What 28600 covers
This service treats a dislocation between the tarsal and metatarsal bones, including injuries in the Lisfranc region. The clinician restores alignment through a closed approach and stabilizes the foot as needed, without anesthesia. Orthopedic clinicians and podiatrists may perform the treatment in an emergency department, office, or facility setting.
Choose this code when the documented tarsometatarsal dislocation is managed closed and without anesthesia; distinguish it from treatment requiring anesthesia or percutaneous fixation. The record should identify the joint injury and support the closed treatment performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and others at 50%. Modifier 50 is inappropriate for this code. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
