Can Tricare For Life Be Primary Insurance To Medicare? 
When you have original Medicare -LRB- Medicare Part A & Part B -RRB- and TRICARE , Medicare is the primary insurance . TRICARE pays second -LRB- the idea being to lower your out of pocket expenses -RRB- . Please note , I believe you have to have both Part A & Part B of Medicare to keep TRICARE benefits when you go on Medicare , but you should double-check with the plan to be 100 % sure . I hope the information is helpful - please feel free to contact me via my profile page with any other questions . Thanks very much .
