Is my child's baby root canal covered by insurance?

Usually yes. Most plans pay a pulpotomy as a basic service at 70 to 80% on a baby tooth, once per tooth. A pulpotomy (code D3220) is the baby root canal: the infected top part of the nerve is removed and the rest is left in place so the tooth can stay until it falls out on its own.

70 to 80%

Basic service on most pediatric plans

Once per tooth

The plan pays D3220 one time on a given tooth. A second try on the same baby tooth is usually not paid again, whoever does it.

Crown same day

Often followed by a stainless steel crown (D2930) in the same visit. Two codes, two lines, and possibly two different percentages to quote.

Adult tooth trap

On a permanent tooth, many plans pay D3220 only as an emergency step. Bill it and the full root canal from the same office and one denies.

Family max left

Many kids sit on a parent's plan with its own deductible and a family annual max. One check before the visit shows what is actually left.

When D3220 is the right code

  • Usually a baby tooth the child still needs
  • Only the top part of the nerve is removed
  • Root portion of the nerve stays and is kept alive
  • Tooth is being restored the same day or soon after

Documentation payers expect

The X-ray showing the tooth and its root, a note describing the decay reaching the nerve, and the medication placed. If a crown follows, chart it as its own procedure.

D3220 or its neighbors?

D3220
Top of the nerve out, root part stays
D3110
Nerve exposed but left in, covered with medicine
D3230
Whole nerve out of a baby front tooth
D3310
Full root canal on an adult front tooth

Picking the wrong neighbor is its own denial category. The chart decides, not the schedule.

Why baby root canals get denied

Already paid once on that tooth: plans track D3220 per tooth number, so a repeat on the same baby tooth comes back denied. Check history before quoting.
Billed on an adult tooth alongside a completed root canal. Most plans see D3220 as an emergency step and pay one or the other, not both.
Missing the pre-treatment X-ray. Payers want to see decay into the nerve, not just a note that the child was in pain.
Eligibility surprise: the child aged off, the parent changed jobs, or the plan lapsed. A check before the visit catches all three.

What happens after the baby root canal

The pulpotomy is rarely the whole bill. A stainless steel crown (D2930) often goes on the same day and carries its own percentage, and on many plans that crown is basic, not major. Then the tooth needs watching: exams (D0120), X-rays (D0272) and sometimes an extraction (D7140) down the road, each with its own frequency limit on the child's plan. Quoting the family the whole path on day one takes the plan's real numbers, which takes one check.

D3220, quick answers

Does insurance cover a pulpotomy on a baby tooth?

Usually yes, as a basic service at 70 to 80% on most plans, once per tooth.

Is a baby root canal covered on an adult tooth?

Often only as an emergency step. If the same office finishes the full root canal, many plans pay the root canal and deny D3220.

Why is there a second charge for the crown?

The stainless steel crown (D2930) is a separate code with its own percentage. It is billed and paid on its own line, not inside the pulpotomy fee.

Does D3220 need prior authorization?

Rarely, since it is usually done the day the child comes in with pain. The desk needs the plan's basic percentage and remaining max before that visit, not a pre-approval.

Can the plan deny it because of the child's age?

Yes. The child may have aged off the plan, or the plan may limit D3220 to baby teeth. An eligibility check before the visit confirms the child is still active, and the desk can check the code against the plan.
