry Merlo -- President and Chief Executive Officer

Ricky, it's Larry. In terms of your first question around the offsets, yes, we would underwrite that with a different set of assumptions, Ricky, and some of that goes back to my earlier comments. The concern would be will people deselect from a Part D program because of the increase in monthly premiums? We know from all the research we've done over the years that beneficiaries -- that's the first thing they look at, and SilverScript has been successful growing with holding down that monthly premium level for the reasons that I touched on earlier.

Your second point, Ricky, around commercial -- our sense is -- what is it that our clients want and value? I would sit here today and say broadly, our commercial clients value the same elements that the Medicare Part D program works. They want to use the rebates and discounts to buy down the monthly premium. So, I'm not sure that I see a rapid adoption in the commercial space for that reason, and Ricky, the other thing that I would point out is I think many people are aware that Caremark introduced a new plan this year -- it was called Allure -- where it priced...it took the rebates and applied point-of-sale. We had a very small number of seniors enroll in that program -- it was around 20,000 -- and we think one of the barriers to that was the increase that we saw in the monthly premium.

Ricky Goldwasser -- Morgan Stanley -- Managing Director

Okay. So, a follow-up question here. If you can refer to -- if the change happens, can you go back and change some contractual terms? And then second follow-up is obviously, 2019 is a transition year, and you're going to give long-term guidance on your Analyst Day, but it's been over a year since you gave us a year two accretion goal. Can you give us any update there, or what type of growth should we expect next year?

Larry Merlo -- President and Chief Executive Officer

Ricky, in terms of the other question on can we go back to clients -- should there be a material change in how the programs are written, the answer to that question is yes. And, in terms, Ricky, for 2020 outlook, we're not going to provide that today. We're working diligently, recognizing that we have made great progress on the integration work that was tied to the synergy goals that we talked about, and as you think about the regulatory pathway, quite frankly, it was very late in that process that we were able to begin the transformation work in earnest. So, we're pretty pleased that we've got concept stores up and running, we've got a number of pilots in market, and a whole other series ready to go to market to learn and understand, and that is our primary objective -- to complete more of that work so that when we get to June, we will be able to provide more of a long-term outlook.

Operator

Our next question comes from Ann Hynes from Mizuho Securities. Please go ahead.

Ann Hynes -- Mizuho Securities -- Analyst

Hi, thank you. I actually just want to follow up on Ricky's question because I do think 2020 is important because when you closed the deal, you did give some directional guidance of mid-single digits, and if you adjust for tax reform, it would suggest a mid-$8.00 range. And, the reason I bring it up is because that's where your consensus estimate is now, so I know you don't want to comment on it, but what do you think that we should consider in our models as the biggest change to your business model since you gave that guidance in December of 2017, I believe? So, that's one.

Secondly, on the Retail operating profit decline, if you ex the Omnicare and, I think you said, the tax reform investment is down 5% -- I know you say it's because break-open generic is less of an offset, but I still think that's very low. Can you give us some more detail on what's happening there so we put it in our models going forward? Because it just seems a bigger decline that I would think. Thanks.

Kevin Hourican -- Executive Vice President, CVS Health and President, CVS Pharmacy

This is Kevin. I'll take the Retail question, and then Eva will talk about 2020. The primary headwind in the Retail profitability excluding Long-Term Care and the tax investment is in pharmacy reimbursement. It's impacting small operators and big operators. It's a secular headwind impacting everyone. What we talked about is a tailwind that typically is utilized to help us blunt that reduction is the generic wave, and John covered well that that value year over year is down. Eva also mentioned in her prepared remarks that there's benefit from branded inflation that helps that blunting as well, and that number is down year over year.

So, we're seeing a consistent headwind. It's the two tailwinds themselves that reduced in value year over year, and as I mentioned a few moments ago, our plan to address that for 2020 and beyond is to accelerate our top-line growth. The good news in our retail business is we are winning in the top line. We're taking market share in both the front and pharmacy business, we're resonating with consumers, growing share of vault with consumers, and taking market share.

What we need to do more of for 2020 and beyond is increase the year-over-year value of productivity improvement. We have some compelling innovations coming in technology improvement that can help automate things that are currently done manually within the pharmacies, and I'll just repeat: The most important thing we need to do is make a pivot in our third-party payer contracting. We are going to lead the change there to migrate to a new method of doing pharmacy contracting. We're going to start with ourselves.

So, by owning a large insurer and owning the largest PBM, we can lead that change by structuring a contracting relationship that if we can lower overall healthcare costs, we can take some of the burden off of the annual reimbursement reform, and where that will come from -- this is the last thing I'll say -- is we can prove through technology and clinical care programs that we can improve medication adherence, we can maximize the formulary compliance that Derica spoke to in his remarks, we can do things that are net new -- like reduce hospitalization -- through our clinical outreach program, saving Aetna money, and then we can share in the benefit of that from our Retail segment. We intend to bring that model to the other payers, and two of the other payers also own an insurance company.

