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

What 30420 covers

This service addresses a primary nasal deformity through reconstruction of the nasal framework together with substantial repair of the septum. Plastic surgeons and otolaryngologists commonly perform it in an operating room for patients whose nasal structure requires more than a limited tip or external reshaping. The operative report should identify the deformity, the structures reconstructed, and the major septal work performed; a revision after prior rhinoplasty is classified separately.

Medicare coverage is restricted to specific circumstances, so documentation should support the clinical indication and the reconstructive work. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care for 90 days. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Do not append modifier 50. Medicare does not pay an assistant at surgery for this service, and co-surgeons and team surgery are not permitted.
