The Administrative Transport to Health Plan Transaction will be used as the transport for administrative transactions between a provider and a health plan. Examples include a pharmacy obtaining health plan eligibility, and a physician requesting referral or authorization information from a health plan. This construct is based on the CAQH Phase II CORE #270 Connectivity Rule v2.0.0, which addresses the message envelope metadata, the message envelope standards, and the submitter authentication standards for administrative transactions, as well as communications-level errors, and acknowledgements.
