The Centers for Medicare and Medicaid Services (CMS) released quarterly National Correct Coding Initiative (NCCI) Procedure-to-Procedure  (PTP), Medically Unlikely Edits  (MUE) and Add-on Code  (AOC) edits that take effect July 1. The American College of Radiology® (ACR®) urges practices to review the NCCI edits relevant to radiology and make any necessary updates to their system.

CMS developed NCCI to promote national correct coding methodologies and to control improper coding that leads to inappropriate payment in Medicare Part B claims. This update includes all previous edits and changes from Jan. 1, 1996 to the present.

For more information, refer to the CMS Transmittal 13127, CMS NCCI webpage and the ACR Bulletin or contact Maria Tran, ACR Director of Economic Policy.
