Types of Response Documents

227CA/U Acknowledgments

The 277 Claim Acknowledgment (277CA) is sent by a payer in response to an 837 to report on whether the pre-adjudication validation found them acceptable for adjudication.

The 277 Unsolicited Health Care Claim Status Notification (277U) reports the results of an application system's data content edits on the claims in a transaction set.

The 824 Application Advice (824) reports the results of an application system’s data content edits of a transaction set. Editing transaction sets results can be reported at the functional group and transaction set level, in either coded or free-form format.

The Functional Acknowledgment (997) describes the syntax-level acknowledgment of the receipt of an X12 functional group. It tells a sender that a receiver has received EDI transactions successfully.

The transaction set can be used to define the control structures for a set of acknowledgments to indicate the results of the syntactical analysis of the electronically encoded documents. The encoded documents are the transaction sets (which are grouped in functional groups) used in defining transactions for business data interchange. This standard does not cover the semantic meaning of the information encoded in the transaction sets.

The Implementation Acknowledgment (999) was first available in the X12 004061 subrelease. It is used for reporting the status of implementation guide syntax edits.

The transaction set can be used to define the control structures for a set of acknowledgments to indicate the results of the syntactical and relational analysis of electronically encoded documents, based on a full or implemented subset of X12 transaction sets. The encoded documents are the transaction sets (which are grouped in functional groups) used in defining transactions for business data interchange. This standard does not cover the semantic meaning of the information encoded in the transaction sets.

An Interchange Acknowledgment segment (TA1) is a delivery acknowledgment. It reports the receipt of the contents of one interchange control header and trailer envelope in which the envelope surrounds one or more functional groups. The TA1 reports the results of the syntactical analysis of the interchange control header and trailer. Each interchange exchanged between trading partners may contain interchange-level control segments (TA1s) related to prior interchanges.

When EDIFACT documents are exchanged between trading partners, an acknowledgment of the receipt and syntactical validation of the document can be returned to the sender of the document.

When exchanging EDIFACT documents, the CONTRL document is used to syntactically acknowledge or reject, with error indication, an interchange, group, or message received from a trading partner.

Note that CONTRL is the only message for acknowledgment in EDIFACT. In contrast, in ANSI X12 there are two messages used for acknowledgment: TA1 and 997/999 Acknowledgment.

Use of a CONTRL message for acknowledging receipt of an interchange, group, or message is not required in EDIFACT. The use of CONTRL is by trading partner agreement.
