What 42180 covers

This service covers closure of a short laceration of the palate, such as an acute traumatic wound involving palatal tissue. An otolaryngologist, oral and maxillofacial surgeon, or other qualified clinician may perform the repair in an operating room or another setting equipped for the procedure. The operative record should identify the injured palatal site, document a wound length under 2 cm, and describe the repair performed.

Report the code for the laceration repair itself, not for a biopsy or removal of a palatal lesion. The code has a 10-day global period, which includes related postoperative visits during that period. 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 repair. 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.

42180 billing questions

How does this code differ from 42182?

Use 42180 for a palatal laceration under 2 cm. Check the complete descriptor and documented operative work before selecting 42182 for a different palate repair.

Can a palatal biopsy or lesion excision be reported as this repair?

No. This code describes closure of a laceration; biopsy and lesion excision are different services, even when performed on the palate.

Are related postoperative visits separately reported?

Related postoperative visits during the 10-day global period are included in the procedure's global service.

Should modifier 50 be used for a wound involving both sides of the palate?

No. Modifier 50 is inappropriate for this code; document the laceration and repair performed.

When is an assistant at surgery payable?

Only when the record documents medical necessity for the assistant. 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.
