The Trump administration announced on July 28 that it's ending a key health insurance subsidy program designed to keep premiums for seniors' prescription drug plans down. The administration reasons that the program benefits insurance companies. But it also affects those seniors who depend on such subsidies to keep their everyday expenses in check.

The plan that will end is called the Part D Premium Stabilization Demonstration -- a two-year program created under the Inflation Reduction Act. In 2025 and so far in 2026, the plan delivered billions of dollars to Part D plans and worked to cut average prescription drug plan (PDP) premiums by $26 in 2025 and $16 in 2026.

While those bumps in premiums may seem minor, they matter to many, particularly those living on Social Security benefits alone. If you're one of the older Americans with a stand-alone Medicare Part D plan who will get hit once again with higher premiums, here are three ways you can prepare for the 2027 premium shock.

1. Get ahead of the issue

According to one administration projection, those who face a premium increase can expect it to be up to $20. To be safe, you might want to plan for $5 or $10 more. Since you know an increase is on the way, you have a chance to work it into your monthly budget. That may mean trimming discretionary spending or pulling a small amount from savings each month to reduce the shock when the bill arrives.

2. Use fall open enrollment strategically

In September, when the Centers for Medicare & Medicaid Services (CMS) publishes its 2027 premiums ahead of Medicare open enrollment (Oct. 15 through Dec. 7), use that window to:

• Compare stand-alone Part D plans to find lower-cost options that still cover your medications.
• Look into a Medicare Advantage plan with built-in drug coverage, since the subsidy change primarily affects stand-alone Part D plans, not Medicare Advantage drug premiums.
• Take advantage of Medicare's comparison tools during open enrollment to help minimize healthcare costs as much as possible. You may find that switching to another plan will be more than enough to offset a higher Part D premium.

3. Shop smart

Premiums are only a part of total drug costs. Your doctor knows what you're up against. Work with this medical provider to:

• Switch to generics or lower-cost alternative drugs when it's medically appropriate.
• Find out which preferred pharmacies or mail-order options are included with your plan. Once you know, check prescription prices to learn if you can save money by switching where you purchase your drugs.
• Periodically go through your list of medications to ensure you still need the drugs you're paying for. Be sure to have your medical provider help you make the final decision.

For millions of Americans, the ever-creeping cost of medical care may not have been part of the long-term retirement dream. However, by planning, you can navigate the end of the subsidy with less financial strain.
