I plan on still working when I turn 65. According to Medicare, I can wait to sign up for Medicare Part B since I’ll continue to have health insurance through my employer. How does this affect my TRICARE?

 

Although you can sign up for Part B later, you won’t have TRICARE coverage if you don’t have Medicare Part B. Once you sign up for Part B, your TRICARE For Life coverage starts the same day your Part B starts.
