D5821 — Interim partial denture (mandibular)
An interim denture is a temporary appliance worn during a transitional period. D5821 is the version for the lower jaw.
One of four interim denture codes. If you are trying to understand the treatment, start with the interim denture guide; if you are trying to understand this line on your estimate, you are in the right place.
The rest of this page deals with the specifics: the requirements written into the code, the usual range of fees, the typical benefit outcome, and how to tell it apart from its closest relatives.
What has to be true for D5821 to apply
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.
Status — interim, not definitive. It is built to function for a limited period while something else is planned or healing, and many plans fold its fee into the definitive restoration if that follows within a few months.
How D5821 differs from its neighbours
D5820 — Interim partial denture (maxillary): It is the upper-jaw version.
D5811 — Interim complete denture (mandibular): It is the same procedure with one word changed: complete rather than partial.
D5810 — Interim complete denture (maxillary): It is the upper-jaw version.
Those three codes and D5821 are the whole group — nothing else describes this procedure. Reviewers compare the narrative against the code rather than the other way round, so the question worth asking is what the notes will say.

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.

It is the entry for interim partial denture, mandibular. A practice cannot use it for anything broader than that, which is what makes the code useful to you.
