277CA

X12 277CA, the claim-level acceptance/rejection report sent back after an 837 submission.

Definition

Unlike the 999 (which checks X12 syntax of the whole interchange), the 277CA reports business-level acceptance of individual claims, using STC status category and status codes to flag accepted, pending or rejected claims so providers can correct and resubmit before adjudication.

Origin

Defined by the ASC X12N TR3 implementation guide for the 277 Health Care Claim Acknowledgement and required as the claim-status acknowledgement under the CAQH CORE operating rules adopted for HIPAA administrative simplification.

Example in context

STC*A1:19:PR*20260620*WQ*150~ status category A1 (acknowledgement/receipt) signals the claim was accepted into the payer's adjudication system.
