Medicare 2026

Missed the Dec. 7 Medicare Deadline? Here Are Your Options for 2027

If December 7, 2026 came and went without you making a Medicare choice for 2027, take a breath. The Annual Enrollment Period (October 15–December 7, 2026) is the main window for picking a Medicare Advantage plan or a stand-alone Part D drug plan, but it is not your only chance to act. Depending on your situation, you may still have a path to change coverage, correct a mistake, or line up something new for the year ahead.

First, confirm what you actually have for January

Before assuming you are stuck, check your mail and your plan documents. If your current Medicare Advantage or Part D plan is continuing in 2027 and you made no change, you are simply enrolled in that plan for the new year. Benefits, networks, formularies, and premiums can change year to year, so read the Annual Notice of Change your plan sent in the fall.

If your plan is ending, your insurer must send a non-renewal notice. In that case, you have a Special Enrollment Period that runs through the end of February to pick new coverage. That window is designed specifically so no one is left without a path forward when a plan leaves the market.

The Medicare Advantage Open Enrollment Period (January 1 – March 31)

If you are enrolled in a Medicare Advantage plan on January 1, 2027, you have one more built-in opportunity: the Medicare Advantage Open Enrollment Period, which runs January 1 through March 31. During this window you can make one change — switch to a different Medicare Advantage plan, or drop Medicare Advantage and return to Original Medicare (and add a stand-alone Part D plan if you want drug coverage).

This window does not apply if you are in Original Medicare on January 1. And it only allows one change, so use it carefully.

Special Enrollment Periods tied to life events

Medicare has a long list of Special Enrollment Periods for specific circumstances, including:

• Moving out of your plan's service area or to a new area with different plan options
• Losing employer or union coverage
• Moving into, living in, or moving out of a nursing home or other institution
• Your plan ending its contract or leaving the program

If any of these apply, you may be able to enroll or switch outside the normal windows. The timing and length of each SEP vary, so confirm the rules on Medicare.gov or by calling 1-800-MEDICARE before you act.

If you have Medicaid or Extra Help

If you qualify for Medicaid or the Extra Help program for Part D costs, you have more flexibility than most. Since 2025, there is a monthly Special Enrollment Period that lets you move to Original Medicare with a stand-alone Part D plan — or switch from one stand-alone Part D plan to another — once per month. If you are a full-benefit dual-eligible (enrolled in both Medicare and full Medicaid), you can also join an integrated Dual Eligible Special Needs Plan (D-SNP) in any month of the year.

The five-star Special Enrollment Period

If a Medicare Advantage plan or stand-alone Part D plan in your area carries CMS's five-star overall rating, you can use the five-star SEP to switch into it once between December 8 and November 30. This is a year-round option, independent of Annual Enrollment.

What is changing for 2027 that is worth knowing

A few program-level facts are already set for 2027:

• The Part D out-of-pocket cap rises to $2,400 (up from $2,100 in 2026). Once your out-of-pocket drug spending reaches that amount, you pay nothing more for covered Part D drugs for the rest of the year.
• The most any Part D plan may charge as a deductible in 2027 is $700. Individual plans may charge less.
• The Part D base beneficiary premium for 2027 is $41.33. This is a national figure used to calculate the late-enrollment penalty; actual plan premiums vary.
• The Social Security Administration announced a 3.6 percent cost-of-living adjustment for benefits payable starting January 2027.

Some figures for 2027 have not been announced yet, including the standard Part B premium and deductible and the IRMAA income brackets that determine higher premiums for Part B and Part D. CMS typically releases these in the fall. Watch Medicare.gov for the official numbers rather than relying on estimates.

Weighing Medicare Advantage vs. Original Medicare + Medigap

If a Special Enrollment Period or the Medicare Advantage Open Enrollment Period gives you a chance to change paths, it is worth understanding the trade-offs rather than chasing a label.

Medicare Advantage plans bundle hospital, medical, and usually drug coverage into one plan, often with extra benefits, but they use networks and prior authorization, and plan details vary.

Original Medicare paired with a Medigap (Medicare Supplement) policy and a stand-alone Part D plan generally gives you broader provider access and more predictable out-of-pocket costs, but Medigap has its own premium, and Medigap enrollment protections depend on timing and your situation.

Neither approach is "better" universally — the right fit depends on your health, your doctors, your prescriptions, your budget, and how you like to manage care.

Where to get accurate, personalized help

For official enrollment windows, plan comparisons in your area, and current-year rules, go to Medicare.gov or call 1-800-MEDICARE (1-800-633-4227), available 24 hours a day, seven days a week. Missing December 7 is not the end of the road — but your next move should be based on the rules that actually apply to your situation.
