Explanation Codes


The former MDCH explanation codes are obsolete and are not used for claim adjudication within CHAMPS.  Providers must instead refer to the HIPAA compliant Claim Adjustment Reason Codes (CARC) and Remittance Advice Remark Codes (RARC) available through the CHAMPS claim inquiry process or included with the remittance advice. Please visit the Washington Publishing Company website for a complete listing and description of the HIPAA CARC and RARC codes at
