Oral and maxillofacial surgery
About 21045: Extensive malignant mandible tumor resection
Report this service for extensive surgical removal of a malignant mandibular tumor when the operative work requires a broad resection of jaw bone.
An oral and maxillofacial surgeon or head and neck surgeon performs this operation to remove a malignant tumor of the mandible when the required bone resection is extensive. It is typically performed in an operating room as part of cancer treatment. The operative report should identify the tumor site, the extent of mandibular bone removed, and the surgical approach; pathology findings support the malignant diagnosis.
Choose this code based on the documented extent of resection, not simply the tumor’s size or the fact that it is malignant. The less extensive malignant mandible resection code is a closer fit when the operative work does not reach this level. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When other 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. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

21045 billing questions
How is this different from 21044?
Use 21045 when the operative report supports the more extensive mandibular resection. Use 21044 for the less extensive malignant mandible tumor excision.
Can modifier 50 be reported?
No. CMS identifies bilateral adjustment as inappropriate for this code based on its descriptor or anatomy.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.
What documentation supports choosing this code?
Document the malignant diagnosis, mandibular site, and the extent of bone removed. The operative details should substantiate why the resection was extensive rather than the less extensive service.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
