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. If the review results in a denied/non-affirmed decision, the review contractor provides a detailed denial/non-affirmed reason to the provider or supplier.
Historically, Medicare review contractors, including Medicare Administrative Contractors, Recovery Audit Contractors, and Supplemental Medical Review Contractors, developed and maintained individual lists of denial reason codes and statements. If you work with multiple CMS contractors, understanding the many denial codes and statements can be hard. In 2015, CMS began to standardize the reason codes and statements for certain services to ensure providers and suppliers have a more consistent experience and that claim denials are easier to understand.
