Oral and maxillofacial surgery
About 21046: Mandibular cyst or tumor excision with osteotomy
Reports removal of a benign mandibular cyst or tumor when intraoral osteotomy is required to access and excise the lesion.
This code describes operative removal of a benign cyst or tumor in the mandible when the surgeon must perform an osteotomy through an intraoral approach to reach or remove it. Oral and maxillofacial surgeons commonly perform the procedure for jaw lesions that cannot be managed by simple enucleation and curettage. The operative report should establish the lesion’s mandibular location and explain the osteotomy and excision performed.
Choose this code based on the documented surgical work and approach, not lesion size alone. A simpler enucleation-and-curettage procedure may fit 21040, while an extraoral osteotomy or resection may point to 21047. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple procedure reduction. Modifier 50 is inappropriate for this code. Assistant-at-surgery and co-surgeon payment require supporting documentation; team surgery is not permitted.

21046 billing questions
When should 21046 be selected instead of 21040?
Use 21046 when the operative work requires intraoral osteotomy to access or remove the mandibular lesion. 21040 describes removal by enucleation and curettage without that level of approach.
How does 21046 differ from 21047?
21046 describes the intraoral osteotomy approach. 21047 is the neighboring mandibular code for a lesion requiring extraoral osteotomy and/or resection.
What documentation supports 21046?
Document the benign cyst or tumor’s mandibular location, the intraoral approach, the osteotomy performed, and the excision. The operative note should make clear why simple enucleation and curettage was insufficient.
Can modifier 50 be reported?
No. Modifier 50 is inappropriate for this code; report the service based on the mandibular lesion and work performed.
How does the 90-day global period affect postoperative billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period. Separately reportable care must be outside those included services.
When may an assistant or co-surgeon be paid?
Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.
