CPT® Code 42335

The CPT® Code 42335 refers to a surgical procedure known as sialolithotomy, specifically targeting the submandibular (submaxillary) salivary gland or duct. This procedure is categorized as complicated and is performed intraorally, meaning it is conducted within the mouth. The primary objective of a sialolithotomy is to remove a calculus, which is a stone-like formation that can obstruct the salivary gland or duct, leading to pain, swelling, and potential infection. The term 'sialolithomy' is often used interchangeably with sialolithotomy, although the former may refer to a more general procedure. In this complicated version of the procedure, the calculus is typically located in a challenging position that necessitates more extensive surgical dissection. This may involve navigating around critical anatomical structures, such as nerves and blood vessels, to safely access and remove the calculus. The procedure begins with the identification and protection of the papilla of the salivary duct associated with the affected gland. Following this, an incision is made in the mucosa over the duct or gland to expose the area where the calculus is lodged. The surgeon then carefully incises the duct or gland, dissects the calculus free from the surrounding tissue, and subsequently repairs the duct or gland along with the overlying mucosa using sutures. This meticulous approach is essential to ensure the integrity of the salivary system and to minimize complications during recovery.
