Release Notes:

v3 Updates (9/20/2021)

Change Healthcare Medical Network APIs support a significant troubleshooting feature called metadata. API users do not need to enable this capability; it is automatic and has no effect on information in any medical transaction. If you encounter any issues with a transaction and need to work with CHC technical support, you can furnish the representative with the values provided in the meta object. This enables the technician to get a head start on addressing the problem.

   "meta": {
       "senderId": "Xxxx.Xxxxxx",
       "applicationMode": "prod",
       "traceId": "bc409414-70ed-e387-e7d8-7addd7a7b599"

The meta object obtains its data from the request headers and the transaction token.

v3 Updates (9/2/2021)

Medical Network APIs are now deployed to an enhanced cloud-native network connection, which offers improved API speed and reliability. We recommend updating your systems to the following API endpoint URLs at the first opportunity::

  • Production:
  • Sandbox:

v3 Updates (03/05/2021)

  • Added two arrays - benefitsRelatedEntities and eligibilityAdditionalInformationList. Each JSON object in benefitsRelatedEntities maps to objects within Loop 2120C. Each JSON object in eligibilityAdditionalInformationList maps to objects in Loop 2115C. Objects in the array will be equal to the number of times the loop repeats. In the future, we will deprecate the legacy benefitsRelatedEntity and eligibilityAdditionalInformation objects because information is already captured in objects that are part of their respective arrays.
