Even if you have coverage through current employment, you may still need to make some important Medicare enrollment decisions about Part A (Hospital Insurance) and Part B (Medical Insurance). It's important to understand how your current coverage works with Medicare before making any enrollment decisions.

If you delayed enrollment in Medicare because you were still working at age 65 and you aren't getting Social Security or Railroad Retirement benefits, you should be aware of how that decision can impact your enrollment and timing for Medicare Supplement Insurance (Medigap), Medicare Prescription Drug Coverage (Part D), and Medicare Advantage (Part C).

You'll learn when non-United States (U.S.) citizens, who move from other countries to the U.S. may qualify to get Medicare coverage. Timing of enrollment depends on their permanent resident status and how long they've lived in the U.S. It's important to understand how these elements can impact someone's eligibility and timing for Medicare.
