Role of MSP Contractors in MSP Liability Appeals Process

40.25 – Role of MSP Contractors in MSP Liability Appeals Process (Rev. 12438; Issued: 01-04-24; Effective: 02-06-24; Implementation: 02-06-24) The MSP Contractors conduct liability appeals. There are statutory appeal processing timeliness requirements which require prompt action on the part of CMS. See 42 C.F.R. 405.950. For processing timeliness, the MSP Contractor uses the date of receipt in the mailroom as the date of receipt. The date the beneficiary or applicable plan filed the request with the MSP Contractor is used to determine if the beneficiary, or applicable plan, filed timely.
