Summary & Overview
CDT D2392: Post 2 Surface Resin-Based Composite
CDT code D2392 represents a posterior dental restoration using a resin‑based composite placed on two surfaces of a tooth. This restorative procedure is commonly performed in dental offices and is a routine element of oral health care, addressing caries, fractures, and other structural tooth damage. Nationally, accurate coding for multi‑surface composite restorations affects claims processing, patient cost‑sharing, and reporting of dental service utilization.
Major commercial payers referenced include Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare. Coverage policies and coding guidance from these payers influence reimbursement pathways and prior authorization practices for restorative dental services.
Readers will find a concise explanation of the clinical indication and procedural scope of D2392, comparisons to closely related CDT codes for single and multi‑surface composite restorations, and a summary of payer coverage considerations and common claim modifiers. The publication also outlines typical sites of service and clinical contexts in which the code is used. If specific fee schedules or payer policy details are sought, note that payer policies vary and plan‑level information is required for precise reimbursement figures.
Billing Code Overview
CDT code D2392 describes a post 2 surface resin‑based composite, a dental restorative service used to repair or restore posterior teeth with two surfaces affected by decay or damage. The procedure involves placement of a tooth‑colored resin composite material to rebuild the tooth structure and restore function and esthetics.
Service Type: Dental restorative service
Typical Site of Service: Dental Office (POS 11)
Clinical & Coding Specifications
Clinical Context
A 42-year-old patient presents to a dental office with a symptomatic posterior tooth diagnosed with dental caries and a failing or previously placed post and core. After clinical and radiographic evaluation, the dentist determines the tooth requires replacement of an existing post using a resin-based composite material that restores two surfaces. The patient is seated in the dental operatory (POS 11). Local anesthesia is administered as needed, the existing restoration and post are removed, the post space is prepared, and a resin‑based composite post reconstruction for two tooth surfaces is placed and contoured. Postoperative instructions are given and appropriate follow-up is scheduled. The workflow involves clinical assessment, radiographic review, removal of previous materials, isolation, placement of the resin‑based composite post for two surfaces (CDT code D2392), occlusal adjustment, and documentation of findings and procedure performed.
