D5120 — Complete lower denture (mandibular)
A complete denture replaces all the teeth in one jaw. D5120 is the version for the lower jaw.
One of four complete denture codes. If you are trying to understand the treatment, start with the complete denture guide; if you are trying to understand this line on your estimate, you are in the right place.
Below you will find what this code specifically requires, a realistic price range, the usual benefit handling, and where it stops applying and another code begins.
D5120 in detail
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.
Told apart from the codes it is confused with
D5110 — Complete upper denture (maxillary): It is the upper-jaw version.
D5130 — Immediate denture — upper (maxillary): It is the upper-jaw version.
D5140 — Immediate denture — lower (mandibular): It is the interim version.
Those three codes and D5120 are the whole group — nothing else describes this procedure. The practical point: confirm which of these is going on the claim before treatment, not after. Corrections after submission mean a resubmission, a delay, and occasionally a fee you did not expect.
Every code in this group
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.
