Medicare Special Enrollment Periods and Qualifying Life Events

A Medicare Special Enrollment Period (SEP) is a limited time outside the standard Medicare enrollment windows when you can enroll in or change plans due to specific qualifying life events, such as moving, losing creditable employer coverage, or qualifying for financial assistance like Extra Help. The most important feature of SEPs is the ability to make necessary coverage changes and, in some cases, avoid late enrollment penalties.

Why Medicare Special Enrollment (SEP) Matters

A Medicare Special Enrollment Period (SEP) takes place when certain events or life changes occur, giving you the opportunity to make changes to your existing Medicare Advantage plan and Medicare Prescription Drug plan. This helps ensure that your Medicare coverage is still the right fit for your circumstances. An SEP also allows individuals who delay Medicare Part B enrollment due to having current employer group health coverage to sign up without penalty. By enrolling during the SEP (usually an eight-month window after the employment or coverage ends), they avoid the permanent late enrollment penalty.

Events That Qualify You for a Medicare Special Enrollment Period

There are several types of Medicare Special Enrollment Periods, with different qualification standards for each. Some of the most common Special Enrollment Period qualifying events include:

Moving Out of Your Plan's Service Area

Qualifying changes in location include:

• Moving to a new address that isn’t in your current Medicare plan’s service area

• Moving to a new location where new Medicare plan options are available, even though your current Medicare plan also includes coverage for your new address

• Returning to the U.S. after living outside the country

• Moving in or out of a skilled nursing facility or long-term care hospital

• Being released from jail
  
  

Losing Creditable Coverage or Other Entitlement

If these statements apply to you, you may be eligible for a Special Enrollment Period.

• I’m no longer eligible for Medicaid.

• I left coverage from my employer or union (including COBRA).

• I involuntarily lost drug coverage that’s as good as Medicare drug coverage.

• I had drug coverage through a Medicare Cost plan, and I left the plan.

• I dropped my coverage in a Program of All-inclusive Care for the Elderly (PAC) plan.

• You have the chance to join other coverage offered by your employer or union.

• You have or plan to enroll in other drug coverage that’s as good as Medicare drug coverage.

• You enrolled in a Program of All-inclusive Care for the Elderly (PACE) plan.
  

Changes to Your Current Plan’s Status with Medicare

You may also qualify for a Special Enrollment Period if your plan’s contract with Medicare changes. This could look like:

• Medicare takes a sanction against the plan you’re enrolled in.

• The state takes over your plan because of financial issues.

• Medicare terminates your plan’s contract, or your plan ends its contract with Medicare.

• Your plan’s contract with Medicare isn’t renewed.

What else should I know about Special Enrollment Periods?

If you delayed enrollment in Medicare Parts A and B because you or your spouse worked after turning 65 and are losing your group coverage, you typically qualify for a Special Enrollment Period for Original Medicare (Medicare Part A and Medicare Part B). During this SEP, you may:

Enroll in Part B (and Part A if you haven’t already). You’ll be given a Special Enrollment Period of eight months to sign up starting the month that follows the end of your employer coverage.
Enroll in Medicare Advantage (Medicare Part C) or a Prescription Drug plan (Medicare Part D). You have two months to enroll in these options.

Additionally, there’s a Medicare Advantage SEP for individuals who are dual-eligible or who receive “Extra Help” (also known as Low-Income Subsidy). Extra Help is a federal program that helps pay for some to most out-of-pocket costs of Medicare prescription drug coverage. If you receive Extra Help in 2025, there is a SEP to enroll in a Medicare Advantage plan with or without drug coverage, a Part D plan, or to switch between plans. This SEP is available once per quarter for the first three quarters of the year (January through March, April through June, and July through September). Coverage changes become effective the first day of the month following the change.
