D7241 is the CDT code for the removal of a completely bony impacted tooth that is unusually difficult — most or all of the crown is covered by bone and the case involves complications such as nerve dissection, separate maxillary sinus closure, or an aberrant tooth position. It is the highest-complexity standard impaction code.
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 D7241 Code
Report D7241 when a completely bony impacted tooth is removed and the procedure is unusually complicated by factors that go beyond a routine bony impaction — for example, the need for nerve dissection, a maxillary sinus exposure requiring separate closure, or an aberrant tooth position that significantly complicates removal.
The distinction from the adjacent codes is the documented complication, not the bone alone:
- D7240 — completely bony impaction without unusual complications.
- D7241 — completely bony impaction with documented unusual surgical complications.
- D7230 — partially bony; part of the crown under bone.
D7241 is not a default upgrade for difficult-feeling cases. Without a specific, documented complication, the correct code remains D7240.
Documentation & Clinical Scenarios
D7241 is among the most scrutinized extraction codes, so the complication must be documented explicitly:
- Tooth number and a radiograph (panoramic or CBCT) showing the completely bony impaction.
- A detailed operative narrative naming the specific complication — e.g., proximity to the inferior alveolar nerve requiring dissection, sinus exposure with separate closure, or markedly aberrant tooth position.
- The surgical steps — flap, extensive bone removal, sectioning, management of the complication, and closure.
- Any imaging (such as CBCT) that justified the heightened complexity.
A claim that reports D7241 but documents only a standard completely bony removal will typically be down-coded to D7240.
Insurance & Billing Tips
- Verify benefits first. Confirm impacted-tooth coverage, any waiting period, and the remaining annual maximum.
- Name the complication. D7241 is paid above D7240 only when the operative note specifically documents the unusual complication.
- Provide strong imaging. CBCT or a clear panoramic film supporting nerve proximity or aberrant position strengthens the claim.
- Bill add-ons separately. Sedation, grafts, and membranes are distinct codes, not part of D7241.
- Expect review and appeal. If down-coded to D7240, resubmit with the narrative emphasizing the documented complication.
Example Case
A 27-year-old is referred for a deeply impacted lower third molar whose roots, on CBCT, wrap intimately around the inferior alveolar nerve canal. The tooth #17 is completely encased in bone. During removal, the surgeon raises a flap, removes substantial bone, sections the tooth, and carefully dissects around and protects the nerve before delivering the segments and closing. The procedure is reported as D7241, with the CBCT and an operative narrative specifically documenting the nerve dissection. Because the unusual complication is named and supported by imaging, the claim is paid at the D7241 level rather than down-coded to D7240.

Frequently Asked Questions
What is the difference between D7240 and D7241?
Both remove a completely bony impacted tooth where most or all of the crown is covered by bone. The difference is complexity. D7240 is the standard completely bony removal. D7241 applies only when the case involves unusual surgical complications — such as nerve dissection, a maxillary sinus exposure requiring separate closure, or an aberrant tooth position. The operative narrative must name the specific complication; otherwise the case is coded D7240, and reporting D7241 without documentation invites a down-code.
What counts as an "unusual surgical complication"?
The descriptor points to factors that make the removal unusually difficult beyond a routine bony impaction. Common examples include the need to dissect around the inferior alveolar nerve, a maxillary sinus exposure that requires separate closure, or a markedly aberrant tooth position. The key is that the complication is genuine and documented in the operative note, ideally supported by imaging such as CBCT. A case that simply felt hard, without a defined complication, does not qualify.
Does D7241 include imaging, sedation, or grafts?
No. D7241 covers the complicated surgical removal and closure. Diagnostic imaging (including CBCT), sedation, and any socket preservation graft or membrane are separate procedures with their own CDT codes. Reporting them on the extraction line causes bundling denials, so each is billed separately with its own documentation, which also helps substantiate the complexity of the case.
Does D7241 require pre-authorization?
Because D7241 is a high-complexity code, payers frequently require a pre-treatment estimate and supporting imaging, and they review these claims closely. Verify benefits, confirm any waiting period and remaining maximum, and submit the panoramic film or CBCT with a narrative describing the anticipated complication. Establishing the unusual difficulty in advance reduces the chance of a denial or a down-code to D7240 after the procedure.
