Otolaryngology surgery
About 30600: Oronasal fistula closure
Repair an abnormal opening between the mouth and nasal cavity, commonly after cleft palate surgery, trauma, or tissue removal.
This operation closes an abnormal passage connecting the oral and nasal cavities. It may be needed for a persistent opening after cleft palate repair or after trauma or removal of tissue. The surgeon identifies the communication and closes it, often using adjacent tissue. Otolaryngologists, plastic surgeons, and oral and maxillofacial surgeons may perform the repair in a hospital or surgical facility, or in an appropriately equipped office setting.
Report 30600 when the documented defect is an oronasal fistula and the service closes that communication. The operative note should identify the oral and nasal sides of the opening and describe the repair. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of 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 requires documented medical necessity; co-surgeons and team surgery are not permitted.

30600 billing questions
How is an oronasal fistula different from a nasolabial fistula?
30600 is for a communication between the mouth and nasal cavity. Use 30580 when the documented defect is a nasolabial fistula.
What documentation supports reporting 30600?
Document the opening's location and its communication between the oral and nasal cavities, along with the closure performed.
Can modifier 50 be used for fistulas on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code.
How does the global period affect postoperative visits?
The 90-day global period includes the day-before preoperative visit and related postoperative care during the 90 days after surgery.
What if another procedure is performed during the same session?
CMS applies the standard multiple procedure reduction: the highest-valued procedure is paid in full, and other procedures are reduced. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
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.
