On September 16, 2019, CMS published a notice in the Federal Register that it would be extending the prior authorization demonstration project for another year. The extension is limited to those states where prior authorization was in effect for calendar year 2019. The affected states are Delaware, Maryland, New Jersey, North Carolina, Pennsylvania, South Carolina, Virginia and West Virginia, as well as the District of Columbia. The extension will run through December 1, 2020. 

In its notice, CMS indicated that the prior authorization demonstration project is being extended “while we continue to work towards nationwide expansion.”  This strongly suggests that CMS believes the program has met the statutory requirements for nationwide expansion under the Medicare Access and CHIP Reauthorization Act of 2015.  However, CMS indicated that it would use the additional year to continue to test whether prior authorization helps reduce expenditures, while maintaining or improving the quality of care offered to Medicare beneficiaries.

CMS has also updated its CMS Ambulance Prior Authorization webpage to reflect the expansion of prior authorization in the existing states through December 1, 2020.
