Assignment means Medicare's rate is payment in full. A doctor who takes Medicare but not assignment can bill a capped amount above it; the cap is printed on your Medicare Summary Notice. A doctor who has opted out has you sign a private contract, and Medicare pays nothing. The provider search on Medicare.gov shows "accepts assignment" on every listing. One word. Assignment.
Got a bill from a doctor who "takes Medicare" that is higher than your Summary Notice says? Upload both. BillFighter compares them and writes the question.
Check your bill — freeThe check is free. The letter is the paid part: you print and mail it yourself, or we send it by certified mail for you. No account needed to start.
This is the general rule, in plain words. BillFighter is not a law firm and does not give legal advice. If you have been served with court papers, that is the day for a lawyer or legal aid.
