CMS Pub. 100-04, ch. 31, § 10.1
Background
This section provides information on Medicare’s implementation of the Accredited
Standards Committee (ASC) X12 Health Care Eligibility Benefit Inquiry and Response
(270/271) transaction (short reference: ASC X12 270/271 eligibility transaction). 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.)

Unofficial copy of government-published law, reproduced from official sources with full provenance. Not an official publication; verify against official sources before relying on it in a filing. Records in the 'guidance' corpus, and only that corpus, are sub-regulatory (interpretive guidelines, survey procedures) and are not binding law. Validity bounds follow each jurisdiction's declared temporalBasis.
