Denial Reason Codes

Services may be denied when individual case documentation reveals that specific coverage requirements are not met. The following links provide a list of all CGS medical review denial reason codes by provider type and the definition.

Home health and hospice agencies receive a remittance advice (RA), which communicates claim determinations. The RA displays the ANSI reason code in the "RC" or "REM" column. The reason code denial definition can be viewed online in the Fiscal Intermediary Standard System (FISS).

Medical denials are made upon medical review. Examples include:

Home Health Hospice
Care is determined to not be reasonable and medically necessary Care is determined to not be reasonable and medically necessary
Homebound criteria are not met Patient is not/no longer terminal
