NCCI Procedure-to-Procedure (PTP) Edits
PTP edits identify code pairs that should not be reported together because one is a component of the other or because reporting both is otherwise inconsistent with correct coding.

Verified May 23, 2026 · This is the authoritative regulator URL. The summary below is a research aid; the linked source controls.
The NCCI PTP edits are pairs of HCPCS/CPT codes that should not be reported together. Each edit has a Column 1 code and a Column 2 code. When both are reported for the same beneficiary on the same date of service by the same provider, Medicare denies the Column 2 code (or reduces payment).
Each PTP edit carries a Modifier Indicator:
- 0: no modifier override allowed.
- 1: modifier override allowed when clinically justified (typically 59, X{EPSU}, 25, RT/LT, F/T digit modifiers).
- 9: edit deleted (historical record only).
PTP edit rationale falls into categories: standards of medical/surgical practice; CPT manual or CMS coding instructions; HCPCS/CPT code definitions; mutually exclusive procedures; sequential procedures; gender-specific procedures; CPT separate-procedure rules; family of codes.
The edit files are published quarterly. Practices billing Medicare should reconcile their charge master and EHR encounter forms against the current quarter's edits — particularly for high-volume code combinations in their specialty. Most billing software performs the lookup automatically; the policy understanding behind the edit still belongs to the billing team.
