Title: If I have retiree coverage through the FEHB, do I need to enroll in Medicare?

Article Snip: "...Should I enroll in Part B if I have FEHB coverage? Deciding whether to enroll in Part B is complicated. And unlike Medicare Part A, all enrollees pay a premium for Medicare Part B ($171.10/month in 2022 for most people).

Conversely, FEHB plans cover emergency care received outside the United States, and this isn’t covered by Original Medicare at all – and is rarely covered by Medicare Advantage. FEHB plans may also pay for vision and dental care that’s not covered by Original Medicare and is limited in Medicare Advantage. ..."
