What 28104 covers

An orthopedic surgeon or podiatric surgeon uses this service to remove or curette a bone cyst or benign tumor from a tarsal or metatarsal bone. The operative site is bone, not a skin or soft-tissue lesion. The procedure may be performed in a hospital or ambulatory surgical setting; less commonly, it is performed in an office setting. The surgeon’s report should identify the affected bone and describe the lesion removal or curettage.

Report this code for the tarsal or metatarsal site when the procedure does not include bone grafting. If grafting is performed, select the code that describes the grafted procedure instead. Medicare assigns a 90-day global period: the day-before preoperative visit and 90 days of related postoperative care are included. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is 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.

28104 billing questions

Which bone lesions are reported with 28104?

Use it for excision or curettage of a bone cyst or benign tumor in a tarsal or metatarsal bone, without bone grafting. The operative note should identify the bone treated.

How does 28104 differ from 28106 or 28107?

28104 describes removal or curettage without grafting. Choose 28106 or 28107 when the procedure includes the graft type described by that code.

Can the surgeon separately report bone grafting with 28104?

When grafting is part of the lesion procedure, use the applicable graft-inclusive code rather than reporting 28104 and adding the graft procedure separately.

Should modifier 50 be used for lesions on both feet?

No. CMS identifies bilateral adjustment as inappropriate for this code. 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 paid?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is 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.
