D2920Re-cement or Re-bond Crown

2026 Billing Guide · Last reviewed

Re-attaching a crown that has come loose or fallen off the prepared tooth.

What This Code Covers

D2920 covers re-cementing or re-bonding a crown that has become loose or completely detached from the tooth. The provider removes old cement from the crown and tooth, cleans both surfaces, and re-cements the crown in place. This is one of the most commonly billed re-cementation codes in general dentistry.

Billing Guide

Bill this code when:

  • An existing crown has come loose or fallen off and is being re-cemented
  • The crown is still in usable condition and fits properly
  • The underlying tooth is intact and does not require additional treatment
  • The re-cementation is performed as a standalone procedure

Do not bill this code when:

  • A new crown is being fabricated. Use the appropriate crown code
  • The crown is damaged and cannot be re-used
  • An inlay, onlay, or veneer came loose. Use D2910
  • The crown needs to be adjusted or repaired before re-cementation (bill adjustment separately if applicable)

Insurance and Denial Prevention

Key Payer Rules:

  • Most plans cover D2920 as a minor procedure at a modest reimbursement
  • Some plans have a frequency limit for re-cementation (e.g., once per tooth per year)
  • If the crown keeps falling off, the payer may question whether a new crown is needed
  • D2920 should not be billed on the same date as a new crown on the same tooth

Common Denials and How to Respond:

  • Frequency limit exceeded → Verify the plan's re-cementation frequency limit. If the crown keeps failing, document the clinical situation.
  • New crown recommended → If the payer suggests a new crown, document that the existing crown is functional and re-cementation is appropriate.
  • Bundled with evaluation → Some payers may bundle D2920 with the evaluation. Document it as a separate procedure.

Frequently Asked Questions

D2920 is a relatively inexpensive procedure. Out-of-pocket costs are usually modest, and most insurance plans cover it. The exact cost depends on the practice and the patient's insurance.

Crowns can come loose due to cement failure over time, decay developing under the crown, eating sticky foods, or grinding habits. If a crown repeatedly comes loose, the dentist should evaluate the underlying tooth for decay or fit issues.

Temporary dental cement is available over the counter for emergency use, but a professional re-cementation is recommended as soon as possible. Improper fit or contamination can lead to decay under the crown.
