What 28108 covers

This service covers operative removal or curettage of a benign bone cyst or tumor in a toe phalanx. An orthopedic surgeon or podiatrist may perform it when a lesion in the toe bone requires surgical treatment. The surgeon identifies the involved phalanx, exposes the lesion, and removes or curettes the affected bone tissue. The code is specific to a lesion in a toe bone; a soft-tissue mass on the toe is a different service.

Select the code by the involved bone and the procedure documented, distinguishing a toe phalanx from a metatarsal or tarsal bone. The operative report should identify the toe and phalanx, describe the lesion and the removal or curettage performed, and support that the target was bone. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures 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. Assistant-at-surgery payment is statutorily restricted; 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.

28108 billing questions

How does this differ from removal of a metatarsal lesion?

This code is for a lesion in a toe phalanx. A lesion in a metatarsal is reported with the applicable metatarsal lesion code, such as 28106 or 28107.

Can this code be used for a soft-tissue mass on a toe?

No. The operative service described here targets a bone lesion in a toe phalanx, not a skin or soft-tissue mass.

Is the related preoperative visit or postoperative care separately included?

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

Should modifier 50 be appended when lesions are treated on both feet?

No. CMS identifies bilateral adjustment as inappropriate for this code. The descriptor or anatomy does not support modifier 50.

How are other procedures in the same session paid?

CMS pays the highest-valued procedure in full and applies the standard multiple procedure reduction to the other procedures. Assistant-at-surgery payment is statutorily restricted, and co-surgeons and team surgery are not permitted.

What operative documentation supports reporting this code?

Document the involved toe and phalanx, the bone lesion treated, and the removal or curettage performed. The record should make clear that the target was in bone rather than soft tissue.

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.
