Retiree Coverage
Quick answer
Retiree coverage is a health plan an employer or union continues to offer former employees. It typically pays after Medicare, filling in some out-of-pocket costs.
Plain-English definition
Retiree coverage is not the same as active-employee coverage — Medicare almost always pays first once you're 65 and retired.
Why it matters
You need to enroll in Part B on time even if you have retiree coverage.
A simple example
Your former employer offers a retiree plan that acts like a Medigap policy alongside Medicare.

Employer Coverage
Employer coverage is a group health plan from your (or your spouse's) current job. If the employer has 20+ employees, you can usually delay Part B without penalty while you're still working.
Medigap
Medigap — also called Medicare Supplement insurance — is a private policy that pays some of the out-of-pocket costs Original Medicare leaves behind, like the Part B 20% coinsurance and Part A hospital deductible.
COBRA
COBRA lets you temporarily continue employer coverage after leaving a job. COBRA is not considered active employer coverage for Medicare, so it does not delay your Part B enrollment window.