Larry Merlo -- President and Chief Executive Officer

And, I just want to emphasize the last point that Kevin just mentioned because I've come to appreciate -- when you look at the Aetna business today, more than 50% of their claims have some type of outcomes-based reimbursement tied to that, and it's all on the medical side, with providers. Pharmacy has not penetrated that, and this new model is going to demonstrate the role that Pharmacy can play in terms of affecting and improving outcomes, and I think it's one of the big unlocks as you think about an open-platform concepts that we could make elements of broadly available in the market.

Eva Boratto -- Executive Vice President and Chief Financial Officer

Ann, this is Eva. I'll go back to your 2020 question. As Larry said, it's still really early to give 2020 guidance or expectations, but let me try to provide you some color. In terms of the accretion numbers that were provided back when the deal was announced, it's really difficult at this point in time to speak to those. Given the timing of the deal close, you'd have to mix and match periods as well as changes related to tax reform. But, what is 100% clear is that Aetna is performing at or better than our expectations. We absolutely stand behind the estimates of the value being created by the deal, and as we've said, we're tracking ahead of our year two synergy number of 2020.

The factors affecting what I'll say the legacy CVS business is -- as you think about 2020, all of those factors will either improve or phase out, the tax reform investment, obviously, is complete, the impact of the rebate guarantee peaks in '19 and is reduced in 2020, and we expect those Omnicare and generics to improve in 2020.

Ann Hynes -- Mizuho Securities -- Analyst

Thanks.

Operator

Our next question comes from Robert Jones from Goldman Sachs. Please go ahead.

Robert Jones -- Goldman Sachs -- Managing Director

Great. Thanks for the questions. Just to follow up there on the synergies, it clearly sounds like you're still on track. Maybe one of the other sides of it that was a little bit larger than I think we would have expected was the incremental spending in order to achieve those synergies. So, just on the numbers that you provided for this year, could you talk a little bit about what that spend is, exactly? Eva, I know you said that HCB would disproportionately benefit from the synergies this year. Is that safe to assume where the incremental spend would also come?

Eva Boratto -- Executive Vice President and Chief Financial Officer

Yeah, Bob. Thanks for the question. So, as we think about the additional investment spending, it's in the $325-350 million range. I would put that spending into two large buckets. Supporting transformation -- it includes investment in our clinical platform to more effectively engage members, our chronic care initiatives, and other initiatives aimed at improving outcomes and lowering costs. The other area that we're continuing to invest in and expand our investment is digital, and improving the digital and mobile experience for members and customers across all of our businesses, and we're making investments in our Health Cloud software platform. So, a large amount of these investments do affect the businesses. There was zero in 2019, if you will, in the denominator for which we're comparing.

Robert Jones -- Goldman Sachs -- Managing Director

Okay, and it's safe to assume, Eva, that as we roll beyond 2019, these costs should reduce? That would just be the quick follow-up. And then, the other question I had was just more housekeeping. As we look at the guide for HCB housekeeping, is prior-period development included or excluded from that guidance? Thanks.

Eva Boratto -- Executive Vice President and Chief Financial Officer

Bob, I'll take your last question first. There is no -- consistent with Aetna's legacy practices, there is no prior-period development included in our guidance. In terms of investments in the business, yeah, I do think as -- the investments will step down over time, but we will continue to invest in our business as we're evolving to our new model, with the consumer at the center.

Larry Merlo -- President and Chief Executive Officer

Bob, also just keep in mind -- to that point -- as you've heard us talk on the Retail side -- more on the CapEx side -- we have the opportunity to repurpose capital that we would have spent in areas that can be dedicated to our activities here, so that's one of the reasons why you don't hear us talking about it in that regard.

Robert Jones -- Goldman Sachs -- Managing Director

Fair point. Thanks, Larry.

Larry Merlo -- President and Chief Executive Officer

Our next question comes from Charles Rhyee from Cowen. Please go ahead.

Charles Rhyee -- Cowen & Company -- Managing Director

Yeah, hey, thanks for the questions. I just want to go back to Omnicare real quickly here. You've kind of written off maybe upwards of half of the value of what you put into it initially when you consider the debt you took on as well. It's also just two pieces you're talking about -- it's the piece that you're interested in, which was the independent assisted living market versus the SNF market. When you talk about the turnaround here, is it that you expect initiatives to grow the business in assisted living -- that's going to take off, or is that you think the declines in the SNF business are going to slow? You've been talking about this for a little bit -- what gives you the confidence here that you would expect that to turn as you get into '20?

