D3221 — Pulpal debridement, primary and permanent teeth
D3221 opens a tooth and clears the canals to relieve acute pain, as an emergency step before proper root canal treatment.
This code belongs to a set of three covering pulpotomy and pulpal debridement. The clinical detail lives in the pulpotomy and pulpal debridement guide; the code-level detail is here.
The detail below covers what the code obliges the record to show, the range of fees, the likely insurance outcome, and a comparison drawn code by code.
D3221 in detail
Dentition — a primary (baby) tooth. The restoration only has to survive until the tooth is shed naturally, which changes what counts as adequate treatment and usually rules out the more expensive alternatives.
Where the line falls between D3221 and the rest
D3220 — Therapeutic pulpotomy (excluding final restoration): It removes the inflamed pulp from the crown of the tooth and dresses what is left, the usual treatment for a baby tooth with decay into the nerve.
D3222 — Partial pulpotomy for apexogenesis — permanent tooth with incomplete root development: It is for permanent teeth rather than primary teeth.
Those two codes and D3221 are the whole group — nothing else describes this procedure. The distinction is clinical, not administrative: each of these describes work that was genuinely done differently, and the fee follows the work.

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 D3221
What does dental code D3221 mean?
It is the endodontics code for pulpal debridement, primary and permanent teeth, and it means that specific procedure and no other.
What is the typical fee for D3221?
Between $180–$480 in most practices — and that is the figure before any benefit is applied, not what you would pay at the desk.
How do dental plans handle D3221?
In most cases yes, at the basic rate: typically 70–80%. The annual maximum is what usually decides how much of that you actually see.
What is the difference between D3221 and D3220?
D3220 is therapeutic pulpotomy, excluding final restoration: it removes the inflamed pulp from the crown of the tooth and dresses what is left, the usual treatment for a baby tooth with decay into the nerve. The two are neighbours by number rather than by treatment, so seeing both on a plan usually means both were genuinely planned.
Also known as: pulpotomy, baby root canal, pulpal debridement, apexogenesis, nerve treatment.
