D5721 — Rebase mandibular partial denture
D5721 rebases a lower partial denture.
13 codes describe reline, rebase and tissue conditioning, and this is one of them. What separates it from the other twelve is the subject of this page; the reline, rebase and tissue conditioning guide covers the treatment itself.
The sections that follow deal with the requirements, the fee, the claim, and the neighbouring codes — the last of which is where most of the confusion starts.
D5721 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.
Not to be confused with
D5720 — Rebase maxillary partial denture: It is the upper-jaw version.
D5725 — Rebase hybrid prosthesis: It rebases a hybrid implant prosthesis, replacing the acrylic around its framework.
D5730 — Reline complete upper denture (chairside/direct): It is the upper-jaw version.
D5711 — Rebase complete mandibular denture: It is the same procedure specified for complete mandibular rather than for mandibular partial.
D5721 sits in a group of 13 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.
