Denial Code 56900 - Requested Records Not Submitted

  • Reason for denial:
    • The medical records were not received in response to an Additional Documentation Request (ADR) in the required timeframe; therefore, we were unable to determine medical necessity.
  • How to prevent denials:
    • Monitor your claim status on Direct Data Entry (DDE). If the claim is in status/location SB6001, the claim has been selected for review and records must be submitted. Please note: CGS may request records through our Medical Review or Claims departments, and other contractors such as the Zone Program Integrity Contractor (ZPIC) may also request records. Ensure the records are submitted to the appropriate entity.
    • Alert your mail room staff to be aware of any mail you receive from CGS.
    • Be aware of the need to submit medical records within 30 days of the date on the ADR in the upper left corner.
    • Gather all information and submit at one time.
    • Submit medical records as soon as the ADR is received.
    • Attach a copy of the ADR to each individual claim.
    • If you are responding to multiple ADRs, separate each response and attach a copy of the ADR to each individual set of medical records. Ensure each set of medical records is bound securely so the submitted documentation is not detached or lost.
    • Do not mail packages COD; we cannot accept them.
    • Return the medical records to the address indicated in the ADR.

Individual providers with significant denials will be contacted for one-on-one education.
