Reason Statements and Document (eMDR) Codes

Centers for Medicare and Medicaid Services (CMS) contractors medically review some claims and prior authorizations to ensure that payment is billed or authorization is requested only for services that meet all Medicare rules.

Currently, review reason codes and statements are available for the following services/programs:
