D4341: Periodontal Scaling and Root Planing, Four or More Teeth per Quadrant
Definition
D4341 is the CDT code for scaling and root planing (deep cleaning) of four or more teeth with periodontal disease in one quadrant of the mouth.
Why it matters for the front desk
D4341 is billed per quadrant, so a full mouth deep cleaning can be four separate line items. Payers usually want a recent periodontal chart showing pocket depths and x-rays showing bone loss, and many limit it to once per quadrant every two years. Missing charting is a leading reason for denials, so confirm it's attached before the claim goes out.
