Summary & Overview
CDT D2330: Resin-Based Composite Restoration, One Surface Anterior
CDT code D2330 represents a resin-based composite restoration for a single surface on an anterior tooth, a common restorative dental procedure that preserves tooth structure and aesthetics. Nationally, this code is relevant across general and specialty dental practices because it captures routine anterior restorations used for caries repair, trauma, and cosmetic needs. Coverage and coding clarity for D2330 influence clinical documentation, claimant adjudication, and payer-provider billing workflows.
Major payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare. Readers will find an overview of payer coverage considerations, typical sites of service, and clinical context for use of D2330. The publication outlines common billing relationships to related restorative CDT codes, typical clinical indications, and common modifiers used alongside restorative codes. It also highlights areas where coding consistency matters for claims processing and clinical documentation.

Billing Code Overview
CDT code D2330 denotes a resin-based composite restoration for one surface on an anterior tooth. This procedure is categorized under Dentistry and typically occurs in a dental office (POS 11). The code describes placement of a tooth-colored, resin-based filling material to restore form and function of a single surface on a front tooth.
Clinical & Coding Specifications
Clinical Context
A 28-year-old patient presents to a dental office with localized dental pain and sensitivity on an anterior tooth. Clinical examination identifies a single-surface carious lesion on a maxillary central incisor. After diagnosis, the dentist administers local anesthesia as needed, removes decay, prepares the enamel-dentin margins, isolates the tooth with cotton rolls or a rubber dam, and places a resin-based composite restoration on the affected single anterior surface. The procedure is completed with finishing and polishing; post-operative instructions are given and recall or restorative monitoring is scheduled.

CDT code:
D2330— Resin-based composite - one surface, anterior -
Common Modifiers:
-
22— Increased Procedural Services: Use when work required to complete the procedure is substantially greater than typically required forD2330(for example, extensive caries removal or unusually difficult access) and documentation supports the additional work. -
52— Reduced Services: Use when the service provided is less than described forD2330(for example, the restoration is limited in scope due to patient tolerance or unforeseen clinical limitation) and documentation supports the reduced service.
