Simplify your dental coding with CDT companion
When is D2620 used?
The D2620 dental code applies to an inlay, metallic, two surfaces. This CDT code is utilized when patients need a laboratory-made metallic inlay covering two tooth surfaces, commonly for moderate decay or fractures that cannot be fixed with direct fillings but don't need a complete crown. Correct application of D2620 guarantees proper clinical records and payment for the specific restoration treatment provided.
D2620 Charting and Clinical Use
Supporting D2620 usage requires thorough documentation from dental teams. This involves detailed clinical records describing decay or fracture extent, pre-treatment radiographs, and intraoral photographs when available. Treatment plans must clearly explain why direct restorations (like amalgam or composite fillings) are inadequate and why complete crowns aren't needed. Typical clinical situations include:
Substituting failed two-surface amalgam or composite restorations with more lasting inlays.
Fixing teeth with moderate structural loss where crowns would be overtreatment.
Situations where appearance or function needs laboratory-made metallic restorations.
Proper documentation supports claim acceptance and safeguards practices during audits or claim challenges.
Billing and Insurance Considerations
Processing D2620 claims demands careful attention and proactive insurer communication. Follow these guidelines for successful submissions:
Prior authorization: Request pre-approval with supporting materials to confirm coverage and prevent rejections.
Evidence submission: Include radiographs and clinical documentation with claims to show medical necessity.
Benefit coordination: For patients with multiple coverage, coordinate benefits to optimize reimbursement and reduce patient costs.
EOB analysis: Examine Explanation of Benefits statements for payment accuracy and denial reasons.
Claims appeals: When claims are rejected, quickly file appeals with extra documentation and explanations for choosing D2620 as appropriate treatment.
Keeping updated with insurer guidelines and CDT code changes is crucial for reducing outstanding balances and ensuring prompt payment.
How dental practices use D2620
Practice Example: A patient arrives with a broken MOD (mesio-occluso-distal) amalgam on tooth #14. Remaining tooth structure cannot support direct composite restoration but doesn't need full crown coverage. Following clinical assessment and imaging, the dentist suggests a two-surface metallic inlay. Documentation includes pre-treatment photographs, radiographs, and comprehensive notes. The claim uses D2620 with all supporting materials included. Insurance approves payment promptly, showing how complete documentation and proper coding ensure success.
For additional restorative procedures, like D2650 (inlay, resin-based composite, two surfaces), choose codes that align with the material used and clinical circumstances.
Common Questions
How does a noble metal inlay (D2620) differ from porcelain or resin inlays?
Noble metal inlays (D2620) are constructed from precious metals like gold, palladium, or platinum, offering exceptional durability and excellent biocompatibility with oral tissues. In contrast, porcelain inlays are made from ceramic materials while resin inlays use composite materials, each requiring different CDT billing codes. The material selection impacts both treatment longevity and insurance reimbursement, making proper code selection essential for accurate billing.
What patient eligibility criteria or restrictions apply to D2620 coverage?
D2620 coverage depends on individual insurance policies and may include various limitations. Common restrictions include frequency limits per calendar year, coverage limited to posterior teeth only, or benefit downgrades to less costly alternatives such as amalgam or composite fillings. Prior to treatment, always verify patient benefits and review any exclusions, waiting periods, or pre-authorization requirements that may apply.
What is the expected timeframe for D2620 insurance reimbursement?
Processing times for D2620 claims typically range from 2-6 weeks, depending on the insurance provider and submission quality. Complete documentation with proper radiographs, treatment notes, and justification helps ensure faster processing. Claims may be delayed if additional information is requested, so maintaining detailed records and responding quickly to carrier inquiries can significantly reduce reimbursement timeframes.
