The HIPAA Eligibility Transaction System (HETS) (CMS-10157)

The Centers for Medicare and Medicaid Services (CMS) is requesting the Office of Management and Budget's (OMB) approval of a revised HIPAA Eligibility Transaction System (HETS) Trading Partner Agreement form. CMS created the HETS application to provide Health Insurance Portability and Accountability Act of 1996 (HIPAA) compliant 270/271 health care eligibility inquiries (270) and responses (271) on a real-time basis. In creating the HETS application, federal law requires that CMS take precautions to minimize the security risk to federal information systems. Accordingly, CMS is requiring that trading partners who wish to connect to the HETS 270/271 application via the CMS Extranet and/or Internet agree to specific trading partner terms as a condition of receiving access to Medicare eligibility information. Applicants will complete the entire Trading Partner Agreement form to indicate agreement with CMS trading partner terms and provide sufficient information to establish connectivity to the service and assure that those entities that access the Medicare eligibility information are aware of applicable provisions and penalties for the misuse of information.

The latest form for The HIPAA Eligibility Transaction System (HETS) (CMS-10157) expires 2023-01-31 and can be found here.
