Medicare Assignment CalculationThe set amount that Medicare pays doctors, hospitals and other health care providers for specific procedures and items is called assignment. If a doctor agrees to accept what Medicare will pay as full payment for the bill, he or she has accepted assignment and you won’t be charged anything additional (though copayments and deductibles may still apply).


Even though the medical center would normally charge more for the lab work, it accepted assignment for the services and required nothing further from the patient.
