Acknowledgements

Acknowledgments identify the workflow status of an EDI transaction. The following ASC X12 transactions are the most common acknowledgments used in health care electronic data interchange workflow.

TA1 Interchange Acknowledgment

The TA1 is used to acknowledge the receipt of an ASC X12 interchange header and trailer pair (ISA/IEA) and to report the technical and syntactical correctness of the ISA/IEA. The TA1 Interchange Acknowledgment is described in the ASC X12 publication X12.5 Interchange Control Structures..

ASC X12C Functional Acknowledgment for Health Care Insurance (997)

This transaction is used to report the syntactical and structural integrity of the functional groups (GS/GE) within a single transmission, and to indicate whether the transmission was accepted or rejected.  The Functional Acknowledgment does not evaluate content. 

ASC X12C Implementation Acknowledgment for Health Care Insurance (999)

This transaction is used to report the syntactical and structural integrity of the functional groups (GS/GE) within a single transmission, and to indicate whether the transmission was accepted or rejected.  The Implementation Acknowledgment also reports Implementation Guide conformance (WEDI SNIP Type 1 and 2 errors).  The Implementation Acknowledgment should not be used to reject transactions that cannot be processed at the receiver’s application level (for example, invalid codes from external code sets).

ASC X12N Health Care Claim Acknowledgment (277CA)

The transaction acknowledges the validity of an ASC X12N Health Care Claim: Institutional (837I), Professional (837P), or Dental (837D) transaction at the receiver’s application level and informs the submitter whether the claim was accepted for adjudication or rejected.  

The ASC X12 Acknowledgement Reference Model provides guidance on the use of health care ASC X12 Acknowledgments.
