Regulatory Release Summary

CMS released Version 32.3 of the National Correct Coding Initiative (NCCI) edits. This quarterly release introduces over 1,400 new code pair edits, refines modifier indicator designations for outpatient minor procedures, and adjusts practitioner MUE limits for injectable biologics and chemotherapy administration.
