D7471 is the CDT code for the surgical removal of a lateral exostosis — a benign bony outgrowth on the facial (outer) side of the upper or lower jaw. It covers excising and recontouring that bony protuberance, most often along the cheek-side of the premolar or molar regions, when it interferes with function, prosthetics, or comfort.
Informational only — confirm the official CDT descriptor and your payers' rules independently. This is general guidance, not billing, coding, or clinical advice.
When to Use the D7471 Code
Report D7471 when a dentist or oral surgeon removes a lateral exostosis — a benign bony bump on the outer surface of the maxilla or mandible. It is typically indicated when the exostosis interferes with denture or appliance seating, causes recurrent tissue trauma, complicates oral hygiene, or produces discomfort.
Match the code to the type and location of the bone. D7471 is for lateral (buccal/facial) exostoses, not for tori: a torus palatinus (midline of the palate) is reported with D7472, and a torus mandibularis (lingual surface of the lower jaw) with D7473. Simple bone contouring done as part of an extraction or alveoloplasty is not D7471; those have their own codes. Confirm the bone is a true exostosis and that removal is separately indicated.
Documentation & Clinical Scenarios
Bone-removal claims hinge on a clear reason for the surgery, so the chart should establish necessity and location:
- Arch and site (maxilla or mandible, and the region) with a description of the exostosis.
- Size and clinical findings — recurrent ulceration, denture instability, hygiene difficulty, or pain.
- Radiograph(s) — periapical or panoramic — supporting the bony outgrowth.
- A narrative explaining why removal is necessary (e.g., to seat a prosthesis or resolve chronic irritation).
Anything done separately — extractions, soft-tissue grafts, or impressions for a new prosthesis — is documented and billed under its own code rather than folded into D7471.
Insurance & Billing Tips
- Verify benefits and necessity. Some payers cover exostosis removal only when it is functionally necessary (e.g., prosthetic-driven), so confirm the medical-necessity requirement before treatment.
- Use the right bone code. D7471 is for lateral exostoses; tori use D7472 (palatal) or D7473 (mandibular). Mixing these up is a frequent denial reason.
- Don't double-bill with alveoloplasty. Routine bone smoothing during an extraction is generally not separately reportable as D7471.
- Document a clear narrative. Explain the functional problem the exostosis caused; this supports both the claim and any appeal.
- Check per-arch and frequency rules. Confirm how the payer handles bilateral or multi-quadrant bone removal before submitting.
Example Case
A 62-year-old patient cannot wear a new lower partial denture comfortably because a bony ridge on the cheek-side of the mandible repeatedly rubs the prosthesis and causes ulceration. A radiograph confirms a lateral exostosis. The oral surgeon removes and recontours the bone, and the procedure is reported as D7471 with a narrative tying the surgery to seating the prosthesis. Because the documentation established functional necessity and the correct bone code was used, the claim is approved.

Frequently Asked Questions
How is D7471 different from the torus removal codes?
D7471 is for a lateral exostosis — a bony outgrowth on the facial (outer) side of the jaw. The torus codes cover bone in different locations: D7472 is for a torus palatinus (midline of the hard palate) and D7473 for a torus mandibularis (lingual/inner surface of the lower jaw). They describe distinct anatomy, so using the wrong code for the location is a common reason claims are denied.
Is bone smoothing during an extraction billed as D7471?
Generally no. Routine recontouring of bone as part of an extraction or alveoloplasty is reported with the appropriate extraction or alveoloplasty code, not D7471. D7471 is intended for removal of a distinct lateral exostosis that is a separately indicated procedure — not incidental bone smoothing performed in the same surgical field.
Will insurance cover removal of a lateral exostosis?
Coverage varies. Many payers require documented functional necessity — for example, an exostosis preventing a denture from seating or causing chronic ulceration — rather than removal for comfort alone. A narrative explaining the problem, plus supporting radiographs, improves the odds. Verify benefits and any medical-necessity criteria before treatment so the patient understands their responsibility.
Does D7471 require pre-authorization?
A pre-authorization is not always required, but a pre-treatment estimate with the radiograph and a necessity narrative is recommended because bone-removal claims are reviewed closely. Submitting the rationale up front confirms remaining benefits, clarifies whether the payer treats it as a covered functional procedure, and reduces the chance of a surprise balance after surgery.
