D2335 is the CDT code for a resin-based composite (tooth-colored) restoration on a front tooth involving four or more surfaces, or the incisal angle — the most extensive anterior composite code, used to rebuild a significant portion of an incisor or canine. It is reported per restoration.
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 D2335 Code
Report D2335 when a front tooth is restored with resin-based composite and the restoration either spans four or more surfaces or involves the incisal angle — the biting-edge corner of an incisor or canine, often after a chip, fracture, or large lesion. The incisal-angle trigger is what makes D2335 distinct: a restoration that rebuilds that corner is reported here even if you might otherwise count fewer surfaces.
Lower anterior composite codes run by surface count: D2330 is one surface, D2331 is two, D2332 is three. D2335 sits at the top of the anterior series. Don't confuse it with the posterior composite series or with amalgam codes (D2161 and others), which use different material and locations.
Documentation & Clinical Scenarios
A D2335 restoration is extensive and visible, so documentation should clearly justify it:
- Tooth number confirming it's an anterior tooth, and the surfaces restored — or that the incisal angle was involved.
- The diagnosis — fracture, chip, large caries, or a failing prior restoration — supporting the extent of the restoration.
- The material (resin-based composite) and the basis for D2335 (four-plus surfaces or incisal angle).
- Supporting photo or radiograph showing the defect, which is especially helpful given the size of the restoration.
Because the incisal angle drives this code, note it explicitly. Report the single D2335 code rather than combining smaller surface-count lines.
Insurance & Billing Tips
- Verify the restorative benefit. Most plans cover anterior composites as a basic service at a coinsurance level after any deductible.
- Anterior composites are usually paid as placed. Front-tooth composites are typically not down-coded to amalgam, since amalgam isn't used on visible teeth — but confirm the plan's rule.
- Document the incisal-angle or four-surface basis. Because D2335 reimburses more than a smaller anterior code, payers may want the supporting note or image.
- Check replacement frequency. Plans commonly limit re-restoration of the same tooth (e.g., once every 24 months).
- Watch the build-up vs. restoration line. A very large front-tooth rebuild may raise whether a crown or other treatment was indicated; clear documentation supports the chosen code.
Example Case
A patient chips the corner of an upper front tooth and the dentist rebuilds the incisal angle with a shade-matched composite. Because the restoration involves the incisal angle, the visit is coded D2335 rather than a lower surface-count code, with a photo on file showing the chip. Because benefits were verified and the incisal-angle involvement documented, the claim is paid at the expected coinsurance with no surprise to the patient.
Patients call about "a big filling to rebuild my front tooth" — not D2335. DentalReception AI answers and books those calls 24/7, captures insurance details for clean intake, and routes clinical and cosmetic questions to your team. See how it handles filling calls, or book a demo.
Frequently Asked Questions
What's the difference between D2335 and D2332?
Extent. D2332 is a three-surface anterior composite. D2335 is used when the restoration involves four or more surfaces or the incisal angle of a front tooth. The incisal-angle trigger is key: rebuilding that biting-edge corner is reported as D2335 even if you'd otherwise count three surfaces, so confirm the angle before coding.
What counts as "involving the incisal angle"?
The incisal angle is the corner where the biting edge of a front tooth meets a side surface. When a restoration rebuilds or extends into that corner — commonly after a chip or fracture of the tooth's tip — the procedure is reported as D2335 regardless of a strict surface count. Documenting that the angle was involved supports the higher code.
Will insurance cover a large front-tooth composite?
Usually yes, as a basic restorative service, since amalgam isn't used on visible teeth and composite is the standard. Deductibles, frequency limits, and annual maximums still apply, and a large restoration may draw closer review. Verifying benefits and attaching a photo before treatment lets you give the patient an accurate estimate.
Do I need a pre-authorization for a D2335 restoration?
Because D2335 is the most extensive anterior composite, a pre-estimate with a photo or radiograph can be worth submitting, especially for a fractured or heavily worn tooth. Verifying the benefit and deductible beforehand — and documenting the incisal-angle or four-surface basis — lets you quote an accurate out-of-pocket amount and supports the claim if it's questioned.
