What 28740 covers
An orthopedic or podiatric surgeon fuses one midtarsal or tarsometatarsal joint to reduce painful motion and stabilize the foot. The operation typically prepares the joint surfaces for bone healing and holds the bones in position with fixation. Common clinical settings include operative treatment of arthritic or unstable midfoot joints, including a single tarsometatarsal joint. The service is generally performed in a hospital or ambulatory surgery center.
Report this code when the operative documentation supports fusion of one joint in the midtarsal or tarsometatarsal region. A fusion involving multiple joints or a transverse fusion is distinguished from this single-joint service. The procedure has a 90-day global period, which includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 identifies a bilateral procedure, paid at 150%. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is not permitted.
