Medicare and Working
If you are still working when you become eligible for Medicare, your coverage decisions can be more complex.
Your choices depend on your employer insurance, timing, and how Medicare coordinates with other coverage.
Understanding how Medicare works while you are working helps you avoid penalties and choose the right coverage.

Do You Need Medicare If You’re Still Working?
Whether you need Medicare depends on your situation.
If you have employer coverage, you may be able to delay certain parts of Medicare without penalties.
However, the rules vary depending on the size of your employer and the type of coverage you have.

COBRA and Medicare
COBRA allows you to continue employer coverage after leaving a job, but it does not replace Medicare.
Delaying Medicare while on COBRA can lead to penalties and gaps in coverage.

Does COBRA Count as Creditable Coverage?
COBRA is not considered creditable coverage for delaying Medicare enrollment.
This means you should not rely on COBRA to avoid enrolling in Medicare on time.

If you have a Health Savings Account (HSA), Medicare enrollment affects your ability to contribute.
Once you enroll in Medicare, you can no longer make HSA contributions.
