What 42660 covers

An otolaryngologist or oral and maxillofacial surgeon may dilate a narrowed salivary duct to improve saliva flow. The procedure may address stenosis in the parotid duct or a submandibular duct, often associated with obstructive symptoms such as recurrent gland swelling around meals. Code 42660 distinguishes a complicated dilation from a less complex duct dilation; the operative record should make the nature of the added complexity clear.

Select the code based on the procedure performed and its documented complexity, not symptoms alone. Record the duct treated, the narrowing or obstruction, the technique, and the work supporting the complicated level. This is a minor procedure with a 0-day global period, so same-day preoperative and postoperative care is included. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. An assistant is paid only when medical necessity is documented; co-surgeons and team surgery are not permitted.

42660 billing questions

How is 42660 distinguished from 42650?

42660 is for a complicated dilation; 42650 represents the less complex level. Document the procedural details that support the complicated level rather than relying on the diagnosis alone.

Can modifier 50 be reported for bilateral duct dilation?

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

Is same-day postoperative care included?

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

How are other procedures performed in the same session paid?

Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the others are paid at 50%.

Can an assistant or co-surgeon be reported?

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

What documentation supports this code?

Document the salivary duct treated, the narrowing or obstruction, the dilation technique, and the details establishing that the procedure was complicated rather than less complex.

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.
