Salivary gland surgery
About 42340: Complicated salivary stone removal
Reports operative removal of a salivary stone when the procedure is complicated, with the gland, approach, and operative complexity documented.
An otolaryngologist or oral and maxillofacial surgeon may remove a salivary calculus that obstructs a duct or gland and causes symptoms such as painful swelling, often around meals. The stone may involve a submandibular, sublingual, or parotid gland. This code represents the complicated procedure in the salivary-stone removal family; the operative report should identify the stone location, surgical approach, and features supporting the documented complexity.
Select this code when the performed stone-removal procedure meets the complicated level, rather than the uncomplicated service represented by 42330. The code has a 90-day global period: the day-before preoperative visit and related postoperative care during that period are included. For multiple procedures in one session, Medicare pays the highest-valued procedure in full and applies the standard reduction to the others. When performed bilaterally with modifier 50, payment is at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
