What 30115 covers
An otolaryngologist removes an extensive burden of nasal polyps from the nasal cavity using intranasal instruments, often with endoscopic visualization. The service may be performed for clinically significant polyposis, such as multiple or broadly distributed polyps contributing to nasal obstruction. This code addresses nasal polyps, not an unrelated intranasal mass or turbinate tissue.
Select 30115 when the operative note supports extensive rather than simple polyp removal; document the involved nasal areas, extent of disease, approach, and tissue removed. This major surgery has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures at 50%. For bilateral surgery, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.

How to choose
- 30110Nasal polypectomy
- Use 30110 for simple nasal polyp removal. Use 30115 when the operative documentation supports extensive removal.
- 30100Nasal biopsy
- 30100 reports an intranasal biopsy. It is not the therapeutic removal of an extensive burden of nasal polyps.
- 30117Intranasal lesion removal
- 30117 addresses excision or destruction of an intranasal lesion; 30115 is specific to extensive nasal polyp removal.
- 31237Nasal endoscopy
- 31237 describes a surgical nasal or sinus endoscopy service involving biopsy, polypectomy, or debridement. Distinguish it from the extensive nasal polyp excision reported with 30115 based on the documented procedure.
