This technical report documents standard business operating rules and practices related to health care payments and remittance information that apply to the 835 transaction. These business rules also impact other health care business transactions since remittance information from an 835 must be reported to additional payers within the ASC X12 claim transactions (837I, 837P, 837D). As a result, the reporting requirements included here will result in changes to the information reported in secondary, tertiary and subsequent health care claims.

The technical report identifies usage standards for the Claim Adjustment Reason Codes (CARC) and Remittance Advice Remark Codes (RARC) that are conveyed initially in the ASC X12 Health Care Claim Payment/Advice (835), and then conveyed to secondary or other subsequent payers in the ASC X12 Health Care Claim (837).
