Can you bill local anesthesia separately on a dental claim?
Anthem, Delta Dental, MetLife, Aetna and United Concordia all publish the same rule on D9210 and D9215: the local anesthetic is part of the procedure fee and is not payable separately — and Delta, MetLife and Aetna add that it is not billable to the patient either.
The local anesthetic is part of the procedure fee at every carrier that publishes a rule on it — Anthem, Delta Dental, MetLife, Aetna and United Concordia among them — and the rule has two halves that are easy to separate and expensive to separate. The plan does not pay D9210 or D9215 as a separate line, and at the carriers that state the second half — Delta, MetLife and Aetna — the office may not bill the patient for it either on a participating agreement. Regional block and trigeminal division block anesthesia (D9211 and D9212) are a different question with a different answer: Anthem states they may not be a covered service at all, while some dental HMO schedules list them at a $0 copay. There is no measured paid share to report for the local anesthesia codes, because they are not paid as separate lines; the sections below are the carriers' own published rules.
What the carriers' own policies say
Anthem states the rule at its widest, covering the newer delivery methods explicitly:
"The administration of local anesthetic; be it traditional, electronic or buffered etc. - is considered inclusive of (part of) all dental procedures [unless a specific plan allows coverage] and is not eligible for a separate benefit." — Anthem Dental Clinical Policy 09-201, Inhalation and Local Anesthesia (2026)
Delta states the half that matters to the office:
"A separate fee for local anesthesia is not billable to the patient whether standalone or in conjunction with other procedures." — Delta Dental of New Jersey 2023 Participating Dentist Handbook
Not payable by the plan, and — at Delta, MetLife and Aetna, which state it — not recoverable from the patient. Under those participating dentist agreements the line is a write-off wherever it appears.
The rest of the market says the same in its own words. MetLife carries local anesthesia on its never-separately-billable list, alongside non-intravenous conscious sedation and analgesia. United Concordia treats D9215, local anesthesia in conjunction with operative or surgical procedures, as integral to the procedure. Guardian lists local anesthesia among its bundled, not separately billable services. HealthChoice Oklahoma excludes separately billed local or block anesthesia given with a restorative or surgical procedure.
The dental HMO schedules make the same point from the other direction, by pricing it at nothing. United Concordia's Concordia Plus schedule lists D9210 local anesthesia at $0, D9211 regional block at $0, D9212 trigeminal division block at $0 and D9215 local anesthesia with a procedure at $0. MetLife's SafeGuard schedule lists D9210, D9211 and D9215 at $0. Humana's federal EPO lists D9215 as no charge. A $0 copay on a dental HMO is the same statement as a bundling rule on a preferred provider plan: the patient owes nothing for the anesthetic itself, because it was never a separate service.
Blocks are the exception worth flagging:
"Regional and trigeminal block anesthesia may not be a covered service." — Anthem Dental Clinical Policy 09-201 (2026)
Why it depends on the plan
Very little here does depend on the plan, which is what makes it unusual. Anthem's wording leaves the door ajar — "unless a specific plan allows coverage" — but a plan that separately reimburses local anesthesia is rare enough that the safe default is the opposite.
What does vary is the block codes and the enforcement route. Where D9211 or D9212 is not a covered service, the question of whether the patient can be billed for it is a matter of the participating agreement, not the benefit table, and it is answered in the provider handbook rather than the plan summary.
The other thing that varies is what happens when a bundled line is submitted. Some payers deny it silently as part of the primary procedure; others return a non-covered charge message that reads, to an office, like a coverage problem rather than a coding one. Neither result changes the outcome: the line does not pay.
What to do
Do not bill D9210 or D9215 as separate lines on a claim. They will not pay, and where the carrier states it — Delta, MetLife and Aetna do — they cannot be moved to the patient on a participating agreement.
Do not put local anesthesia on a patient estimate as a line item. A patient who sees an "anesthesia" charge on the estimate and a different one on the statement will ask, and the honest answer — it was always inside the restoration fee — is easier given before the appointment.
Keep the local anesthetic separate in your head from the sedation family. D9210 and D9215 are bundled everywhere. D9222, D9223, D9239 and D9243 are conditional benefits with qualifying conditions, time caps and, at some carriers, prior authorization. Verifying "anesthesia" as one thing is how an office ends up quoting a bundled code and missing the one with the cap on it.
Check the block codes against the plan before performing one that will be billed. Anthem's position is that D9211 and D9212 may not be covered at all, and that is a different conversation from bundling.
If a plan genuinely does allow a separate local anesthesia benefit, get it in writing on that plan before you rely on it. The published default at every carrier here is that it does not.
