999 Implementation Acknowledgment
Functional Group FA
X12C Communications and Controls Subcommittee
This X12 Transaction Set contains the format and establishes the data contents of the Implementation Acknowledgment Transaction Set (999) for use within the context of an Electronic Data Interchange (EDI) environment. 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 the electronically encoded documents, based upon 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.
What is an EDI 999?
An EDI 999 Implementation Acknowledgement serves as a response to healthcare-related EDI messages or groups of messages. Like the EDI 997 Functional Acknowledgement, it contains important information about the receipt of the upstream document (AK2 segment), and whether or not the receiver accepts or rejects the document as presented (IK5 and AK9 segments). It must be HIPAA 005010 complaint.
How is an EDI 999 used?
For example, Employer A sends Insurance Provider B an EDI 834 Benefit Enrollment and Maintenance to enroll a new employee into a healthcare benefits plan. Insurance Provider B responds with a 999 to confirm that the EDI 834 Benefit Enrollment and Maintenance was received with no errors.
