The CMS supports the currently mandated version of the transaction based upon the currently mandated version of the ASC X12 Standards for Electronic Data Interchange Technical Report Type 3--Health Care Eligibility Benefit Inquiry and Response (270/271), both of which were adopted as the National standard for the health care eligibility benefit inquiry and response under the Health Insurance Portability and Accountability Act of 1996 (HIPAA). The technical report 3 is also known as a TR3 or implementation guide (IG). (Refer to chapter 24 for current versions adopted under HIPAA.)
