D4341 — Scaling & root planing, 4+ teeth per quadrant
Scaling and root planing is the treatment for periodontitis. D4341 is the full-quadrant version.
It is the default code in a group of two, and the one whose fee is normally quoted when this treatment is discussed. Our scaling and root planing guide covers the procedure in depth.
Read on for the conditions this code carries, the money involved, the way a payer is likely to treat it, and a plain comparison against each of the codes it is easily mistaken for.
D4341 in detail
Extent — four or more teeth in the quadrant. Four or more teeth in the quadrant puts this at the full-quadrant end of the pair. The fee assumes the whole segment was treated in one sitting, and a plan will expect charting that shows enough affected teeth to justify it.
Counted — per quadrant. Treating the whole mouth produces four separate line items, and most plans cap how many quadrants they will pay for at one visit.
The nearby codes and how they differ
D4342 — Scaling & root planing, 1-3 teeth per quadrant: It is the same treatment on one to three teeth in the quadrant rather than four or more teeth in the quadrant — the distinction decides which of the two is the correct claim.
That code and D4341 are the whole group — nothing else in the code set describes this procedure. If an estimate lists D4341 and the treatment that follows matches a neighbouring code instead, the office has to resubmit — which delays the payment rather than increasing it.

These codes describe the same broad procedure and differ in one respect each. Each has its own page with its own fee range and coverage notes.

Questions about D4341
What procedure is D4341?
Read literally, D4341 means scaling and root planing, 4+ teeth per quadrant — and payers do read it literally.
What is the typical fee for D4341?
Expect $250–$600. Ask for the number in writing, because the code carries no fee of its own and every practice sets its own.
Is D4341 a covered benefit?
Usually yes, as basic periodontal treatment at typically 50–80% — but coverage turns on your own policy, its annual maximum and any waiting period.
What is the difference between D4341 and D4342?
D4342 is scaling and root planing, 1-3 teeth per quadrant: it is the same treatment on one to three teeth in the quadrant rather than four or more teeth in the quadrant — the distinction decides which of the two is the correct claim. Nothing else separates them, which is exactly why a claim submitted under the wrong one of the two is such a common correction.
