Do veterans need Medicare Part B?
Veterans aren't required to take Part B, but VA Healthcare is not creditable coverage for it — so declining at 65 risks a lifelong 10%-per-year penalty and a coverage gap outside the VA system. The VA itself does not recommend declining Medicare solely because you have VA care, and TFL or CHAMPVA beneficiaries must take Part B regardless.
The three-sentence answer, expanded
Part B is optional in the legal sense and consequential in every other one. VA care covers VA facilities; Part B covers the civilian world — doctors, outpatient care, and the non-VA emergencies the VA pays for only conditionally. Decline it without other creditable coverage (a 20+-employee employer plan is the legitimate exception) and the penalty compounds for life while re-entry waits on the January–March window.
The decision is real for VA-only veterans — some Priority Group 1 veterans decline deliberately — and nonexistent for TFL and CHAMPVA households, where Part B is a condition of the program itself.
