Medicare Plan Changes 2026

Every year, Medicare changes. And every year, some people miss important updates that affect their costs, their doctors, or their prescription coverage — not because they didn’t care, but because they assumed their plan simply renewed with the same terms it had the year before.

For 2026, that assumption is particularly costly. Part B premiums crossed $200 per month for the first time in Medicare history. Deductibles rose across Parts A, B, and D. And a meaningful number of Medicare Advantage plans reduced supplemental benefits, changed provider networks, or exited markets entirely.

This page covers every major 2026 Medicare change — with plain-language explanations and the actual CMS-confirmed numbers, not projections.

The most significant Medicare updates for 2026 span every part of the program. Here’s a summary before we go deeper into each area:

Not every change affects every person equally. But even small adjustments — a drug moving to a higher tier, a copay increasing, a doctor leaving a network — can meaningfully affect your total annual healthcare spending. That’s why annual review matters regardless of how satisfied you were with your plan last year.

Medicare Part B covers outpatient services — doctor visits, specialist care, lab work, preventive services, durable medical equipment, and more. The Part B premium is the foundation of your Medicare coverage. It applies whether you have Original Medicare with a Supplement plan, or a Medicare Advantage plan.

For 2026, the standard monthly Part B premium is $202.90 — an increase of $17.90 from $185.00 in 2025, and the first time it has ever exceeded $200. The annual Part B deductible is $283, up $26 from $257 last year.

Higher-income beneficiaries pay additional surcharges on top of the standard premium. See the IRMAA section below for the 2026 income brackets and what they mean for your costs.

Most people don’t pay a premium for Part A — as long as they or their spouse worked and paid Medicare taxes for at least 40 quarters (10 years). But Part A carries deductibles and coinsurance costs that apply when you’re admitted to a hospital or skilled nursing facility.

Medicare Advantage plans (Part C) are offered by private insurance companies and are permitted to change their benefits, costs, and networks every single year. For 2026, the changes have been more significant than most recent years — and more tilted toward reductions than expansions.

According to CMS, approximately 5,600 Medicare Advantage plans are available nationwide in 2026, down slightly from 5,633 in 2025. That reduction may seem small nationally, but in specific counties the impact is more pronounced — fewer plan choices, reduced competition, and in some areas, plans exiting altogether.

Average Medicare Advantage premiums with integrated drug coverage decreased to approximately $11.50/month in 2026 (down from $13.32 in 2025). Many plans continue to carry a $0 premium. But a $0 premium plan is not a zero-cost plan. Copays, coinsurance, and out-of-pocket maximums still apply — and those numbers determine your true cost exposure when you actually need care.

Every Medicare Advantage plan has a Maximum Out-of-Pocket limit — the most you’d pay in-network for covered services in a calendar year. The federal cap on MOOP decreased slightly for 2026, which is a modest improvement. However, plan-specific limits vary widely. A plan with a $10,000 MOOP and a $0 premium can be far more expensive than a plan with a $50 premium and a $4,500 MOOP if you need significant care. See how Advantage and Supplement plans compare on cost exposure.

This is where 2026 stands apart from recent years. Many Medicare Advantage plans that had been aggressively expanding extras — dental allowances, over-the-counter credits, vision and hearing coverage, transportation, gym memberships — pulled those benefits back for 2026.

This is one of the most overlooked annual changes — and one of the most disruptive. Doctors and hospitals can join or leave Medicare Advantage networks between plan years. A physician who was in-network in 2025 is not guaranteed to remain in-network in 2026. If you have doctors you depend on, confirm they are still participating in your plan before assuming continued access. An HMO plan without your doctor in network is a fundamentally different product than one that includes them.

Some plans shifted from flat copays to percentage-based coinsurance for certain services in 2026 — a change that can significantly increase out-of-pocket costs for expensive procedures. Even modest copay increases on primary care visits or specialist appointments add up across a year of regular care. Review your 2026 Summary of Benefits carefully, especially for services you use frequently.

Prescription drug coverage is one of the most variable parts of Medicare from year to year. Part D plans may adjust drug formularies, tier placements, pharmacy networks, prior authorization requirements, and deductibles annually — often without prominent notice to enrollees beyond the Annual Notice of Change mailed in September.

The $2,000 out-of-pocket cap on drug costs — introduced in 2025 — remains in effect for 2026. Once you reach $2,000 in covered out-of-pocket drug spending, your plan covers 100% of remaining covered drug costs for the rest of the year. This is a meaningful protection for people on expensive specialty or maintenance medications.

Medicare Supplement plans offer more stable year-to-year coverage than Medicare Advantage. The actual benefits of standardized plans like Plan G or Plan N don’t change — Plan G in 2026 covers the same things it covered in 2025.

What can change is your premium. Carriers review rates annually and may increase premiums based on age, claims experience, or their pricing methodology. If you received a renewal notice with a significant rate increase, it is worth comparing what other carriers charge for the same plan in your area. The benefits are identical across all carriers offering Plan G — but premiums often are not.

One important note on switching: Moving from one Supplement plan to another outside your guaranteed issue window typically requires medical underwriting in most states. A pre-existing health condition could result in denial or higher rates. Understanding these rules before making any changes is critical — the wrong move at the wrong time can close doors permanently.

If your income exceeds certain thresholds, Medicare adds a surcharge — called IRMAA (Income-Related Monthly Adjustment Amount) — on top of your standard Part B and Part D premiums. For 2026, IRMAA applies to individuals earning over $109,000/year, or married couples earning over $218,000 filing jointly.

IRMAA uses a two-year look-back: your 2024 income determines your 2026 IRMAA. If you recently retired or experienced a significant drop in income, you may be able to appeal your determination using Form SSA-44, which allows you to use more recent income data rather than waiting for your tax returns to catch up.

In most cases, yes — your Medicare Advantage or Part D plan automatically renewed on January 1, 2026 unless the plan exited your county or you made a change during the Annual Enrollment Period (October 15 – December 7).

But automatic renewal is not the same as unchanged coverage. Your plan may have renewed with different copays, a revised drug formulary, or a narrower provider network. The plan you had on December 31, 2025 may not be functionally identical to what you have today — even if it carries the same name and plan number.

Switching plans is not always the right move — but it’s worth evaluating seriously if any of the following apply to your situation this year:

The most common Medicare mistake isn’t a wrong decision — it’s no decision. Assuming nothing changed, not reviewing the Annual Notice of Change, and letting coverage auto-renew without examination. Here’s what a thorough annual review actually looks like:
