April 2026 NCCI edit files now available

CMS published the latest edition of the National Correct Coding Initiative (NCCI) quarterly edit files, which take effect on April 1. Revenue cycle professionals can download the files on the procedure-to-procedure (PTP) edits, medically unlikely edits (MUE), and add-on code edits web pages.

The 3,750-plus new PTP code pairs are, in part, offset by more than 4,800 deleted code bundles. Most of the new code pairs correspond with medicine codes (U codes) and Category III codes (T codes). Six code pairs have been revised.

The NCCI version 32.1 edits also introduce 121 new MUEs and seven revised MUE counts. The MUE file signifies the cap on daily units of service that providers are eligible to report. Effective April 1, providers will be limited to reporting one unit of service for code G0447 (Face-to-face behavioral counseling for obesity, 15 minutes) per date of service, which is a reduction of the two units of service currently available.
