What 30920 covers
This operation ties off the internal maxillary artery, a major arterial supply to the nasal region, to control severe epistaxis. It is generally performed by an otolaryngologist in an operating room when bleeding requires surgical arterial control. The operative record should identify the vessel treated, the approach, and the bleeding problem that led to surgery; the code is not selected simply because epistaxis was present.
Report 30920 for the internal maxillary artery ligation actually performed, distinguishing it from ligation of a nasal or sinus artery and from direct control of bleeding. CMS assigns a 90-day major-surgery global period, including 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 50% multiple-procedure reduction. Modifier 50 is inappropriate for this service. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

- 30905 reports direct control of posterior epistaxis. 30920 reports surgical ligation of the internal maxillary artery.
- 30906Nosebleed control
- 30906 is for subsequent direct control of posterior epistaxis. It is not the code for internal maxillary artery ligation.
30920 billing questions
How is 30920 distinguished from 30915?
Choose based on the artery and procedure documented in the operative report. 30920 concerns internal maxillary artery ligation; 30915 describes ligation of a nasal or sinus artery.
Can 30920 be reported with posterior epistaxis control?
30905 and 30906 describe direct control of posterior nasal bleeding, whereas 30920 reports surgical ligation of the internal maxillary artery. Code the service performed rather than reporting both for the same work.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can modifier 50 be used for bilateral treatment?
No. The anatomy and descriptor make modifier 50 inappropriate for 30920.
Can an assistant or co-surgeon be reported?
Medicare does not pay an assistant at surgery for this code. Co-surgeons and team surgery are not permitted.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full; other procedures in that session are subject to the standard 50% multiple-procedure reduction.
