How does one obtain X12 EDI specs?

Question

Specifically, 835 and 837, and even more specifically, lists of the various status codes and their meanings.

I've found a couple of commercial sources via google and duckduckgo. Are any sources freely available?

Thanks.

Answer 1

The specifications are copyrighted by DISA or WPC (in the case of the HIPAA standards -- which are essentially an augmented version of the base X12 standards) and available for purchase from them.

As Axel suggested however for the more popular transactions sets you can usually obtain implementation guides from the net, and these will generally have all what you need.

There are generally not machine readable versions of these specifications freely available, as the official versions cost a great deal.

Answer 2

One option is to ask Google for the specific message types like Health Care Claim Payment/Advice (X12 835). This will show you loads of guides and documents.

Another option is to download a trial version of an EDI X15 mapping/converting tool and study its grammar files.
