Medicare Part D Premiums Set to Rise After Discount Program Ends

If you’ve been counting on the low‑cost prescription drug plan you signed up for this year, you might want to brace for a modest bump next year. The Centers for Medicare & Medicaid Services (CMS) announced that the temporary premium‑stabilization program—created under the Inflation Reduction Act—will end on Jan. 1, 2027.

That program was essentially a financial cushion for private stand‑alone Medicare Part D plans, helping them keep monthly premiums from climbing too quickly. Now that the cushion is gone, CMS projects the average stand‑alone Part D premium will rise by roughly $10 a month.

What does that mean for you? First, you’ll get a new “Medicare & You” handbook in the mail sometime in September, and the official plan details will go live on the Medicare website around Oct. 1. That packet will spell out the exact 2027 premium, deductible, and the list of drugs covered under your current plan.

Don’t just let the plan auto‑renew without a second glance. It’s a good habit to compare your existing plan to other options—especially if you have a lot of specialty meds or you’re on a tight budget. The only window when you can actually switch a stand‑alone Part D plan—or move between a Part D plan and a Medicare Advantage plan—is during the annual open enrollment period, which runs from Oct. 15 through Dec. 7.

Here’s a quick checklist that CMS recommends:

• Check your mailbox in September for the annual notice of change; read it carefully.
• Verify that the drugs you rely on are still covered under the new terms.
• Consider whether a different plan offers a lower premium or a better formulary.
• Make any changes only during the Oct. 15–Dec. 7 enrollment window.

Remember, the discount program only applied to stand‑alone Part D plans. If your sister is enrolled in a Medicare Advantage HMO, her premiums aren’t directly affected by this change, though she’ll still get the same enrollment timeline.

Bottom line: a slight price rise is on the horizon, but with a little homework you can still land a plan that fits your needs and your wallet.
