D3353 — Apexification — final visit
D3353 is the visit that fills and seals the canal once an immature root has finally formed a barrier at its tip, ending a treatment that has run for months.
One of four apexification and pulpal regeneration codes. If you are trying to understand the treatment, start with the apexification and pulpal regeneration guide; if you are trying to understand this line on your estimate, you are in the right place.
What follows: the specifics built into the number, the money, the benefit treatment, and the line separating it from the codes it is easiest to confuse it with.
The specifics of D3353
Counted — per visit rather than per tooth or per site.
Told apart from the codes it is confused with
D3352 — Apexification — interim medication replacement: It is the interim version.
D3351 — Apexification — initial visit: It is the same procedure with one word changed: initial rather than final.
D3355 — Pulpal regeneration — initial visit: It is the first visit of pulpal regeneration, where an immature tooth is disinfected and a scaffold placed so the root can carry on growing.
Those three codes and D3353 are the whole group — nothing else describes this procedure. A single word separates several of these codes, and a payer reads that word literally. If the record does not support D3353 specifically, the claim comes back — usually repriced to whichever neighbouring code the reviewer thinks was actually performed.
