What 30520 covers
billing code 30520 describes surgery to correct a deviated nasal septum, generally by reshaping, repositioning, or removing obstructing septal cartilage or bone. Otolaryngologists and facial plastic surgeons commonly perform it for symptomatic nasal obstruction related to septal deviation, including deviation after trauma. The operation may take place in a hospital or ambulatory surgery setting.
Report the service when the operative work addresses the septum itself; document the deviation, symptoms or functional problem, and corrective work performed. A separate inferior turbinate procedure, such as 30140, may be reported when independently performed and documented. The 90-day global period includes 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 others at 50%. Modifier 50 is inappropriate. Assistant-at-surgery payment is statutorily restricted, and co-surgeons and team surgery are not permitted.

- 30140Turbinate reduction
- billing code 30140 addresses the inferior turbinate, not the septum. It may be separately reported with 30520 when both procedures are performed and documented.
- 30540Choanal atresia repair
- billing code 30540 repairs choanal atresia, a congenital posterior nasal passage obstruction; 30520 corrects a deviated septum.
30520 billing questions
When is 30520 used instead of 30420?
Use 30520 for septal correction performed as the septal operation. billing code 30420 describes primary rhinoplasty that includes major septal repair; when that broader operation is performed, the septal work is included in that code.
Can 30520 be reported with inferior turbinate surgery?
It may be reported with 30140 when the surgeon performs a distinct submucous resection of the inferior turbinate in addition to septal correction. Document the separate work; same-session multiple-procedure payment reduction applies.
Should modifier 50 be appended for bilateral nasal obstruction?
No. CMS identifies bilateral adjustment as inappropriate for 30520. The septum is midline, so report the septal repair once rather than as a bilateral service.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. Related routine follow-up during that period is part of the surgical service.
What should the operative documentation establish?
Document the septal deviation and its clinical significance, along with the corrective septal work performed. If another nasal procedure is billed separately, the record should support that distinct procedure as well.
