X12 is a non-profit organization chartered by the American National Standards Institute (ANSI) to develop and maintain business-to-business transaction standards. Several of the X12 Implementation Guides (X12 Type 3 Technical Report (TR3), also known as an X12 Implementation Guide (IG)) have been adopted under HIPAA for use by covered entities in the healthcare and insurance industry. These standards are widely adopted across providers, payers, and technology vendors, such as Change Healthcare. We intend these TR3s and the X12 metadata contained in them to be used in conjunction with Change Healthcare’s APIs, so your organization can access the reference industry standards that include the codes and rules necessary to submit Eligibility, Claims, and Claim Status transactions. To obtain a license that also provides access to the full requirements for these transactions, visit https://x12.org/licensing. We make every effort to ensure consistency between Change Healthcare’s APIs and the X12 TR3. If there is a discrepancy, the X12 TR3 is the final authority.
Use our OpenAPI Spec JSON file as a reference for development. Notes on the data in the following sections include:
- The Constraints column describes the minimum and maximum number of alphanumeric characters that a field entry can occupy: for example, 1/60 R is a Required field with a minimum of one and maximum of 60 characters.
- If a field is required, the Constraints entry notes it.
For the Constraints column in each table, the following letters stand for specific meanings:
- R = Required (must be used if/when the object is part of the transaction);
- S = Situational (may be required depending on how the transaction content is structured).
Situational loops, segments, or elements can be Situational in two forms:
IFa condition is met, but can be used at the discretion of the sender if it is not required (for example, some descriptive notes can be added to a claim if necessary);
IFa condition is met, but if not, the sender must not use it in their request ("Do not send").
