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.
