D3332 — Incomplete endodontic therapy; inoperable, unrestorable, or fractured tooth
D3332 is billed when root canal treatment has to be abandoned because the tooth turns out to be unrestorable or fractured.
Of the four codes covering endodontic complications and obstructions, this is the one that appears most often on treatment plans, so it is the figure most people are quoted. For the procedure itself — how the appointments run, how long the result lasts, what the alternatives are — see our endodontic complications and obstructions guide.
This page sets out the conditions the code carries, what practices charge for it, how a plan is likely to assess it, and the named difference between it and each of its neighbours.
Told apart from the codes it is confused with
D3331 — Treatment of root canal obstruction; non-surgical access: It clears a blockage in a canal — a ledge, a calcification, a separated file — without resorting to surgery.
D3333 — Internal root repair of perforation defects: It repairs a perforation in the root from the inside, sealing a hole made by decay, resorption or an instrument.
D3911 — Intraorifice barrier: It places a barrier over the canal openings after root canal treatment, sealing them off from anything above.
Those three codes and D3332 are the whole group — nothing else describes this procedure. These distinctions exist because they change what was actually done. A claim for D3332 when the record describes one of the others is not a technicality — it is the difference between a paid claim and a returned one.

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 D3332
What procedure is D3332?
Read literally, D3332 means incomplete endodontic therapy; inoperable, unrestorable, or fractured tooth — and payers do read it literally.
Is D3332 expensive?
Plan for $300–$900 as the full fee. Two practices a few miles apart can sit at opposite ends of that range for the same work.
Does dental insurance cover D3332?
Expect basic / major handling — variable. Submitting an estimate first turns that percentage into a number you can rely on.
What is the difference between D3332 and D3331?
D3331 is treatment of root canal obstruction; non-surgical access: it clears a blockage in a canal — a ledge, a calcification, a separated file — without resorting to surgery. One does not substitute for the other; if both are listed, ask what each appointment is actually for.
Also known as: blocked canal, separated instrument, root perforation, incomplete root canal.
