The production endpoint queries to determine patient eligibility through an X12 270 request. It formats the request in JSON for an Eligibility status HTTP query for a patient. It receives an EDI 271 response, which is translated to JSON as the response body. It makes this popular EDI transaction more accessible to developers and to users’ applications. We manage the X12 standards in the background and give you efficient access to medical subscriber or dependent plan membership, copays, co-insurances, deductibles, and more, in an easy-to-use and human-readable format.
