Collection of Funds and Refunds
50.15 - Collection of Funds and Refunds
(Rev. 10862; Issued: 07-14-21; Effective: 10-14-21; Implementation: 10-14-21)
Collection of Funds
A beneficiary’s agreement to be responsible for payment on an ABN means that the
beneficiary agrees to pay for expenses out-of-pocket or through any insurance other than
Medicare that the beneficiary may have. The notifier may bill and collect funds from the
beneficiary for non-covered items or services immediately after an ABN is signed, unless
prohibited from collecting in advance of the Medicare payment determination by other
applicable Medicare policy, State or local law. Regardless of whether they accept
assignment or not, healthcare providers and suppliers are permitted to charge and collect
the usual and customary fees; therefore, funds collected are not limited to the Medicare
allowed amounts.
If Medicare ultimately denies payment of the related claim, the notifier retains the funds
collected from the beneficiary unless the claim decision finds the healthcare provider or
supplier liable. When Medicare finds the healthcare provider or supplier liable or if
Medicare or a secondary insurer subsequently pays all or part of the claim for items or
services previously paid by the beneficiary to the notifier, the notifier must refund the
beneficiary the proper amount in a timely manner.
