About 28320: Tarsal bone nonunion or malunion repair
Operative repair of a tarsal bone that has failed to unite or healed in poor alignment, typically after prior fracture treatment.
This service addresses a tarsal bone that has not healed or has healed in a position that needs surgical correction. An orthopedic or podiatric surgeon may realign and stabilize the bone, with grafting when needed. Examples include a persistent nonunion or a symptomatic malunion involving a tarsal bone such as the navicular, talus, or calcaneus. These repairs are generally performed in an operating-room setting.
Report 28320 when the operative work treats a tarsal-bone nonunion or malunion, not when the procedure is an osteotomy for another corrective purpose or treatment of an acute fracture. The operative report should identify the bone, the healing problem, relevant prior treatment, and the repair performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For bilateral surgery, modifier 50 is paid at 150%. In a same-session multiple-procedure claim, the highest-valued procedure is paid in full and others at 50%. An assistant at surgery may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.
