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.

Jumps to that code's current NCCI procedure-to-procedure edits and MUE limit.

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.
