Understanding Dental Code D2910

When to Use D2910 dental code

The D2910 dental code is designated for the re-cementation or re-bonding of an inlay, onlay, veneer, or partial coverage restoration. This CDT code is appropriate when a previously placed indirect restoration (such as an inlay, onlay, or veneer) becomes dislodged but is still intact and can be reattached without the need for a new restoration. It is not used for full crowns or bridges; those require different codes. Proper use of D2910 ensures accurate billing and minimizes claim denials.

Documentation and Clinical Scenarios

To support the use of D2910, thorough documentation is essential. Best practices include:

• Clearly noting the type and location of the restoration being re-cemented or re-bonded.
• Describing the condition of the restoration and the tooth (e.g., no new decay, restoration undamaged).
• Documenting the reason for dislodgement (e.g., trauma, debonding, or failure of previous cement).
• Including pre- and post-operative photos or radiographs, if available, to support the clinical necessity.

Common clinical scenarios include a veneer that has come loose due to minor trauma or an onlay that has debonded but remains in good condition. If the restoration is damaged or the tooth requires additional treatment, a different procedure code may be more appropriate.

Insurance Billing Tips

Successful billing for D2910 involves several key steps:

• Verify coverage: Not all dental plans cover re-cementation or re-bonding procedures. Always check the patient’s benefits before treatment.
• Submit detailed narratives: Include a concise description of why the restoration was re-cemented and confirm that no new restoration was fabricated.
• Attach supporting documentation: Upload clinical notes and any relevant images with the claim to reduce the risk of denial.
• Review EOBs: If the claim is denied, review the Explanation of Benefits (EOB) for the specific reason and be prepared to file a claim appeal with additional documentation if necessary.

Remember, D2910 is not intended for use when a new restoration is placed. For new inlays, onlays, or veneers, reference the appropriate CDT codes such as inlay, onlay, or veneer placement codes.

Example Case for D2910

Scenario: A patient presents with a porcelain veneer on tooth #8 that has become dislodged after biting into hard food. The veneer is intact, and the underlying tooth structure is sound. The dentist evaluates the restoration, cleans both the veneer and the tooth, and re-bonds the original veneer using appropriate adhesive protocols.

Billing Steps:

• Document the clinical findings and procedure performed.
• Submit the claim using D2910, with a narrative explaining the veneer was re-bonded, not replaced.
• Attach pre- and post-op photos to support the claim.
• Follow up on the claim and address any insurance requests for additional information promptly.

This approach ensures accurate coding, supports timely reimbursement, and demonstrates compliance with dental insurance standards.
