About HETS 270/271

HETS allows users to submit HIPAA compliant 270 eligibility request files over a secure connection and receive 271 response files. Submitters must develop or acquire a tool to construct and send 270 eligibility request files and receive and deconstruct 271 eligibility response files in a real-time environment. HETS 270/271 application supports real-time transactions only.  The HETS 270/271 application does not accept batch transactions.
