Voluntary Refunds
12.12 – Voluntary Refunds
(Rev. 852; Issued: 12-21-18; Effective: 1-24-19; Implementation: 1-24-19)
This section applies to Medicare Administrative Contractors (MACs) and Comprehensive
Error Rate Testing (CERT) as indicated.
If the MAC receives a voluntary refund from a provider or supplier on a CERT sampled
claim, the MAC shall process the voluntary refund normally, as instructed in other
manuals. If the MAC processes the voluntary refund of a CERT sampled claim after
receiving the transaction file for the claim in question, the MAC shall complete the
feedback file as though the voluntary refund had not been received.
