What Happens to My Employer Coverage When I Retire?

When you retire, your active employer coverage ends. You may be offered COBRA or retiree coverage, but Medicare becomes primary. You should enroll in Part B before or when your employer coverage ends.

Frequently Asked Questions

How soon should I sign up for Part B?
Ideally, coordinate your Part B start date with your last day of employer coverage. You can apply up to 8 months after coverage or employment ends.
Should I take COBRA or Medicare?
If you're eligible for Medicare, you should enroll in Medicare rather than relying on COBRA alone. COBRA is secondary to Medicare and may not cover much.
What if I have retiree coverage?
Retiree coverage works alongside Medicare but is secondary. Enroll in Part B — your retiree plan is designed to supplement Medicare, not replace it.
