Medicare pays $844.71 for 28307 nationally in the office and $497.34 in a hospital or facility. Local office rates run $740.07–$1,107.22.

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

What 28307 covers

A surgeon or podiatrist cuts and repositions a metatarsal and uses autograft—bone taken from the same patient—to support the correction or reconstruction. The procedure may address a metatarsal deformity requiring a change in bone alignment or length. The graft harvest is included in this service. These operations are generally performed in an operating room, including a hospital outpatient department or ambulatory surgery center.

Choose this code when the operative report supports both a metatarsal osteotomy and use of autograft. Document the metatarsal treated, the reason and manner of the osteotomy, and the graft’s source and use. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same 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 requires documented medical necessity; co-surgeons and team surgery are not permitted.
