X12N personal health records example
To support ways for the payer community to leverage existing B2B infrastructure while also beginning to work with HL7 CDA R2 and FHIR (in Json or XML), X12 has a draft implementation guide that describes the use of the AXC X12 Patient Information (275) transaction set for the business purpose of transferring Personal Health Record (PHR) information between different health plans.
This example has executable maps to generate an X12 275 transaction with imbedded PHR data in JSON format or extract PHR data from an existing 275 transaction.
