Q. Someone at Blue Cross/Blue Shield told me that in order to keep BC/BS insurance I had to have Medicare Part A & Part B. I am a retired federal worker under CSRS.
A. They were mistaken. BC/BS cannot cancel your enrollment in the FEHB program. You should enroll in Medicare Part A because you have already paid for it through payroll deductions and it will reduce your out-of-pocket expenses. Part B is optional and you would have to pay for it. Most federal retirees decline that coverage.
