What 28102 covers
This service treats a bone cyst or benign tumor in a tarsal or metatarsal bone of the foot. The surgeon exposes the involved bone, removes or curettes the lesion, and fills the resulting defect with the patient’s own bone. Obtaining the autograft is included. Orthopedic foot and ankle surgeons and podiatric surgeons may perform the procedure in a hospital or ambulatory surgical setting.
Select this code when the treated bone is tarsal or metatarsal and the defect is filled with autograft; document the lesion, exact bone, removal or curettage, and graft use. 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 others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon and team-surgery payment are not permitted.
