What 28665 covers
This service treats a dislocated joint between the phalanges of a toe by closed reduction, without opening the joint for surgical repair. It is distinct from treatment of a metatarsophalangeal dislocation at the base of a toe. Orthopedic physicians, podiatrists, and other clinicians qualified to manage toe injuries may perform the reduction in an emergency department, office, or operating or procedure room, depending on the circumstances and need for anesthesia.
Report the code when the treated joint is interphalangeal and anesthesia is required for the closed treatment. The record should identify the affected toe and joint, document the dislocation and closed reduction, and support the anesthetic requirement. Related postoperative visits during the 10-day global period are included. 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 is inappropriate. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.

Related postoperative visits for 10 days are included in the global period for this minor procedure.
Can modifier 50 be used when more than one toe is treated?
