Quarterly Update to the National Correct Coding Initiative [NCCI] Procedure-to-Procedure [PTP] Edits, Version 27.3, Effective October 1, 2021


CMS developed the NCCI to promote national correct coding methodologies and control improper coding that leads to inappropriate payment in Part B claims. Version 27.3 will include all previous versions and updates from January 1, 1996, to the present. CMS no longer publishes a mutually exclusive edit file on their website for either practitioner or outpatient hospital services, since all active and deleted edits will appear in the single Column One/Column Two Correct Coding edit file on each website. The edits previously in the mutually exclusive edit file aren’t being deleted but are being moved to the Column One/Column Two Correct Coding edit file. Refer to the CMS NCCI webpage for additional information. Please make sure your billing staff is aware of these updates.
