What 42650 covers

This service widens a narrowed salivary duct using a percutaneous approach. It may be performed when duct stenosis interferes with saliva drainage, such as in a patient with obstructive salivary symptoms. Otolaryngologists and other surgeons who treat salivary duct disorders typically perform it in an office procedure setting or a facility, depending on the case and practice arrangement. The route matters: dilation performed through the mouth is represented by a different code.

Report the service when the physician performs percutaneous duct dilation, and document the treated duct, the access route, the narrowing or drainage problem, and the work performed. The code has a 0-day global period, so same-day preoperative and postoperative care is included. 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. Modifier 50 is inappropriate for this code. Medicare does not pay an assistant at surgery, and co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

42650 billing questions

How is this code distinguished from 42660?

Choose 42650 for a percutaneous approach to dilating the salivary duct. Code 42660 represents dilation performed through an intraoral approach.

What documentation supports reporting this service?

Document the duct treated, the percutaneous route, the stenosis or drainage problem, and the dilation performed.

Is modifier 50 appropriate when both sides are treated?

No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.

Can an assistant surgeon or co-surgeon be reported?

Medicare does not pay an assistant at surgery for this service. Co-surgeons and team surgery are not permitted.

How are other procedures in the same session paid?

When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others are subject to the standard multiple-procedure reduction.

Does the code include same-day postoperative care?

Yes. The 0-day global period includes same-day preoperative and postoperative care.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
