Orthopedic surgery
About 27846: Open ankle dislocation reduction
Reports operative exposure and reduction of an ankle dislocation, with internal fixation when performed, rather than closed reduction.
The surgeon exposes the ankle joint to reposition a dislocated talus and restore joint alignment. Internal fixation may be used to maintain the reduction when needed. Orthopedic and trauma surgeons typically perform this operation in a hospital operating room, often after an injury that cannot be managed with closed reduction or requires direct operative treatment. The record should establish the dislocation, the open approach, the reduction performed, and any fixation used.
Report this code for the open dislocation treatment, not for a closed reduction performed under anesthesia. Distinguish a separately treated ankle fracture by the fracture pattern and work documented; fracture treatment codes describe a different service. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care for 90 days. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. For bilateral procedures, modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeons require supporting documentation, and team surgery is not permitted.
