Interchange acknowledgement

Availity automatically sends negative interchange acknowledgements to your organization's ReceiveFiles folder. This file reports errors encountered within the interchange header or trailer, or functional group header, of the X12 file, particularly errors caused by duplicate interchange control numbers or an incorrect trading partner envelope.

File extensions

• .TA1 (X12 file) – This is the default format.

• .TAT (human readable text file)

When is this response file sent?

Within 24 hours, and only if errors occur.

• Negative interchange acknowledgements are not optional.

• To receive positive interchange acknowledgements, the value of ISA14 must be set to 1 in the submitted batch file. Positive interchange acknowledgements are returned with the implementation acknowledgement file (999).

Additional details

This response file reports errors (TA104) in the interchange control header (ISA) or trailer (IEA), or functional group header (GS). The following criteria are validated:

• Duplicate interchange control number (ISA13).

• Incorrect trading partner envelope, signified by an invalid value in either the interchange control header (ISA) or functional group header (GS) segments.

Next steps

When an interchange acknowledgement is generated, processing of the batch file terminates. You must correct and resubmit the entire batch, using a new interchange control number.
