Crown Repair Dental Code (D2980): Billing Guide

What D2980 covers

D2980 reports repairing an existing crown that stayed seated on the tooth but lost restorative material. The classic case is a porcelain-fused-to-metal crown where a corner of porcelain fractures off and the dentist rebuilds the contour chairside, or an all-ceramic crown with a chipped incisal edge that gets polished and repaired without removing the crown. The crown is not taken off, not sent to a lab, and not remade. The nomenclature was revised to scope the code specifically to failure of the restorative material.

It does not cover:

• Re-seating a crown that came off intact. That’s D2920 (recement or re-bond crown).
• Remaking the crown. Use the replacement code by material: D2740 (all-ceramic), D2750 (PFM high noble), D2790 (full-cast high noble), and the other D2751/D2752/D2791/D2792 metal-class codes.
• Repairing a bridge (fixed partial denture). That’s D6980.
• Repairing an inlay, onlay, or veneer. Those are D2981 (inlay repair), D2982 (onlay repair), and D2983 (veneer repair).
• Rebuilding tooth structure under a planned crown. That’s D2950 (core buildup).
• A provisional or temporary crown placed while a remake is fabricated. That’s D2799.

D2980 is for fixing a crown that is already on the tooth. Anything that removes, replaces, or re-seats the crown is a different code.

When to bill D2980

Bill D2980 when:

• An existing crown is intact on the tooth but the restorative material has chipped, fractured, or delaminated.
• The dentist repairs the crown in place, chairside, without removing it.
• The repair restores contour, contact, or occlusion, and the crown is left serviceable.

Do not bill D2980 for:

• A crown that came off and gets re-seated. Use D2920.
• A crown that has to be remade because the fracture is too extensive or the tooth structure underneath failed. Bill the replacement crown code.
• Recurrent decay under the crown margin. That is not a material failure and usually drives a remake.
• A bridge, inlay, onlay, or veneer repair. Match the code to the restoration type (D6980, D2981, D2982, D2983).

Repair, recement, or replace

Three procedures sit close together on a crown that has a problem, and the code follows what actually happened to the crown, not how the patient described it on the phone.

• Repair (D2980). The crown stayed on the tooth and lost material. The dentist adds material back or reshapes the existing restoration in place. The crown is never removed.
• Recement (D2920). The crown came off in one piece, is still intact and usable, and gets cleaned and luted back onto the tooth. Nothing is rebuilt.
• Replace (D2740/D2750/D2790 and the other crown codes). The crown is remade because the damage is beyond a chairside repair, the crown no longer fits, or the tooth underneath can’t support the existing crown.

The repair-versus-replace decision is clinical, but it drives the code and the reimbursement. A small porcelain chip that the dentist smooths and rebuilds is D2980. A crown fractured through the metal, or one where the remaining porcelain won’t hold a repair, is a remake and the replacement crown code applies. Billing a repair when the tooth actually got a new crown, or a new crown when only a repair was done, is a code-procedure mismatch that shows up on audit.

Top reasons D2980 gets denied or bundled

1. Warranty bundling on a recently-placed crown. If the same office placed the crown inside the carrier’s lookback window, many plans treat the repair as part of the original crown fee and pay nothing, similar to the global-period rule on recements. The provider contract often prohibits billing the patient for the bundled repair, so check it before charging.
2. Crown-repair exclusion. Some plans don’t list D2980 as a covered benefit at all. The EOB reads “service not a covered benefit,” and the balance is plan-dependent patient responsibility unless the office writes it off.
3. Repair on a crown that should be replaced. Repeated repairs on the same crown, or a fracture large enough that the carrier expects a remake, can draw a denial pushing the case toward the replacement benefit instead.
4. Missing documentation. No photo, no narrative describing what material failed. Carriers reviewing D2980 want to see that the failure was in the restoration, not recurrent decay or a crown that simply came loose.
5. Code-procedure mismatch. D2980 billed on a bridge (should be D6980), on an inlay or onlay (D2981, D2982), or on a crown that was actually recemented (D2920). The mismatch pends or denies.

Documentation that supports the claim

The claim needs:

• Date of service and the correct tooth number.
• A narrative naming the material failure: which surface fractured, chipped, or delaminated, and that the crown was repaired in place rather than removed.
• A clinical photo of the failure before and, ideally, after the repair. Photos are the strongest evidence that a repair, not a remake or a recement, was performed.

For the patient record, document:

• The type of crown being repaired (PFM, all-ceramic, full-cast) and its approximate placement date.
• Whether the office placed the original crown, and whether it falls inside the carrier’s warranty window.
• The nature and extent of the material failure.
• The repair material and technique used, and that occlusion was verified after the repair.

Example case

An established patient presents with the porcelain fractured off the buccal cusp of a PFM crown on tooth #19. The crown is otherwise seated, marginally sound, and the metal substructure is intact. Your office placed the crown four years ago. The dentist repairs the fractured porcelain chairside with a bonded composite and verifies occlusion.

Billing steps:

1. Verify the plan’s crown-repair benefit and confirm the crown is outside the carrier’s warranty window. Four years clears any global period, so a warranty bundle shouldn’t apply.
2. Photograph the fracture before the repair and after the composite is placed.
3. Bill D2980 on the date of service with a short narrative naming the buccal porcelain fracture, the intact substructure, and the in-place repair. Attach the photos.
4. If the plan covers repairs, expect payment at the plan’s allowable for the repair, with any coinsurance or deductible as patient responsibility.
5. If the plan excludes crown repairs, post the denial, confirm the patient-responsibility rules in the contract, and bill the patient the fee if permitted.

If the porcelain fracture had run through the metal or the remaining shell wouldn’t hold a bonded repair, this becomes a remake instead, and the claim carries the replacement crown code rather than D2980.

What to get right in your PMS

1. Code by what happened to the crown. Repaired in place is D2980, re-seated after coming off is D2920, remade is the replacement crown code. The procedure performed decides it, not the chief complaint.
2. Check placement date and provider before billing. A repair on a crown your office placed recently often bundles under warranty and can’t be billed to the patient. Flag it before submission.
3. Attach a photo to the claim, not just the chart. A before photo of the material failure is what separates a payable repair from a “not documented” denial.
4. Don’t double-code the same crown. D2980 and a replacement crown code should not both appear for the same crown at the same visit, and D2980 plus D2920 on the same crown invites a bundling denial.
5. Match the repair code to the restoration. Single crown is D2980, bridge is D6980, inlay and onlay are D2981 and D2982, veneer is D2983. The wrong repair code pends the claim.
