Pediatric Crown CDT Codes: D2929, D2930 and the Rest of the D29 Series

Pediatric crowns sit in a small, tidy block of the CDT Code, but the details trip up front desks every week: which code a zirconia crown takes, whether an esthetic crown on a molar needs a narrative, and what happens when the plan only pays for steel. This guide puts every prefabricated pediatric crown code in one place, with the documentation that keeps claims moving.

The prefabricated crown codes at a glance

The key distinctions are material and dentition. Porcelain/ceramic crowns split into D2929 (primary) and D2928 (permanent). Plain steel crowns split into D2930 (primary) and D2931 (permanent). The esthetic steel options, a resin window (D2933) or a factory coating (D2934), each have their own code, so a pre-veneered steel crown is never a D2930.

D2929: pediatric zirconia crowns

Prefabricated zirconia crowns for primary teeth are reported with D2929, prefabricated porcelain/ceramic crown, primary tooth. Zirconia is a ceramic, and the code covers any primary tooth, anterior or posterior, so the same code applies whether you place a zirconia crown on a central incisor or a second primary molar.

Earlier versions of the CDT Code had no ceramic crown code for primary teeth. If an old practice template still maps zirconia crowns to another code, update it to D2929.

D2930: stainless steel crowns on primary teeth

D2930, prefabricated stainless steel crown, primary tooth is the workhorse code of pediatric restorative dentistry. Use it for any plain steel crown on a primary tooth. It is strictly a primary tooth code: a steel crown on a permanent tooth is D2931.

A Hall technique crown is still a prefabricated stainless steel crown on a primary tooth, which is what the D2930 descriptor describes. The CDT Code does not have a separate code for the Hall technique. Some payers ask about technique or have their own policies, so check before assuming how a plan treats it. Our Hall technique vs. conventional crowns guide covers case selection.

Strip crowns, resin crowns and coated steel crowns

• Strip crowns. A strip crown is a direct composite crown built in a celluloid form, which matches the descriptor for D2390, resin-based composite crown, anterior. D2932 describes a prefabricated resin crown, a different procedure. Confirm how your payers want strip crowns reported.
• Coated steel crowns. Pre-veneered stainless steel crowns on primary teeth are D2934, not D2930.
• Open-face steel crowns. A steel crown with a resin window is D2933.

Codes that often ride along with a crown

Documentation that supports a crown claim

A correct code is only half of a clean claim. These habits cover the rest:

1. Tooth number, every time. Report the primary tooth letter (A through T). Surfaces are not used for full-coverage crowns.
2. Why a crown and not a filling. Record the extent of caries (for example, lesions on multiple surfaces or extending past the line angles), any pulp therapy, developmental defects, or the child's caries risk. Payers commonly list these as indications for a prefabricated crown.
3. Pre-op radiographs and an intraoral photo. They show the extent of decay or breakdown and support the need for full coverage if a payer asks.
4. A short narrative for zirconia, especially on molars. State the clinical reason for full coverage first, then why a ceramic crown was chosen. Payer policies generally exclude crowns placed solely for cosmetic reasons, so lead with the disease, not the appearance.
5. Keep it consistent. The code, tooth number and notes on the claim should match the chart exactly.

When the plan pays for steel, not zirconia

Some dental plans include an alternate benefit (sometimes called least expensive alternative treatment) provision. Under that kind of clause, a plan may pay a D2929 zirconia crown at its D2930 stainless steel allowance, leaving the difference as the family's responsibility. Whether that applies depends entirely on the patient's plan.

• Verify benefits for D2929 and D2930 before treatment, and ask whether an alternate benefit applies.
• Consider a predetermination for multiple zirconia crowns or a full-mouth case.
• Give families a written estimate showing both options. Our guide to explaining zirconia crowns to parents has language for that conversation, and the zirconia vs. stainless steel comparison covers the clinical side.

Medicaid and zirconia crowns

Medicaid coverage for D2929 is set state by state, so there is no single answer to whether Medicaid covers zirconia crowns for kids. Some states list D2929 as a covered benefit for children; others limit coverage or do not cover it at all. Frequency limits also differ from the stainless steel code.

As one example, Nevada Medicaid's fee-for-service dental coverage table (updated September 16, 2026) lists D2929 for recipients under 21 without prior authorization, limited to once in a lifetime per tooth, while D2930 is limited to one unit per 36 months per tooth. Your state will differ, so check your state Medicaid dental provider manual or fee schedule, and your managed care plan if you work with one.
