NCCI Implements More of SNMMI's Proposed Changes to PTP Edits

June 8, 2021

On June 1, CMS's National Correct Coding Initiative (NCCI) posted several procedure-to-procedure (PTP) edit corrections requested by SNMMI for several of the new and revised CPT codes. These edit corrections are implemented on July 1, 2021, and are retroactive for claims with a date of service to January 1, 2020. Fortunately, the NCCI contractor, Capitol Bridge, implemented many of SNMMI's edits thus far. Unfortunately, these corrections are mainly to the Practitioner file and not the Hospital Outpatient file. The chart below summaries the corrections made thus far.
