CDT Code D2980: Crown Repair Billing Guidelines

December 5, 2017

Updated 12/26/25

D2980 is a “crown” repair to a ¾ crown or full crown. It is to repair a material failure(fracture) on any part of the crown.

Billing CDT Code D2980

Decay Below the Crown Margin

If a filling is needed to repair decay below the crown’s margins, report the appropriate amalgam or composite code, including a narrative such as:

“A facial composite was placed below the margin of the crown in the area of facial decay.”

Endodontic Access Closure Through an Existing Crown

For endodontic access closure (through an existing cemented or bonded posterior crown), consider a single surface amalgam (D2140) or composite (D2391) with a narrative to report this type of service if the crown is intact.

These procedures are typically reimbursed at 80% of the payor’s fee.

However, a few payors could require that D2980 be reported for closure of an intentional endodontic access opening made through an existing crown, but this would be rare. 

D2980 was revised to emphasize it is restricted to a materials failure, and opening for the endodontic access is not a material failure.

Do Not Report D2980

Core Build-Ups Without Crown Removal

Do not report D2980 in conjunction with D2950 when the crown has not been removed to place the core buildup.

A core buildup is for retention of the crown and should not be reported if the crown remains in place.

Implant-Supported or Bridge Restorations

Do not report D2980 for crown repair of an implant supported restoration or a fixed partial denture (bridge).

See D6090 and D6980, respectively. 

Inlays, Onlays, and Veneers

Do not report D2980 for the repair of an inlay, onlay, or veneer.

See D2981, D2982, and D2983, respectively.

Frequency Limitations and Reimbursement Considerations

A crown repair (D2980)  may be subject to the five to 10 year limitation for a replacement crown, and if performed, may limit the replacement of that crown by the same term.

If reimbursed, the amount may be 50% of the payor’s fee.

D2980 may not be billable to the patient for the first 12-24 months after initial placement, depending on plan processing criteria.

Documentation Requirements

Accompanying clinical documentation should describe the crown repair procedure.

The fee reimbursed may be based on the time necessary to perform the service and amount of the laboratory bill, if applicable.

It is suggested that the time spent be included in the documentation, and a copy of the laboratory bill be attached.
