D2630 — Porcelain inlay — three or more surfaces
An inlay is a restoration made outside the mouth and then cemented into a prepared cavity. D2630 is the three-surface version in porcelain.
It is one of nine codes covering inlay. For the procedure itself rather than the code, see the inlay guide; for the code, read on.
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.
What has to be true for D2630 to apply
Extent — three surfaces. By three surfaces the tooth has lost the ridges that brace it from the inside. The restoration is holding the remaining walls apart as much as it is filling a hole, and cusp fracture becomes a real risk over the following years.
Material — porcelain. Porcelain is a fired dental ceramic, chosen because it reflects and transmits light much as enamel does and because it does not stain. It is harder than enamel, so it holds a polish for decades, and brittle, so it depends on the strength of the bond underneath it and on an even bite to avoid chipping. The material is part of the code rather than a choice made afterwards, so D2630 is only the right code if that is what was actually used.
Not to be confused with
D2620 — Porcelain inlay — two surfaces: It covers two surfaces instead of three surfaces.
D2610 — Porcelain inlay — one surface: It covers a single surface instead of three surfaces.
D2650 — Composite inlay — one surface: It covers a single surface instead of three surfaces.
D2651 — Composite inlay — two surfaces: It covers two surfaces instead of three surfaces.
D2630 sits in a group of nine codes in total; the remainder are linked at the foot of this page. Two of these codes on one estimate is not necessarily an error, but it is always worth asking what each line is for.
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.

Questions about D2630
What does dental code D2630 mean?
Read literally, D2630 means porcelain inlay, three or more surfaces — and payers do read it literally.
What is the typical fee for D2630?
Typically $1,085–$2,325 before insurance, depending on local fees and the complexity of the individual case.
How do dental plans handle D2630?
Expect major handling — typically 50%. Submitting an estimate first turns that percentage into a number you can rely on.
What is the difference between D2630 and D2620?
D2620 is porcelain inlay, two surfaces: it covers two surfaces instead of three surfaces. That one difference is the whole distinction; the chair time, the materials and the appointment sequence are the same either way.
Also known as: inlay, indirect restoration, lab-made filling, ceramic inlay, gold inlay.
