CMS NCCI edit files (PTP and MUE), release by release
The quarterly procedure-to-procedure (PTP) pairs and medically-unlikely-edit (MUE) unit limits that decide which code combinations and quantities Medicare will pay together.
CMS updates this file quarterly — January, April, July, and October — and occasionally re-posts a quarter mid-stream to fix errors. Each version we ingested is preserved below as its own immutable release.
CMS reorganizes its site often and direct file links break. If a download link below stops working, every release remains available from the official CMS NCCI edit files page.
2026
In effect July 1 – September 30, 2026 (Q3 2026 on this site).
Our methodology documents how every file is parsed, versioned, and verified@if ($isPfs) — the changes pages show the quarter-over-quarter rate movement each release caused@endif.
