The day you leave your Employer Plan, your Medicare clock starts.

Retirement changes your Medicare timeline, and most people don’t realize the clock is already running until they’re behind it.

The biggest trap is COBRA. Most people assume COBRA protects them the way employer coverage did. It doesn’t work that way for Medicare, and that misunderstanding creates a penalty that stays with you.

Before retirement arrives, let’s get your timeline right.

COBRA is not creditable coverage for Medicare.

This is the one that surprises people the most. When you retire and take COBRA instead of enrolling in Medicare, COBRA does not protect you from the Part B penalty. I’ve seen people believe they were covered, only to find out the coverage came back with a penalty attached.

Timing your enrollment around your Retirement Date.

When your employer coverage ends, a Special Enrollment Period opens for Medicare. Coordinating your enrollment with your actual retirement date, so there’s no gap and no penalty, is the whole game. Start too late and you’re exposed.

Keeping your prescriptions covered through the transition.

Your prescription coverage doesn’t automatically carry over. As you move off employer coverage, you need a Part D plan that actually covers your medications. Reviewing your prescriptions during this transition prevents a nasty surprise at the pharmacy counter.
