D2330 Resin Composite One-Surface CDT Reimbursement

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.

National Reimbursement Benchmarks

National mean commercial rates for CDT code D2330 center around BUCA (average commercial) at $71.01 versus Medicare which is not provided in the input; using the available values, UnitedHealthcare and Blue Cross Blue Shield show substantially higher mean rates at $108.49 and $98.28 respectively, while Aetna and Cigna Health cluster near $51.31 and $51.17, close to BUCA's lower-mid range.

Rate dispersion (P75 minus P25) varies by payer: UnitedHealthcare (24.8) and Blue Cross Blue Shield (37.4) exhibit the widest spreads, indicating greater variability in allowed amounts; Aetna (13.0) and Cigna Health (16.0) are the tightest.

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.

Related Codes

Code	Description
`D2391`	Resin-based composite - one surface, posterior
`D2140`	Amalgam - one surface, primary or permanent
`D2331`	Resin-based composite - two surfaces, anterior
`D2332`	Resin-based composite - three surfaces, anterior
`D2335`	Resin-based composite - four or more surfaces or involving incisal angle (anterior)

D2391 is an alternative restorative material and location for a one-surface posterior restoration; selected when the lesion is posterior rather than anterior.
D2140 is an alternative material (amalgam) for a one-surface restoration; selected when amalgam is clinically indicated or chosen instead of a resin-based composite.
D2331, D2332, and D2335 represent increasing restoration complexity/size on anterior teeth and are used when the restoration involves two, three, or four+ surfaces (or incisal angle), respectively; these are alternatives when the defect extends beyond a single surface.
Codes commonly used together or as alternatives: D2330 may be chosen instead of D2140 or D2391 based on tooth location and material selection; transition to D2331/D2332/D2335 occurs when the surface count or involvement exceeds one.
