Summary & Overview
CDT D4341: Periodontal Scaling and Root Planing, Four+ Teeth/Quadrant
Headline: CDT code D4341: Periodontal scaling and root planing for extensive quadrants
CDT code D4341 represents periodontal scaling and root planing involving four or more teeth in a single quadrant — a common, clinically significant procedure for treating moderate to advanced periodontal disease. Nationally, this code matters because it defines scope of care for non-surgical periodontal therapy, influences benefit determination across dental and medical plans, and can affect continuity of periodontal care and preventive maintenance pathways. Key payers addressed include Aetna, Blue Cross Blue Shield, Cigna Health, and UnitedHealthcare. Readers will find a concise policy and billing profile, clinical context, and operational considerations relevant to coverage and coding workflows. The publication outlines common clinical indications linked to this service, typical sites of service, and related procedure codes used before or after definitive periodontal therapy. It provides benchmarks for utilization and coding alignment, summarizes payer coverage patterns, and highlights documentation elements commonly required for claims adjudication. Where input data is incomplete, the report flags missing metadata and specifies "Data not available in the input." This summary is intended for billing managers, dental clinicians, practice administrators, and policy analysts seeking a clear, actionable reference on CDT code D4341 and its role within periodontal care delivery.

Clinical & Coding Specifications
Clinical Context
A patient presents to a dental office for evaluation after reporting bleeding gums, increased pocket depths, and localized mobility in the posterior quadrant. The diagnosis on evaluation is chronic periodontitis with involvement of four or more teeth in a single quadrant. The dentist performs a comprehensive periodontal evaluation (D0180), reviews radiographs, charts pocket depths, and determines that nonsurgical periodontal therapy is indicated. Periodontal scaling and root planing is performed on the affected quadrant, documented as periodontal scaling and root planing for four or more teeth per quadrant using CDT code D4341. Post-procedure instructions are provided, and a follow-up periodontal maintenance visit (D4910) is scheduled to monitor healing and response to therapy.

-
25- Significant, Separately Identifiable Evaluation and Management Service by the Same Dentist or Other Qualified Health Care Professional on the Same Day of the Procedure or Other Service: Use when a distinct evaluation or assessment (for example, a problem-focused oral/facial examination or medical evaluation) is documented on the same day asD4341and meets payer documentation requirements. -
59- Distinct Procedural Service: Use when another procedure performed on the same date is separate and distinct from the scaling and root planing procedure and documentation supports that the services are independent.
