Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
