D2335 is the CDT code for a tooth-colored composite filling that restores four or more surfaces of a front tooth.
- When to use: A composite rebuilds four or five surfaces of an incisor or canine, such as a large fracture across both proximals, the incisal, and the lingual.
- When not to use: A two-surface corner chip is D2331, three surfaces is D2332, and four or more surfaces on a back tooth is D2394.
- Billing note: Carriers downcode D2335 to the surface count the chart documents, so name every restored surface and the clinical reason in the chart.
What D2335 covers
D2335 reports a resin-based composite restoration covering four or more surfaces of an anterior tooth (incisor or canine). The surfaces are drawn from mesial (M), distal (D), facial or labial (F), incisal (I), and lingual (L). A four-surface case might be MIDF or MIDL; a five-surface case is MIDFL. The code includes the material, placement, shaping, and finishing.
It does not cover:
- One-, two-, or three-surface anterior composites. Use D2330, D2331, or D2332, even when the restoration involves the incisal angle.
- Composites on posterior teeth. Use D2391 (one surface), D2392 (two surfaces), D2393 (three surfaces), or D2394 (four or more).
- Veneers (D2960 direct, D2961 indirect resin, D2962 porcelain), crowns, or other indirect restorations, including a case better treated as a veneer or crown.
When to bill D2335
Bill D2335 when an anterior tooth has damage or decay restored across four or more surfaces with composite, such as a large Class IV fracture rebuilt across both proximals plus the facial, incisal, and lingual.
The big change: the incisal angle is out
This is the detail that matters most on D2335, and the one older references most often get wrong.
Before CDT 2024, D2335 was defined as four or more surfaces or involving the incisal angle (anterior). Under that second clause, any restoration touching the corner of a front tooth was reported as D2335 regardless of how many surfaces it involved.
The ADA revised the code effective CDT 2024 and removed the incisal-angle clause. The current definition is four or more surfaces, anterior. The ADA’s coding guidance gives the reason: the incisal angle is not a tooth surface but the junction where the incisal edge meets the mesial or distal surface. A claim reports only surfaces, using M, D, F, I, L, and has no field for an angle.
The surface-count test
D2335 requires four or more distinct surfaces restored in continuity. The incisal is the biting edge and counts as a surface, the way the occlusal does on a back tooth. Because an anterior tooth has only five surfaces, D2335 covers four-surface and five-surface (full) restorations.
- Mesial, incisal, and lingual: three surfaces, D2332.
- Mesial, distal, incisal, and lingual: four surfaces, D2335.
- The whole crown rebuilt across all five surfaces: D2335.
Involvement of the incisal angle tells you nothing about the count. A corner can be part of a two-surface restoration or a five-surface one.
Top reasons D2335 gets denied or repriced
- Incisal-angle over-code. A two- or three-surface corner restoration billed as D2335 is downcoded to the documented surface count. This has been the most common D2335 problem since CDT 2024.
- Surface count not documented. D2335 is the highest-paying code in the family, so carriers scrutinize it. If the chart does not name four or more surfaces, the carrier downcodes or pends for records.
- Should have been a crown or veneer. On a tooth this damaged, some carriers question whether a direct composite was appropriate versus an indirect restoration. A narrative explaining the clinical choice helps.
- Frequency or replacement limits. A large composite replacing a recent restoration on the same tooth can hit replacement limits. Document the clinical failure.
- Posterior code on an anterior tooth, or the reverse. A mismatch the carrier catches against the tooth number. Block D2335 on posterior tooth numbers in the PMS.
Surface designation on the claim
The surface designation is its own field on the claim, and its letter count must match the code:
- D2330 takes one letter.
- D2331 takes two.
- D2332 takes three.
- D2335 takes four or more (MIDL, MIDF, MIDFL).
A D2335 claim with only two or three letters is flagged for code-surface mismatch and downcoded, so the PMS should reject a D2335 entered with fewer than four surfaces. The chart has to support four surfaces too. Loose documentation costs the most on this code, because the gap between the D2335 and D2332 allowables is the largest in the family.
Documentation that supports the claim
The claim needs the date of service, the tooth number (anterior, 6 through 11 or 22 through 27), and a designation listing four or more surfaces.
In the patient record, document:
- The clinical reason: extent of caries, fracture, or failed restoration.
- Each of the four or more surfaces restored, named individually.
- The material used.
- Why a direct composite was appropriate, if the case was large enough that a carrier might expect a crown or veneer.
A note that says “large composite #9” with no surfaces will not hold the code.
D2335 versus the posterior four-surface code
D2335 and D2394 occupy the same spot in their families. The split is tooth position.
- D2335 is a four-or-more-surface composite on an anterior tooth.
- D2394 is a four-or-more-surface composite on a posterior tooth.
The amalgam downgrade that affects posterior composites does not apply to D2335. A large anterior composite pays at the composite allowable, though its size may prompt a crown-versus-restoration question from the carrier.
Example case
A 47-year-old patient fractures tooth 8 in a bike fall, breaking off most of the incisal half. The dentist rebuilds the crown with composite across the mesial, distal, facial, incisal, and lingual surfaces.
Billing steps:
- Verify benefits and confirm anterior composite coverage.
- Place the composite. Five surfaces, M, D, F, I, L: designation MIDFL.
- Submit D2335 with the full designation on the date of service, with a pre-op image and a narrative describing the extent of the fracture.
- The carrier processes at the D2335 allowable. The narrative supports both the surface count and the choice of a direct composite over a crown.
A small corner chip on tooth 9 restored across the mesial and incisal would be D2331, not D2335, even though it involves the incisal angle. Size and surface count separate the two cases.
FAQs
- What's the difference between D2330, D2331, D2332, and D2335?
- Surface count. All four are anterior composite codes: D2330 is one surface, D2331 two, D2332 three, and D2335 four or more. The anterior surfaces are mesial (M), distal (D), facial or labial (F), incisal (I), and lingual (L). The incisal plays the same counting role on an anterior tooth that the occlusal plays on a posterior tooth.
- Doesn't D2335 cover restorations involving the incisal angle?
- Not anymore. The ADA revised D2335 effective CDT 2024 to remove the 'or involving the incisal angle' clause, because a corner is not a reportable tooth surface. D2335 now means four or more surfaces. An incisal-angle restoration is coded by its actual surface count, which is often D2331 or D2332.
- When does a Class IV restoration actually reach D2335?
- When four or more distinct surfaces are restored. A large corner fracture rebuilt across the mesial, distal, facial, incisal, and lingual codes as D2335. A small or moderate corner chip that touches only two or three surfaces is D2331 or D2332, even though it involves the incisal angle.
- Will a plan downgrade D2335 to amalgam?
- No. Alternate-benefit amalgam downgrades apply to posterior teeth, where amalgam was a real alternative. Amalgam was never used on front teeth for esthetic reasons, so anterior composite, including a large D2335, pays at the composite allowable. A large anterior restoration may instead prompt the carrier to ask whether a crown or veneer was the more appropriate treatment.
