CMS to Shutter Common Working File for Eligibility Queries Effective February 1, 2020

Posted on Monday, November 11, 2019 1:57 PM

CMS has been working to move queries related to benefit eligibility from the Common Working File (CWF) and establishing the HIPAA Eligibility Transaction System (HETS) as the only source for benefit eligibility transactions. 

On November 1, 2019, CMS issued notification that, effective February 1, 2020, they will begin revoking access to CWF eligibility transactions HIQA, HIQH, ELGA and ELGH.  Submitters that aggregate transactions for otherwise disparate providers (e.g., clearinghouses, billing services, software vendors, etc.) and have both HETS and CWF based eligibility access should use HETS exclusively. CMS will remove HIQA/HIQH/ELGA/ELGH access for these submitters by revoking role-based access for specific CMS RACF IDs. CMS will revoke access starting with high-volume aggregators. Aggregators that use both HETS and CWF based eligibility should assume they must use HETS only no later than February 1, 2020.
