API

Attachments Submission

The Attachments Submission API supports the X12 EDI 275 Patient Information transaction. It translates this standard to JSON, so it is more accessible to developers for integration into users’ applications.

Attachments submissions take two forms: Solicited and Unsolicited. As an example of an unsolicited attachment, consider workman's compensation claims. Attachments illustrating the conditions giving rise to the claim are required in all worker's compensation claims, hence they called unsolicited claims. Solicited claims usually are sent by payers to providers requesting documentation for a claim.

Submission

Most of our APIs are private and require credentials to gain access. Begin by obtaining your client_id and client_secret for our sandbox test environment.

Interactive

 You can test the APIs from within our interactive documentation, use an application such as Postman, or use your own development platform.

Comprehensive

Change Healthcare supports the following formats for 275 attachments: JPG, BMP, GIF, TIF, TIFF, PDF, DOC, DOCX, TXT, RTF, JPEG, and PNG.
