Interchange Naming Convention

Interchange Naming Convention (New Jersey Medicaid EDI Specifications)

Interchange Naming Convention for submission of HIPAA transactions supports the DOS file-naming convention of 8- characters followed by a 3-character extension. The file name format MUST be one alphabetic character (A – Z) or one numeric character (0 – 9) or one of eight special characters (~, @, #, $, %, ^, &, +) followed by the 7- digit EDI Submitter ID Number (assigned by DXC Technology) with the REQUIRED 3-character extension of .DAT.

The eight special characters listed are the only special characters that will be allowed. If any other special characters are used, the file will be rejected at the time of submission.

Example: A1234567.DAT or 01234567.DAT or #1234567.DAT

Any interchanges that do not follow this naming convention will NOT be processed. The EDI Submitter number in the interchange name MUST match the EDI Submitter number in the ISA. An EDI submitter can reuse the same file name used for a file previously submitted file on the same day after the EDI submitter has received the TA1 acknowledgement for the previously submitted file.

EDI submissions may include any number of claims as long as the size of the interchange being submitted does NOT exceed 40 megabytes. There is no minimum or maximum number of claims required for an EDI submission, regardless of the media or method of submission, except that the size of the interchange being submitted does NOT exceed 40 megabytes.

EDI submissions with file properties set to “READ ONLY” will NOT be accepted. Multiple interchanges may be sent daily, however an EDI Submitter is NOT to exceed more than 999 interchanges in a day (from the period of midnight to midnight). Only one ISA must be contained within a file and the file must contain only one file type, Professional, Institutional or Dental per file. If the Submitter sends multiple file types they must be sent as separate submissions. (i.e. one file containing one ISA including claims in the 837 – 005010X223A2 Institutional format only; one file containing one ISA including claims in the 837 – 005010X224A2 Dental format only; one file containing one ISA including claims in the 837 – 005010X222A1 Professional format only).

Multiple files may be submitted in a compressed format with a .zip file extension, but again the .zip file must contain only one file type, all Institutional, Dental or Professional format claims only (i.e., multiple files within one .zip file, all files containing only one ISA and all included claims are in one 837 – 5010 format only).

  • #1234567.zip – Compressed file
  • A1234567.dat – 1st file in compressed file, all Institutional claims
  • B1234567.dat – 2nd file in compressed file, all Institutional claims
  • .C1234567.dat – 3rd file in compressed file, all Institutional claims.
