Reason Code 5H507: SNF MDS Is Not in the National Repository

Published 11/12/2019

The MDS cannot be accessed in the National Repository.

To Prevent This Denial

  • Ensure that the MDS has been entered into the National Repository prior to submitting request for payment to Medicare
  • Check all bills for accuracy and ensure that the MDS clinical assessment includes data for all covered days associated with the billing period

For more information, refer to CMS Internet-Only Manual (IOM), Medicare Program Integrity Manual Publication 100-08, Chapter 6, Section 6.1.3 (PDF).
