On April 5, 2011, the Centers for Medicare & Medicaid Services (CMS) issued an alert providing information pertaining to the upgrade of Query Files and HIPPA Eligibility Wrapper (HEW) Software to ASC X12 270/271 Version 5010A1 under Section 111 of the Medicare, Medicaid and SCHIP Extension Act (MMSEA). The alert addressed the implementation and scheduled upgrade to the Eligibility Inquiry/Response set used for Section 111 Query Files and the HEW translation software.
This upgrade affects all Section 111 query files exchanged with the CMS Coordination of Benefits Contractor (COBC). Differences between Versions 4010A1 and 5010A1 are minor and adoption of Version 5010A1 should not be difficult. The upgrade to the new version of HEW software (Version 3.0.0) should be completed by January 1, 2012 by all Responsible Reporting Entities (RREs) using the current HEW software. Testing of the new version is recommended but not required.
