When assignment is accepted, Medicare Part B recommends:
- Since it is difficult to predict when deductible/coinsurance amounts will be applicable - and over-collection is considered program abuse - do not collect these amounts until you receive Medicare Part B payment.
- If you believe you can accurately predict the coinsurance amount and wish to collect it before Medicare Part B payment is received, note the amount collected for coinsurance on your claim form. (We do not recommend that you collect the deductible prior to receiving payment from Medicare Part B because, as noted above, over-collection is considered program abuse and can cause a portion of the provider's check to be issued to beneficiaries on assigned claims.)
- Do not show any amounts collected from patients if the service is never covered by Medicare Part B or you believe, in a particular case, the service will be denied payment. Where patient paid amounts are shown for services that are denied payment, a portion of the provider's check may go to the beneficiary.
