Quick answer

A Medicare Special Enrollment Period (SEP) lets you enroll in or change Medicare coverage outside the usual windows after a qualifying life event, such as losing employer coverage or moving. Losing active employer coverage triggers an eight-month SEP for Part B, usually with no late penalty.

Life events can open a Special Enrollment Period, letting you act outside the normal Medicare windows. Here is how they work.

What triggers a Special Enrollment Period?

Several life events open an SEP. The most common is losing active employer or union group coverage, which gives you an eight-month window to enroll in Part B without penalty. Others include moving out of your plan's service area, moving into or out of a nursing facility, losing Medicaid eligibility, qualifying for Extra Help, or your plan leaving Medicare. Each event has its own rules and timeline. Missing the window can mean penalties or a coverage gap, so it pays to act quickly. Call 1-800-MEDIGAP to confirm whether you qualify.

How do I use a Special Enrollment Period?

Once a qualifying event occurs, you generally have a set window, often two months for Medicare Advantage and Part D changes, or eight months for Part B after employer coverage ends, to make your change. You may need to provide documentation, such as proof of prior coverage. Acting promptly protects you from penalties and ensures continuous coverage. Because the rules vary by event and missing a deadline is costly, getting expert help is wise. A licensed agent at 1-800-MEDIGAP can confirm your SEP and handle the enrollment for you.

Does moving qualify me for a Special Enrollment Period?+
