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

What 30540 covers

This operation opens a congenital obstruction at the back of the nasal passage using an intranasal route. Choanal atresia may present in a newborn or infant with impaired nasal breathing or feeding; the surgeon removes or reshapes the obstructing tissue to establish an airway. An otolaryngologist typically performs the repair in an operating room, with the operative report identifying the atresia and documenting the intranasal approach and work performed.

Choose 30540 when the repair is performed intranasally; the transpalatal approach is represented by 30545. The documentation should support the diagnosis, surgical route, and repair rather than a separate procedure for another nasal condition. CMS assigns a 90-day 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 others are subject to the standard 50% reduction. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted. Modifier 50 is inappropriate for this code.
