TA1 Error in Availity EDI 278I Realtime Request for Prior Authorizations

Question

I am trying to test the 278I Prior Authorization request with Availity and receiving a TA1 error in response. I am using the following document for reference on the 278I request. EDI-278i-Companion-Guide-Non-HIPPA-005010X215.pdf

The format of the request is as follows:

278 Inquiry Global ID - Request

Error from Availity in response

As per the documentation in few online articles and documents related to EDI Acknowledgement Errors, the line TA1 768758654 221122 0040 R*013~ means: Security Information Value is missing or incorrect.

I have been trying to figure out the issue reason here for the past two days and couldn't get it to work. It would be really great if anyone could help or guide me to solve this issue or provide some useful information related to this issue.

Answer 1

Ensure that the ISA's length is exactly 106 characters and that both ISA2 and ISA4 contain exactly 10 characters/blanks. Also, ensure that there are no hidden symbols, such as tabs, CR/LFs anywhere inside the contents. CR/LFs are okay only after the segment terminator.
