Medicare Open Enrollment 2026: Dates, Tips, and What's New

The Medicare Annual Enrollment Period is your chance to review and change coverage. Here's everything new for 2026 and how to prepare.

Every fall, Medicare's Annual Enrollment Period (AEP) gives beneficiaries a window to review their current coverage and make changes for the upcoming year. Whether you want to switch from Original Medicare to a Medicare Advantage plan, change your Part D drug coverage, or take advantage of new benefits, the AEP is your primary opportunity. Here's what you need to know for 2026.

Key Dates for 2026

What's New for Medicare in 2026

Several significant changes took effect for 2026 that may impact your coverage decisions:

Part B premium increased to $202.90/month (up from $185.00 in 2025)
Part B deductible is now $276 (up from $257)
Part D out-of-pocket cap: The Inflation Reduction Act's $2,000 annual cap on Part D out-of-pocket costs is now fully in effect
CMS has implemented stricter oversight of Medicare Advantage supplemental benefits including grocery allowances
New Medigap rate transparency requirements help beneficiaries compare plan pricing

Big Win for 2026

The $2,000 annual out-of-pocket cap on Part D prescription drug costs is the biggest change for 2026. Previously, some beneficiaries paid $5,000–$10,000+ per year for medications. This cap applies to all Part D plans and Medicare Advantage plans with drug coverage.

Your AEP Checklist

Review your Annual Notice of Change (ANOC) — your current plan mails this by September 30, detailing any changes for the coming year
Check your current medications against your plan's formulary — drug lists change annually
Verify your doctors and preferred hospital are still in-network (for Advantage plans)
Compare total costs: premiums + deductibles + copays + drug costs, not just the monthly premium
Look for new benefits like OTC cards, grocery allowances, or Part B giveback
Consider whether your health needs have changed — a plan that worked last year may not be the best fit now

Common Enrollment Mistakes to Avoid

Watch Out

Don't assume your current plan is still the best option just because it worked last year. Plans change their drug formularies, provider networks, copay amounts, and extra benefits every year. A 10-minute annual review could save you hundreds or even thousands of dollars.

Ignoring your ANOC letter — it contains critical information about changes to your plan
Only comparing premiums — a $0 premium plan with high copays can cost more than a plan with a monthly premium
Forgetting to check if your prescriptions are still covered at the same tier
Missing the December 7 deadline — after this date, you must wait until the next enrollment period
Not considering Medicare Advantage if you've only ever had Original Medicare (or vice versa)
