What 42500 covers

The surgeon repairs a damaged salivary duct to restore the flow of saliva, such as after a duct injury near the cheek or inside the mouth. Otolaryngologists, oral and maxillofacial surgeons, and other surgeons familiar with salivary duct anatomy may perform the repair, commonly in an operating room. The operative report should identify the duct and describe the injury and repair performed.

Report this code for the duct repair itself, not for a procedure that redirects the duct to a different opening. The record should support the need for repair and the work performed. This major surgery code includes 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 50% multiple procedure reduction. Modifier 50 is inappropriate for this code. An assistant at surgery is paid only when medical necessity is documented; 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.

42500 billing questions

How is duct repair different from parotid duct diversion?

Repair restores an injured or disrupted duct. Diversion redirects the duct to a different opening, so select the code that matches the operation documented.

What documentation supports this code?

Document the affected duct, the injury or defect, and the steps taken to restore duct continuity. The operative note should distinguish repair from redirection.

Can modifier 50 be reported?

No. Modifier 50 is inappropriate for this code based on its descriptor and anatomy.

What postoperative care is included?

The major-surgery global period includes the day-before preoperative visit and 90 days of related postoperative care.

Can an assistant surgeon or co-surgeon be reported?

Assistant-at-surgery payment requires documentation of medical necessity. Co-surgeons and team surgery are not permitted for this code.

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.
