About D3320 — Root Canal — Premolar (Excluding Final Restoration)

The CDT code D3320 refers to a root canal treatment performed on a premolar tooth, excluding the final restoration. This procedure is indicated when the pulp of the tooth is infected or inflamed, requiring endodontic intervention to save the tooth. Clinical documentation should include radiographs showing the condition of the tooth and any symptoms reported by the patient. Billing notes should specify that the final restoration is not included in this code, as it is billed separately. Reimbursement for D3320 varies by payor and state, with average payments around $740. Some insurance plans may have specific limitations or require prior authorization, so it's essential to verify coverage details before proceeding with treatment.

Reimbursement rates for D3320 vary significantly by state, payor, and provider network. The national average negotiated rate is $740. Data sourced from CMS Transparency in Coverage machine-readable files, updated monthly.
