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

What 31590 covers

An otolaryngologist or head and neck surgeon performs this open neck procedure to restore neural input to a paralyzed vocal fold. The usual technique connects a motor branch of the ansa cervicalis to the distal recurrent laryngeal nerve. It is used for selected cases of vocal fold paralysis, including paralysis after thyroid or other neck surgery, when the clinical plan is to reinnervate the larynx rather than simply medialize the fold.

Report the code for the reinnervation procedure itself, not for laryngoscopic injection or framework medialization performed as a different treatment. The operative report should identify the donor and recipient nerves, the nerve connection performed, and the indication. 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 other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
