What 42160 covers

This service destroys a lesion on the roof of the mouth or uvula, using a method such as laser or cautery. Otolaryngologists and oral surgeons may perform it in an office or operating room when the treatment plan is to destroy the lesion rather than remove tissue for examination or excise it surgically. The site and treatment method distinguish this service from biopsy and excision codes for the same area.

Document the lesion’s location and the destruction performed. The code has a 10-day global period, so related postoperative visits during that period are 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 50% multiple-procedure reduction. Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documented medical necessity; 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.

How to choose

42100Palate biopsy
42100 is for biopsy of the roof of the mouth. Report 42160 when the lesion is treated by destruction rather than sampled for examination.
42104Palatal excision
42104 describes excision of a palate lesion. Use 42160 for a destruction method such as laser or cautery, not surgical removal.
42106Palate excision
42106 is another palate-lesion excision option. The key distinction is excision of tissue versus destruction of the lesion with 42160.

42160 billing questions

When should this code be chosen over a palate biopsy code?

Use this code when the lesion is destroyed, for example with laser or cautery. A biopsy code describes tissue sampling for examination.

How does this differ from palate lesion excision?

This code represents destruction of the lesion. Choose an excision code when the service removes the lesion surgically rather than destroying it.

Are related postoperative visits separately reported?

Related postoperative visits during the 10-day global period are included in this procedure’s payment.

How are other procedures performed in the same session paid?

The highest-valued procedure is paid in full; other procedures in the session are subject to the standard multiple-procedure reduction.

Can modifier 50 or an assistant-at-surgery claim be used?

Modifier 50 is inappropriate for this service. Assistant-at-surgery payment requires documentation of medical necessity.

Can co-surgeons or a surgical team report this service?

Co-surgeons and team surgery are not permitted for this code.
