What 42107 covers

An otolaryngologist, oral and maxillofacial surgeon, or other qualified surgeon may use this code to remove a lesion from the palate or uvula and perform complex repair of the excision site. The service may occur in an office or facility setting; the operative record should identify the lesion site, the excision, and the repair performed.

Choose this code when the documented repair is complex, rather than the simpler repair levels represented by sibling codes. The removal and complex repair are reported together, not as separate excision and closure services. Medicare assigns a 90-day global period, which 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% reduction. Modifier 50 is inappropriate. 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.

42107 billing questions

How does this differ from 42106?

42107 is for lesion excision with complex repair; 42106 represents the simple-repair level. The operative note should support the repair level reported.

Can the excision and repair be billed separately?

No. Complex repair is included in 42107; do not report a separate closure service for that repair.

When should 42100 be used instead?

42100 is for biopsy of a palate or uvula lesion. Use 42107 when the service is excision with complex repair rather than a biopsy.

Should modifier 50 be appended for lesions on both sides?

No. CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 should not be used.

What postoperative care is included?

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

Can an assistant or co-surgeon be reported?

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

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.
