What 21034 covers
This service covers surgical excision of a malignant tumor involving the maxilla, or upper jaw, or the zygoma, the cheekbone. It is typically performed in an operating room by an oral and maxillofacial surgeon, head and neck surgeon, or another surgeon treating facial bone malignancy. The operative approach and tissue removed depend on the tumor’s location and extent; the code is specific to the malignant tumor site, not simply any procedure on facial bone.
Choose this code when the operative report supports a malignant tumor of the maxilla or zygoma and documents the excision performed. A benign tumor at those sites points to 21030; a malignant mandibular tumor belongs to a different code family. The service has a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this descriptor and anatomy.

How to choose

- 21026Facial bone excision
- Code 21026 describes excision of facial bone more generally. Use 21034 when the documented service is excision of a malignant tumor specifically involving the maxilla or zygoma.
21034 billing questions
How does this differ from 21030?
Both codes concern the maxilla or zygoma, but 21034 is for a malignant tumor. Code 21030 describes excision of a benign tumor or cyst at those sites.
Can I use 21034 for a malignant mandibular tumor?
No. This code is limited to the maxilla or zygoma; a malignant tumor of the mandible is represented by a different code, such as 21044.
What documentation supports reporting 21034?
The operative report should identify the maxilla or zygoma as the tumor site and describe the excision. The record should also support that the tumor is malignant.
Is modifier 50 appropriate for bilateral work?
No. CMS identifies modifier 50 as inappropriate for this descriptor and anatomy.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days.
Can an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
