Provider Appeal Requests - PRRB or Contractor Hearings

Provider Reimbursement Review Board (PRRB) Appeal Requests

Part A Providers are guaranteed the right to Appeal (42 USC 1395ooetseq) any "final determination" (NPR) with which they are "dissatisfied", providing the issue meets specific criteria of dissatisfaction, timeliness of appeal (within 180 days) and amount in controversy ($10,000 individual appeal; $50,000 group appeal). The appeal is to the Provider Reimbursement Review Board (PRRB), an independent adjudicating body of DHHS, staffed by the Office of Hearings of CMS, which serves as the "final exhaustion of administrative remedy" (Administrative Procedures Act §704) for the Provider that allows the Provider to move into the judicial system if appeal is rejected by the PRRB or CMS Administrator (oversight of PRRB). PRRB Rules

A PRRB appeal may be filed two ways: electronically through the Office of Hearings Case and Document Management System (OH CDMS) or through a hard copy submission.

While the electronic way is not currently required, the PRRB strongly recommends all parties use this new electronic case management tool. To access OH CDMS, see the CMS Electronic Filing webpage. The webpage includes a link to the CMS Enterprise Portal as well as current registration and user manuals.
