medicare enrollment period 2026

The Medicare Open Enrollment Period for 2026 coverage ran from October 15 to December 7, 2025 , allowing eligible individuals to review, join, switch, or drop Medicare Advantage (Part C) and Part D prescription drug plans. Since today is January 12, 2026, that window has closed, but other enrollment opportunities like the Medicare Advantage Open Enrollment Period (January 1–March 31) remain open for specific changes. Changes made during the fall period take effect January 1, 2026, while premiums for Medicare Advantage plans are projected to average $14 monthly—a $2.40 drop—and Part D plans $34.50, down $3.81.

Key Enrollment Periods

Multiple windows exist beyond the Annual Enrollment Period (AEP) to fit different situations, ensuring flexibility for Medicare beneficiaries turning 65 or facing life changes.

• Initial Enrollment Period (IEP) : 7 months starting 3 months before your 65th birthday month (includes birth month + 3 after); ideal for first-time sign-up to Parts A/B.

• Annual Enrollment Period (AEP) : October 15–December 7 yearly; unrestricted changes to Advantage or drug plans for next year.

• Medicare Advantage Open Enrollment (OEP) : January 1–March 31; current Advantage enrollees can switch plans or return to Original Medicare.

• General Enrollment : January 1–March 31; for Parts A/B if missed IEP (may incur late penalties).

• Special Enrollment Periods (SEP) : Triggered by events like moving, losing employer coverage, or qualifying life changes; duration varies.

2026 Updates and Challenges

Premiums are decreasing on average, but plan networks, benefits, and formularies shift yearly—major insurers cut some extras amid rising costs. The new Medicare Plan Finder portal launched with issues like inaccurate doctor networks and plan mismatches, confusing many during AEP; experts urge double- checking via phone or SHIP counselors.

"The portal has been showing the wrong information for some plans. Sometimes listing the same doctor as both in network and out of network."

From forums and news, seniors reported frustration with these glitches, emphasizing manual verification over online tools alone.

What to Do Now (January 2026)

If you missed AEP, act during OEP if in a Medicare Advantage plan: switch for February 1 effective date (if enrolled by Jan 31). For Original Medicare users, wait for next AEP or qualify for SEP—contact 1-800-MEDICARE or shiphelp.org for free guidance. Trending discussions highlight verifying provider inclusion and drug coverage manually, as automation lags.

Period| Dates (2026 Coverage)| What You Can Do| Effective Date
---|---|---|---
AEP (Closed)| Oct 15–Dec 7, 2025| Join/switch Advantage or Part D| Jan 1, 2026 13
OEP (Open Now)| Jan 1–Mar 31, 2026| Switch Advantage plans or drop to Original| 1st of next month 15
General| Jan 1–Mar 31, 2026| Enroll Parts A/B (if eligible)| 1st of next month 1

Eligibility Basics

U.S. citizens/permanent residents age 65+ (or under 65 with disabilities like SSDI for 24 months) qualify if worked/payroll taxes paid. Automatic enrollment occurs for some; red-white-blue card arrives 3 months prior.

TL;DR : AEP ended Dec 7, 2025—use OEP now if needed; verify plans manually amid portal issues. Premiums dipped, but review annually.
