D2620 — Porcelain inlay — two surfaces
An inlay is a restoration made outside the mouth and then cemented into a prepared cavity. D2620 is the two-surface version in porcelain.
nine codes describe inlay, and this is one of them. What separates it from the other eight is the subject of this page; the inlay guide covers the treatment itself.
Everything on this page is about the code itself — its conditions, its fee, its benefit handling, and the precise point at which it stops applying and a neighbouring code starts.
The conditions built into D2620
Extent — two surfaces. At two surfaces the cavity has broken through the side wall, so a band or matrix has to be placed around the tooth to give the material a shape to set against. That step is the real difference in chair time.
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 D2620 is only the right code if that is what was actually used.
How D2620 differs from its neighbours
D2610 — Porcelain inlay — one surface: It covers a single surface instead of two surfaces.
D2630 — Porcelain inlay — three or more surfaces: It covers three surfaces instead of two surfaces.
D2650 — Composite inlay — one surface: It covers a single surface instead of two surfaces.
D2651 — Composite inlay — two surfaces: It specifies tooth-coloured composite resin rather than porcelain.
D2620 sits in a group of nine codes in total; the remainder are linked at the foot of this page. Where the codes sit this close together, the record of the appointment is what settles which one was earned. That is worth knowing before treatment rather than after.
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 D2620
D2620 — what is it?
D2620 records porcelain inlay, two surfaces — one of the restorative codes.
How much does D2620 cost?
Typically $940–$2,020 before insurance, depending on local fees and the complexity of the individual case.
How do dental plans handle D2620?
Expect major handling — typically 50%. Submitting an estimate first turns that percentage into a number you can rely on.
What is the difference between D2620 and D2610?
D2610 is porcelain inlay, one surface: it covers a single surface instead of two surfaces. Apart from that, the two describe the same treatment — which is why the notes for the visit matter more here than the code itself.
Also known as: inlay, indirect restoration, lab-made filling, ceramic inlay, gold inlay.
