Medicaid NCCI Edit Files

The complete updated Medicaid National Correct Coding Initiative (NCCI) edit files are posted here at the beginning of each calendar quarter. These data replace the Medicaid NCCI edit files from previous calendar quarters. The presence of a HCPCS/CPT code in a Procedure-to-Procedure (PTP) edit or a Medically Unlikely Edits (MUEs) value for a HCPCS/CPT code does not necessarily indicate that the code is covered by any state Medicaid program or by all state Medicaid programs. States cannot use the files here for processing and paying Medicaid claims.

How to Access the Files

This page provides links to NCCI Edit data on Data.Medicaid.gov, where you can filter, sort, share, and download the data. To download data as an Excel file, first follow the links on this page to navigate to your dataset. Select the “Export” button in the top right of the data, then select “CSV for Excel” from the download list.
