Do I Need Medicare Part B If I'm Still Working?

If you're approaching 65 and still working, you've probably heard conflicting advice about Medicare Part B. Some people say enroll right away; others say wait. The truth is that it depends on your coverage — and getting it wrong can be costly.

This guide walks the questions that actually decide it, so you can confirm your timing before you delay anything.

The question isn't simply whether you're still working. It's how your current coverage works with Medicare.

Part B is the medical side of Medicare, and it usually carries a monthly cost. Because of that, many people who are still working wonder whether to take it now or wait. The confusion comes from the fact that the right answer depends on the kind of coverage you already have — not just your age.

The key distinction is whether your coverage is active employer group coverage — insurance through a job you or your spouse currently hold. Active employer coverage may let you delay Part B without a penalty. Other kinds of coverage, like retiree plans or COBRA, are often treated differently, which is where mistakes happen.

The size of the employer can change how Medicare and your employer coverage work together — including whether Medicare would be primary or secondary. Because the rules can differ for smaller and larger employers, it's worth confirming how your specific employer coverage coordinates with Medicare.

If you're covered through a spouse's current employer rather than your own, similar questions apply — and the details of that plan matter. Whether it counts as active employer coverage, and how it coordinates with Medicare, can affect whether delaying Part B is safe for you.

Retiree coverage is generally not treated the same as active employer coverage for Medicare timing. If your coverage comes from a former employer's retiree plan, don't assume it lets you delay Part B — confirm it specifically.

COBRA can feel like a continuation of employer coverage, but for Medicare timing it's usually treated differently. Relying on COBRA to delay Part B can create a late-enrollment penalty, so this is one to verify carefully before you decide.

Your employer's benefits administrator can usually answer the questions that decide your timing. A short conversation now can prevent a lasting penalty later.

If the answers still feel unclear, that's a good moment to talk with someone local. A 20-Minute Fit Check can help you line up your coverage details, confirm your timing, and avoid a penalty — based on your situation, not a guess.

Working past 65 doesn't have to make Medicare stressful. Confirm how your coverage works first, and the Part B decision gets a lot clearer.
