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

What 42510 covers

A surgeon redirects parotid duct drainage to change where saliva enters the mouth. The procedure may be considered for persistent, troublesome sialorrhea, including severe drooling associated with neurologic impairment. Otolaryngologists and oral and maxillofacial surgeons typically perform it in an operating room. This code is priced as bilateral, so it represents work on both parotid ducts rather than a separately priced unilateral service.

Report the code when documentation supports diversion of both parotid ducts; record the indication, sides treated, and operative approach. 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 multiple procedure reduction. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
