Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 30520 covers

CPT 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.
