In the 999 TR-3, the element IK402 is for reporting the data element reference number of the element in error. This element is defined as numeric (N0). How can a situational error in CLM05, that has a reference number of C203, be reported? How can any other data element reference number that comes from a composite data element be reported in IK402 of the 999?
The implementation guide 005010X231A1 gives specific guidance concerning this situation for CTX05-1. IK402 and CTX05-1 are both data element 725. It is recommended the same guidance for CTX05-1 be used for IK402. Required when CTX05 is used and the data element reference number of the data element identified in CTX05-1 is known by the submitter of the 999 and it is NOT a composite data element. ASC X12 has completed data maintainence on DE 725, modifying the data type from (N0) to (AN) in furture versions of the standard.