Larry Merlo -- President and Chief Executive Officer

Charles, it's Larry. Just one quick comment on that, and then I want to flip it over to John. As you look at the Omnicare business, don't lose sight of -- there was a specialty component of that business, which has been fully integrated and quite successful for the business. So, I don't want to lose that element of the acquisition.

Jonathan Roberts -- Executive Vice President and Chief Operating Officer, CVS Health

Charles, this is John. So, what gives us the confidence that we can stabilize the long-term care -- that's the SNF. We have to think about stabilizing that. We've invested in account management personnel so that they're providing higher levels of service to the facilities. We've seen significant improvements in our service levels, and our retention rates are improving pretty significantly, and we're putting technology in that assists these facilities in communicating with the pharmacy. So, we think service ties directly to retention, and we've made significant improvements there.

And then, we still are very bullish on our ability grow in assisted living. We've implemented a new service model -- we call them "community care centers" so that there's a single point of contact with that community staff for senior living. That was not the case prior to this past year. And then, we introduced some tools that we think are going to be very attractive to these facilities, like multi-dose packaging that is better than what's available generally in the market with barcode scanning.

And then, we're also leveraging our CVS retail pharmacies for staff deliveries to these facilities, so these pharmacies are closer than the Omnicare pharmacies; they can respond more rapidly and actually develop a local relationship with these facilities along with the Omnicare pharmacy. So, we think we'll be able to not only grow our penetration rate in these assisted living facilities, but we're seeing existing clients where we didn't have all of the existed living facilities actually give us more of their facilities because of the services and changes and enhancements that we've made.

Charles Rhyee -- Cowen & Company -- Managing Director

Just to follow up with that, my understanding is that assisted living -- part of the problem with that market was that the facilities themselves didn't think of themselves as healthcare providers, more as residential communities. Is that behavior starting to change? It seems like a lot of the issues that you're discussing here are actually issues, probably, that Omnicare dealt with years ago as well, and so, placing more of a structural issue, particularly in the SNF market. Any structural changes you're seeing that you think of as being positive as you move forward here? Thanks.

Jonathan Roberts -- Executive Vice President and Chief Operating Officer, CVS Health

I think the structural changes we're seeing -- with senior living or independent living, they're trying to be able to provide continuity of care as people progress through the different phases of aging and they move from independent living to assisted living, and so, we think our value proposition will resonate even more based on these changing dynamics and what we've seen historically.

Charles Rhyee -- Cowen & Company -- Managing Director

Our final question comes from Kevin Caliendo from UBS. Please go ahead.

Kevin Caliendo -- UBS -- Executive Director

Hi, guys. Thanks for taking the call. One question I had on the Aetna business -- the Health Benefits business -- if you could just tell us on an apples-to-apples basis -- any of the shifts between the segments and the like -- what Aetna would have looked like excluding any cost shifts that you may have done into that segment and the like. What would we be looking at? That's the first question. The second question -- can you talk about the magnitude of the Centene loss? Should we expect to see that revenue loss and how it would roll -- impact the PBM margins positively or negatively going forward?

Eva Boratto -- Executive Vice President and Chief Financial Officer

Kevin, this is Eva. I'll take the first question regarding Aetna's performance without the shifts. What we're seeing -- the most clarity I can give you here is without the shifts and some of the things we've called out, we expect to see modest growth. The business has tailwinds behind it with the growth on membership in both commercial and government space, benefiting nicely from the synergies, but we're also making investments. So, the best on a same-same basis, modest growth on the bottom line -- obviously, normalizing for the health insurance fee impact.

Kevin Caliendo -- UBS -- Executive Director

Right, OK. And then, on Centene?

Derica Rice -- Executive Vice President, CVS Health and President, CVS Caremark

Hi, Kevin. This is Derica. In regard to Centene, keep in mind that it will be a multiyear migration. We anticipate that it will start in 2019, likely hit the peak in 2020, and there will probably be a residual in 2021. And, as Centene is migrating, they're looking to move to their own PBM platform, RxAdvance.

Eva Boratto -- Executive Vice President and Chief Financial Officer

And, Kevin, just to add one thing to Derica's point, while the exact timing with these large changes -- you don't know exactly how the rollout will go -- in our guidance range, we have made estimates within the range around our expected migration.

Kevin Caliendo -- UBS -- Executive Director

Got it. And, just one more -- on the well care, the PDP business that you sold the WellCare -- how is that incorporated into the numbers now, and what's the magnitude?

Eva Boratto -- Executive Vice President and Chief Financial Officer

So, WellCare -- it's a transition year. The economics still continue to benefit --

Karen Lynch -- Executive Vice President, CVS Health and President, Aetna Business Unit

Yeah, they benefit Aetna. They're still in the Aetna results as we're transitioning it out.

Kevin Caliendo -- UBS -- Executive Director

Okay, great. I just wanted to make sure they were still included in there. Okay, great. Thank you very much.

Larry Merlo -- President and Chief Executive Officer
