Most people assume Part D open enrollment is a routine chore, something you skip if nothing major changed with your health. This fall is different. On July 28, 2026, CMS (the Centers for Medicare and Medicaid Services) announced it is ending the Part D Premium Stabilization Demonstration after December 31, 2026, a subsidy program that spent $9.8 billion over 2025 and 2026 to hold down drug plan premiums. When that support disappears, the roughly 25 million Americans enrolled in standalone Part D plans, also called PDPs (Prescription Drug Plans), will feel it in their 2027 premiums. The open enrollment window runs October 15 through December 7, 2026. But here’s the thing: the best time to prepare is right now, in August, before a single 2027 price has even been published.
I’ll be honest, when I first read the CMS announcement, I expected the usual Washington reassurance. And CMS Administrator Dr. Mehmet Oz did offer some, projecting that most beneficiaries will see increases of less than $10 per month. But independent analysts quoted in Forbes on July 31 warned that some plans could see significantly larger jumps, depending on how insurers restructure their offerings once the subsidy cushion is gone. The research here is genuinely mixed, and nobody can tell you with certainty what your specific plan will cost in 2027 until mid-to-late September 2026, when insurers release pricing. Every plan loads to Medicare.gov on October 1, giving shoppers a narrow window of just six weeks before enrollment opens. That’s why August prep matters so much.
What surprised me was how many people don’t realize this subsidy was even running. If your premium felt stable over the past two years, part of the reason was a $26 per month reduction in 2025 and a $16 per month reduction in 2026, per reporting from MedicareFAQ and Medicare Starter. Those savings were invisible, built into the premium you paid. Now they won’t be.
- CMS ended the $9.8B Part D subsidy on July 28, 2026; 25 million enrollees face 2027 premium increases.
- The subsidy cut premiums by $26/month in 2025 and $16/month in 2026; removal reverses those savings.
- CMS projects increases under $10/month; independent analysts warn some plans may cost significantly more.
- 2027 plan pricing posts to Medicare.gov on October 1, giving you just 6 weeks before Oct. 15 enrollment opens.
- The $2,000 out-of-pocket cap and $35 insulin cap remain in place for 2027.
What the Subsidy Removal Actually Means in Dollars
The stabilization demonstration didn’t just soften premiums, it masked how individual plans were actually priced. With the subsidy gone, insurers have to reflect their true cost structures in 2027 bids. Some plans may raise premiums modestly. Others may restructure formularies (the official lists of covered drugs) or shift costs into copays and deductibles rather than the monthly premium line. That’s the sneaky part. A plan that shows a small premium increase could still cost you more overall if your drugs suddenly land in a higher cost tier.
Here’s a quick look at how the subsidy’s value shifted over the two years it ran:
| Year | Average Monthly Premium Reduction | Program Cost |
|---|---|---|
| 2025 | $26/month | Part of $9.8B total |
| 2026 | $16/month | Part of $9.8B total |
| 2027 | $0 (subsidy ends) | Program ends Dec. 31, 2026 |
The declining value from 2025 to 2026 is itself telling. The subsidy was already being wound down incrementally, and now it’s gone entirely.
The Good News You Shouldn’t Overlook

Before you panic, some genuinely important protections are staying in place. The $2,000 annual out-of-pocket cap on drug costs, which took effect in 2025 under the Inflation Reduction Act, continues into 2027. So does the $35 monthly cap on insulin for Medicare beneficiaries. And the Medicare drug price negotiation program is expanding: 10 drugs already have negotiated prices, and 15 additional drugs will gain negotiated prices in 2027. If any of those 25 drugs are in your medicine cabinet, you may actually pay less for those specific medications even as the premium itself rises.
The out-of-pocket cap is especially significant for people on expensive specialty drugs. A premium increase of even $20 to $30 per month could be completely offset by catastrophic cost protection if you’re someone who previously spent thousands out of pocket annually.
What to Do Right Now, in August
You can’t compare 2027 plans yet because they aren’t published. But August is exactly the right time to do the groundwork that makes that comparison fast and accurate when October arrives.
Start with your drug list. Pull together every prescription you take, including the exact dosage, the form (tablet, capsule, injection), and how often you fill it. Don’t go from memory. Look at your pharmacy bottles or your current plan’s explanation of benefits. Include over-the-counter drugs your doctor has written prescriptions for, because those sometimes qualify for Part D coverage.
Next, know your preferred pharmacies. Medicare.gov’s plan comparison tool, which I’d strongly encourage everyone to use, lets you enter your specific drugs and your pharmacy to generate a true total annual cost estimate, not just the premium. That number is what actually matters.
Finally, check whether you qualify for Extra Help (also called the Low Income Subsidy or LIS). Extra Help is a federal program that reduces Part D premiums, deductibles, and copays for people with limited income and resources. The income and asset thresholds were expanded in recent years, and many people who previously didn’t qualify now do. You can apply through Social Security at ssa.gov or call 1-800-772-1213.
When to Actually Compare Plans
The practical answer is: start October 1, not October 15. Plans post to Medicare.gov on October 1, two weeks before enrollment officially opens. That two-week head start lets you compare without the enrollment clock ticking. The Medicare Plan Finder at Medicare.gov is the official tool, free, and it pulls real-time data from actual plan filings. Enter your drugs, your dosages, and your pharmacy, and sort by estimated annual drug cost rather than premium alone.
If you want a second set of eyes, State Health Insurance Assistance Programs, known as SHIP counselors, offer free one-on-one help from trained volunteers. Every state has one. Find yours at shiphelp.org. These counselors are not selling anything. That matters.
One more thing worth saying plainly: don’t assume your current plan will remain the best fit just because it worked in 2026. Insurers can and do change formularies, tier placements, and preferred pharmacy networks annually. A plan that covered your specific drug at a Tier 2 copay this year might move it to Tier 3 or 4 next year. The only way to know is to actually compare.
The stakes this fall are real. But the timeline is also workable. Use August to organize. Use October 1 through October 14 to compare. Use October 15 through December 7 to enroll if a better plan exists. And if you’re uncertain, please talk to a licensed Medicare counselor or your SHIP program before making any changes. This article gives you the lay of the land, but your situation is specific, and professional guidance is worth seeking.
