CPT® Code 42660

The procedure described by CPT® Code 42660 involves the dilation and catheterization of a salivary duct, which is performed to address a narrowing of the duct, known as stenosis or stricture. This condition can impede the normal flow of saliva, leading to discomfort and potential complications. The procedure may be conducted with or without the injection of contrast material, which aids in visualizing the duct during the process. Initially, local anesthetic is administered to the mucosa surrounding the salivary duct to minimize discomfort during the procedure. The technique involves the use of a guidewire that is inserted into the duct's opening, or papilla, and advanced to the area of narrowing. A balloon catheter is then introduced over the guidewire and positioned at the stenotic site. The balloon is inflated and deflated multiple times to achieve the desired dilation of the duct. Following the dilation, contrast material may be injected to confirm the success of the procedure, and radiographs can be obtained to visualize the duct's patency. This comprehensive approach ensures that the salivary duct is adequately treated, restoring normal function and alleviating symptoms associated with the stenosis.
