Understanding Dental Code D2335

When to Use D2335 dental code

The D2335 dental code is used to report a resin-based composite restoration involving four or more surfaces of an anterior tooth. This CDT code is specific to direct restorations (fillings) where the material used is a tooth-colored composite, and the restoration covers a significant portion of the tooth. Dental teams should select D2335 when a cavity or fracture requires restoration on at least four surfaces (such as mesial, distal, facial, and lingual) of an incisor or canine. Using the correct code ensures accurate claim submission and proper reimbursement.

Documentation and Clinical Scenarios

Accurate documentation is critical when billing D2335. Chart notes should clearly indicate:

• The specific tooth number and surfaces treated
• The extent of decay or fracture necessitating a four-surface restoration
• Pre-operative and post-operative radiographs or intraoral images
• Details of the procedure, including the use of resin-based composite material

Common clinical scenarios for D2335 include large carious lesions extending across multiple surfaces of an anterior tooth, or fractures resulting from trauma. If fewer than four surfaces are restored, consider using D2332 (three surfaces) or D2331 (two surfaces) as appropriate.

Insurance Billing Tips

To maximize reimbursement and minimize denials for D2335, follow these best practices:

• Verify coverage: Confirm patient benefits and frequency limitations for anterior composite restorations during insurance verification.
• Submit supporting documentation: Attach clinical notes and diagnostic images to the claim, especially for extensive restorations.
• Use accurate narratives: Clearly describe the necessity for a four-surface restoration in the claim narrative.
• Review EOBs: Check Explanation of Benefits statements for payment accuracy and reasons for any denials or downgrades (e.g., to amalgam).
• Appeal when necessary: If a claim is denied or underpaid, submit a timely appeal with additional documentation and a detailed explanation of medical necessity.

Staying proactive with insurance verification and documentation helps streamline the accounts receivable (AR) process and supports successful claim outcomes.

Example Case for D2335

Consider a patient who presents with a fractured maxillary lateral incisor (#10) involving the mesial, distal, facial, and lingual surfaces. After clinical examination and radiographic confirmation, the dentist determines a four-surface resin-based composite restoration is required. The dental team documents the findings, captures pre- and post-op photos, and submits a claim using D2335, including a detailed narrative and supporting images. The insurance carrier approves the claim, and payment is posted accurately to the patient ledger, demonstrating effective billing workflow and documentation practices.
