Key takeaways:
- Covered insulin costs no more than $35 a month, and Part D adult vaccines cost nothing out of pocket.
- Part D now has a hard annual out-of-pocket ceiling — $2,000 when it started in 2025, rising each year after. The old coverage gap, or “donut hole,” is gone.
- Medicare has negotiated prices on a first round of high-cost drugs, effective in 2026.
- The trade-off: insurers may respond with higher premiums, tighter drug lists, and more prior authorization — and some are pulling Medicare Advantage and Part D plans out of certain counties entirely.
- Review your plan’s Annual Notice of Change every fall, even if nothing looks wrong.
When it comes to Medicare, this year has brought some serious updates—particularly through the Inflation Reduction Act and changes affecting Medicare Advantage plans. Whether you’re experienced in the Medicare world or new to the landscape, it’s important to understand how these shifts might impact your coverage and out-of-pocket costs. Let’s cut through the noise and break down the key changes so you can stay prepared and well-covered.
Medicare Basics Refresher
Medicare’s a federal program that covers folks 65 and older, along with younger people with disabilities and those with End-Stage Renal Disease (ESRD). Here’s a quick breakdown of the four Medicare parts:
- Part A: Covers hospital care.
- Part B: Covers medical services.
- Part C (Medicare Advantage): Private plans bundling Parts A and B.
- Part D: Prescription drug coverage.
Inflation Reduction Act: What’s in It for Medicare Beneficiaries?
The Inflation Reduction Act (IRA), signed into law in 2022, aims to bring down prescription drug costs for Medicare users, focusing heavily on Part D and Medicare Advantage. Here’s what the act brings to the table:
- Insulin Price Cap: If you use insulin, there’s some good news—Medicare has capped monthly insulin costs at $35, which began in 2023. It applies to covered insulin, so a price jump at the pharmacy usually means something else changed — most often your plan’s drug list.
- No-Cost Adult Vaccines: Also since 2023, vaccines under Medicare Part D are available at no cost to adults, which can keep you protected without unexpected expenses.
- Out-of-Pocket Spending Cap: According to CMS, since 2025, out-of-pocket expenses for Part D prescriptions have been capped, starting at $2,000 in that first year and adjusted upward each year after. That’s real relief for those with high prescription costs, and it’s also what replaced the old coverage gap.
- Medicare Drug Price Negotiations: Medicare negotiated prices on a first round of high-cost drugs, and those prices took effect in 2026, making certain medications more affordable. CMS publishes the full drug list and timeline through its Medicare Drug Price Negotiation Program.
The Impact of These Changes on Your Medicare Coverage
While these provisions aim to make drugs more affordable, insurers and industry analysts have flagged some potential side effects. None of these is guaranteed, and how much you feel them depends on the plan you hold:
- Potential for Higher Part D Premiums: With caps on insulin and other drugs, insurers may raise premiums to balance these cost limits.
- Reduced Access to New Medications: Some pharmaceutical companies might delay releasing new drugs to the Medicare market.
- More Prior Authorizations: Plans may tighten restrictions to access specific drugs, requiring more prior authorizations.
- Narrower Formularies: A formulary is simply the list of drugs your plan agrees to cover. Certain plans may cover fewer drugs overall to offset the cost impacts of the IRA, so it is worth knowing what your options are if one of your prescriptions comes off the list.
Medicare Advantage and Service Area Reductions
One significant change hitting Medicare Advantage plans is Service Area Reductions (SARs), where an insurance provider pulls its Medicare Advantage or Part D plan out of specific regions. This can leave beneficiaries in affected areas scrambling to find a new plan or risk defaulting to Original Medicare if they don’t pick a replacement. If your plan is leaving your area, it has to tell you in writing in your Annual Notice of Change, and a plan non-renewal generally opens a Special Enrollment Period so you are not locked out of switching.
What's the financial risk of sticking with Original Medicare without a Medigap plan?
20% unlimited coinsurance, Part B 15% excess charges, and lots of daily hospital copays... that’s after the smaller deductibles, of course.And you might not be able to get one later.

The bottom line is that the landscape is shifting, but you’re not alone in navigating it.

When should my plan be reviewed?
The annual election period is typically when plans are reviewed, but if you’re on a Medicare Supplement plan, the best time to review it is anytime of year that you get a rate increase letter, or, in some states, on your birthday or policy anniversary.If you don’t know when is best for you, the answer is NOW.
