D2930 is the CDT code for a prefabricated stainless steel crown placed on a primary (baby) tooth — a pre-formed metal crown that caps a heavily decayed or damaged baby tooth until it naturally exfoliates. It's reported per tooth and is specific to primary teeth.
Informational only — confirm the official CDT descriptor and your payers' rules independently. This is general guidance, not billing, coding, or clinical advice.
When to Use the D2930 Code
Report D2930 when a child's primary tooth needs full-coverage protection with a prefabricated stainless steel crown. Common indications include extensive decay involving multiple surfaces, a primary molar that can't reliably hold a filling, a fractured baby tooth, developmental enamel defects, or a primary tooth restored with a stainless steel crown following pulp therapy (pulpotomy/pulpectomy).
Pick the code by tooth type: D2930 is for a primary tooth, while D2931 is the same prefabricated stainless steel crown placed on a permanent tooth. It's also distinct from custom lab-fabricated crowns like all-ceramic (D2740) or porcelain-fused-to-metal (D2750), which are full crowns rather than pre-formed metal. Code by what was actually delivered and on which tooth.
Documentation & Clinical Scenarios
Stainless steel crowns on primary teeth are common but still reviewed, so the chart should justify full coverage:
- Tooth number (primary tooth designation) and the reason a crown — not a filling — is needed (multi-surface decay, fracture, post-pulpotomy).
- A diagnosis and, where applicable, a note that pulp therapy was performed and the crown protects the treated tooth.
- Pre-operative radiograph(s) showing the extent of decay or the condition of the tooth.
- A short narrative when the indication isn't obvious from the radiograph alone.
Related work such as a pulpotomy (D3220) is a separate procedure with its own code and is documented and billed separately from the crown.
Insurance & Billing Tips
- Verify the child's coverage first. Many pediatric and dental plans cover stainless steel crowns on primary teeth, but frequency and tooth-eligibility rules vary.
- Check frequency and replacement limits. Plans often pay once per tooth within a set interval; a replacement before that window may be denied.
- Bill associated pulp therapy separately. A pulpotomy or pulpectomy is its own procedure — don't bundle it into the crown.
- Confirm coordination of benefits. Pediatric patients are frequently covered under more than one plan, so verify primary vs. secondary before filing.
- Attach a radiograph when required. Some payers want a pre-operative film showing why full coverage was necessary.
Example Case
A 6-year-old presents with a large cavity on a lower primary molar that has reached the pulp. The dentist performs a pulpotomy and places a prefabricated stainless steel crown to protect the tooth until it exfoliates. The office bills the pulp therapy under its own code and reports the crown as D2930 with the tooth number and a pre-operative radiograph attached. Because benefits were verified beforehand and the documentation supported full coverage, both procedures are paid at the expected level.

Frequently Asked Questions
What's the difference between D2930 and D2931?
Tooth type. D2930 is a prefabricated stainless steel crown on a primary (baby) tooth, while D2931 is the same crown on a permanent tooth. The materials and technique are similar, but the codes are reported by which tooth received the crown — and some plans cover them under different rules — so code by the tooth type actually treated.
Does D2930 include any pulp therapy that was done?
No. If the tooth also received a pulpotomy or pulpectomy, that's a separate procedure with its own code, documented and billed on its own justification. The crown code covers the stainless steel crown itself. Reporting the pulp therapy separately, with its own diagnosis, is the correct way to capture both services.
Will insurance cover a stainless steel crown on a baby tooth?
Often, yes — stainless steel crowns are a recognized, cost-effective restoration for primary teeth, and many plans cover them. Coverage still depends on frequency limits, tooth eligibility, and the patient's specific benefits. Pediatric patients also frequently have dual coverage, so verify primary and secondary plans and any replacement-interval rules before treatment.
Do I need a pre-authorization or radiograph for D2930?
Pre-authorization isn't always required, but many payers want a pre-operative radiograph showing why full coverage — rather than a filling — was necessary. Keep that film and a short narrative in the chart even when a pre-estimate isn't required, in case of a post-payment review. Verifying benefits first lets you give the parent an accurate out-of-pocket estimate.
