D7941 — Osteotomy — mandibular rami
D7941 cuts through the vertical part of the lower jaw behind the teeth so that the whole jaw can be moved.
One of ten orthognathic surgery codes. If you are trying to understand the treatment, start with the orthognathic surgery guide; if you are trying to understand this line on your estimate, you are in the right place.
What follows: the specifics built into the number, the money, the benefit treatment, and the line separating it from the codes it is easiest to confuse it with.
What D7941 specifies
Arch — lower. The bone is denser, but there is far less surface area to support anything removable and the nerve running through the jaw limits how aggressive surgery can be.
D7941 against the codes beside it
D7940 — Osteoplasty — for orthognathic deformities: It reshapes the jaw bone to correct a deformity, without cutting it into segments and repositioning it.
D7943 — Osteotomy — mandibular rami with bone graft: It is that same ramus osteotomy with a bone graft added to bridge the gap the movement creates.
D7944 — Osteotomy — segmented or subapical: It cuts out and repositions a block of jaw carrying a few teeth, rather than moving a whole jaw.
D7945 — Osteotomy — body of mandible: It cuts through the body of the lower jaw, forward of the ramus, in order to reposition it.
D7941 sits in a group of ten codes in total; the remainder are linked at the foot of this page. There is no penalty for asking which of these is planned, and there is a real cost to finding out from an explanation of benefits weeks later.

These codes describe the same broad procedure and differ in one respect each. Each has its own page with its own fee range and coverage notes.

What is the difference between D7941 and D7940?
D7940 is osteoplasty, for orthognathic deformities: it reshapes the jaw bone to correct a deformity, without cutting it into segments and repositioning it.
