Understanding Dental Code D2920

When to Use D2920 dental code

The D2920 dental code is used when a dental crown needs to be re-cemented or re-bonded to a patient’s tooth. This CDT code specifically applies to situations where an existing crown has become loose or dislodged but is still serviceable and does not require replacement. It is important to note that D2920 should not be used for new crown placements or when a crown is being replaced due to damage or decay. Instead, use this code when the crown itself is intact and only needs to be reattached to restore function and aesthetics.

Documentation and Clinical Scenarios

Proper documentation is essential when billing with D2920. Dental teams should clearly record the reason for the crown’s dislodgement, the condition of the crown and abutment tooth, and the steps taken to re-cement or re-bond the crown. Common clinical scenarios include crowns that have come loose due to trauma, recurrent decay at the margin (if minor and addressed), or loss of cement over time. Always include intraoral photos, radiographs if needed, and a detailed clinical note describing why the crown was re-cemented rather than replaced. This level of detail supports claim approval and reduces the risk of denials.

Insurance Billing Tips

When submitting a claim for D2920, verify the patient’s insurance benefits to confirm coverage for re-cementation procedures. Many plans cover this service, but frequency limitations may apply (e.g., once every 12 or 24 months per tooth). Clearly indicate the tooth number and specify that the original crown is being re-cemented, not replaced. Attach supporting documentation, such as clinical notes and images, to the claim. If the claim is denied, review the explanation of benefits (EOB) for the denial reason and consider submitting a claim appeal with additional documentation. Always check if the patient’s plan has a separate code for re-cementing bridges or other prosthetics, such as D6930 for fixed partial dentures.

Example Case for D2920

Consider a patient who presents with a loose crown on tooth #14. The dentist examines the crown and finds it intact, with no significant decay or damage to the abutment tooth. After cleaning both the crown and the tooth, the dentist re-cements the crown using appropriate dental cement. The clinical note details the patient’s symptoms, findings, and the steps taken. The billing team submits a claim using D2920, attaches the clinical note and intraoral photo, and verifies that the patient’s insurance plan allows for re-cementation once every 12 months. The claim is processed and paid without issue, demonstrating best practices for using D2920 in a real-world scenario.
