The National Correct Coding Initiative (NCCI) was implemented to promote national correct coding methodologies and to control improper coding leading to inappropriate payment. This application is intended to provide a means of identifying when certain codes are subject to the automated NCCI prepayment edits.

The National Correct Coding Initiative (NCCI) procedure-to-procedure (PTP) lookup tool is designed to help providers identify when certain codes are subject to the automated code pair edits. Search for coding pairs by entering a procedure code and the performing date(s) of service. The search results display two coding pair lists; refer to the Major-to-Minor and the Minor-to-Major tabs.
