Every year brings updates to Medicare — from premium adjustments and coverage changes to new regulatory policies. 2026 is a particularly notable year because several provisions of the Inflation Reduction Act are taking full effect, and additional policy shifts are changing how benefits work for millions of enrollees. Here is a thorough look at what is new and what you should be aware of.
Premium and Cost Updates
Part A
Most beneficiaries continue to pay $0 for Part A premiums if they or a spouse have at least 40 work credits. For those who must pay, the Part A premium can run up to approximately $565 per month for individuals with fewer than 30 credits.
The Part A inpatient hospital deductible — the amount you pay for each benefit period when admitted to a hospital — has increased modestly. For 2026, this deductible is approximately $1,736 per benefit period. The daily coinsurance amounts for extended hospital stays and skilled nursing facility care have also been adjusted upward slightly from 2025 levels.
Part B
The standard Part B monthly premium for 2026 is $203.90, a $18.90 increase from the 2025 level. Higher-income beneficiaries subject to IRMAA will pay more, with surcharges based on modified adjusted gross income from your 2024 tax return.
The Part B annual deductible is approximately $257 for 2026. After meeting this deductible, you typically pay 20% coinsurance for most Part B-covered services.
Part D
Part D premiums vary by plan, but the national average base beneficiary premium has remained relatively stable thanks in part to IRA reforms that restructured how Part D costs are shared among beneficiaries, plans, and the government. The maximum Part D deductible for 2026 is approximately $615.
The $2,100 annual out-of-pocket cap on Part D drug spending, which first took effect in 2025, remains in place. This cap continues to shield beneficiaries from catastrophic prescription drug costs.
Drug Price Negotiation Takes Effect
One of the most significant changes for 2026 is the implementation of negotiated drug prices for the first 10 medications selected under the IRA's Medicare Drug Price Negotiation Program. These are high-cost, high-utilization drugs covering conditions such as diabetes, heart failure, blood clotting disorders, and autoimmune diseases.
The negotiated prices represent steep discounts from prior costs, and beneficiaries taking these medications will see lower copays and coinsurance at the pharmacy. You do not need to take any special action — the reduced prices are automatically reflected in your plan's cost structure.
A second group of 15 drugs has already been selected for negotiation, with those prices scheduled to take effect in 2027.
Medicare Prescription Payment Plan Continues
The Medicare Prescription Payment Plan, introduced in 2025, continues to be available in 2026. This voluntary program lets you spread your annual out-of-pocket prescription costs into monthly payments, interest-free.
If you take expensive medications and prefer predictable monthly expenses rather than large upfront costs at the start of the year, contact your Part D plan to enroll. This option is available through all Part D plans and Medicare Advantage plans that include drug coverage.
Insulin Price Cap Remains at $35
The $35 monthly cap on insulin under Part D plans continues in 2026. This provision, also from the IRA, applies to all insulin products covered by your plan. Whether you use one insulin pen per month or several vials, your cost is capped at $35 for each month's supply of each covered insulin product.
This cap applies during all phases of Part D coverage — including the deductible phase — so you pay no more than $35 from day one.
Expanded Vaccine Coverage
All Part D-covered vaccines continue to be available at $0 cost-sharing for beneficiaries. This includes vaccines for shingles, RSV, Tdap, hepatitis B, and others recommended by the Advisory Committee on Immunization Practices. Before the IRA, some of these vaccines came with significant copays. That is no longer the case.
Medicare Advantage Updates
Medicare Advantage (Part C) plans are subject to several regulatory changes in 2026:
- Prior authorization reforms: CMS has continued to tighten rules around prior authorization in Medicare Advantage plans. Plans face stricter timelines for processing authorization requests and must provide more transparency about approval criteria. Some categories of services have been exempted from prior authorization requirements altogether.
- Network adequacy: Updated standards require Medicare Advantage plans to maintain adequate provider networks, particularly for specialty care and behavioral health services. Plans that fail to meet these standards may face enrollment sanctions.
- Supplemental benefits: Many Medicare Advantage plans continue to expand supplemental benefits such as dental, vision, hearing, meal delivery, transportation, and wellness programs. The specific benefits vary widely by plan and location, so comparing options during Open Enrollment remains important.
- Star Ratings adjustments: CMS has refined the Star Ratings methodology, which affects plan quality bonuses. Plans with higher ratings receive additional funding, which often translates to enhanced benefits for enrollees.
Behavioral Health and Mental Health Coverage
Medicare has continued to expand access to behavioral and mental health services in 2026:
- Marriage and family therapists (MFTs) and mental health counselors (MHCs) are now covered providers under Medicare, a change that began in 2024 and is now fully implemented
- Coverage for intensive outpatient programs remains in place, offering a structured alternative to inpatient treatment for substance use disorders and mental health conditions
- Telehealth access for mental health services continues under extended flexibilities (see below)
What Beneficiaries Need to Do
With all these changes, here is a practical list of action items:
- Review your current coverage to determine whether your plan still meets your needs. Use the Medicare Plan Finder at Medicare.gov to compare options.
- Check your medications against your plan's formulary. Negotiated drug prices and formulary changes may make a different plan more cost-effective for your prescriptions.
- Verify your income to anticipate IRMAA surcharges. If you experienced a life-changing event (retirement, divorce, death of a spouse) that reduced your income, file a reconsideration with Social Security.
- Explore the Prescription Payment Plan if you take costly medications and want to pay in monthly installments.
- Confirm your providers are in-network if you have a Medicare Advantage plan. Network changes happen annually.
- Take advantage of preventive services. Medicare covers many preventive screenings and wellness visits at no cost. Schedule your Annual Wellness Visit if you have not already.
- Update your Medicare.gov account to ensure your contact information is current and that you receive all notices and correspondence.
