When is D2920 used?
The D2920 dental code applies when an existing dental crown requires re-cementation or re-bonding to a patient's tooth. This CDT code is specifically designated for cases where a previously placed crown has loosened or detached but remains in good condition and doesn't need replacement. D2920 should not be applied for initial crown installations or crown replacements due to structural damage or tooth decay. This code is appropriate when the crown is undamaged and simply needs reattachment to restore proper function and appearance.
D2920 Charting and Clinical Use
Accurate documentation is crucial when using D2920 for billing purposes. Dental professionals must thoroughly document why the crown became detached, assess both the crown and supporting tooth condition, and record all procedures performed during re-cementation. Typical situations include crowns loosened by physical trauma, minor marginal decay (when appropriately treated), or natural cement deterioration over time. Documentation should include intraoral photographs, relevant X-rays when necessary, and comprehensive clinical notes explaining the decision to re-cement rather than replace the crown. Thorough record-keeping helps ensure claim acceptance and minimizes denial risks.
Billing and Insurance Considerations
Before submitting D2920 claims, confirm the patient's benefit coverage for crown re-cementation services. While most insurance plans provide coverage for this procedure, restrictions on frequency may exist (typically once per 12-24 month period per tooth). Clearly specify the affected tooth number and emphasize that the existing crown is being re-cemented, not replaced entirely. Include supporting materials like clinical documentation and photographs with your claim submission. If claims are rejected, carefully review the explanation of benefits to understand denial reasons and prepare appeals with additional supporting evidence. Verify whether the patient's plan uses different codes for re-cementing other restorations, such as D6930 for bridge work.
How dental practices use D2920
A patient visits the office complaining of a mobile crown on tooth #14. During examination, the dentist determines the crown remains structurally sound with no notable decay or damage to the underlying tooth. Following thorough cleaning of both the crown and tooth surface, the dentist re-cements the restoration using suitable dental cement. Clinical records include the patient's chief complaint, examination findings, and detailed treatment procedures. The administrative team files a claim with D2920, includes clinical documentation and photographs, and confirms the patient's insurance permits re-cementation annually. The claim receives approval and payment, illustrating proper D2920 implementation in clinical practice.
Common Questions
Are there specific dental codes for re-cementing bridges and other prosthetic restorations?
Yes, there are distinct CDT codes designated for re-cementing bridges and various dental prosthetics. Code D2920 is used specifically for re-cementing or re-bonding individual crowns. When working with fixed partial dentures (bridges), the correct code to use is D6930 for re-cementing or re-bonding fixed partial dentures. It's essential to select the code that most accurately corresponds to the specific restoration being serviced.
What is the typical insurance reimbursement range for D2920, and are there standardized fees?
Insurance coverage for D2920 fluctuates depending on the patient's specific plan details, your office's negotiated rates, and regional pricing variations. While no universal standard fee exists, typical reimbursement amounts generally fall between $50 and $150. To prevent unexpected costs for patients, it's recommended to verify benefit coverage and review your practice's contracted fee schedule prior to performing the treatment.
Is it possible to bill D2920 when the original crown was placed at a different dental practice?
Yes, D2920 can be properly billed regardless of which dental office originally placed the crown, provided the clinical circumstances justify re-cementation or re-bonding procedures. Ensure thorough documentation of both the crown's condition and the abutment tooth's status. Include comprehensive details about the original placement when available, as certain insurance carriers may require this information for claim processing.
