What 28540 covers
This code describes closed treatment of a dislocated tarsal bone without manipulation. An orthopedist or podiatrist may manage an acute injury in an office, emergency department, or hospital by immobilizing the affected foot and directing follow-up care. The specific bone and dislocation should be documented; select a more specific code when the injury involves a separately classified joint, such as the talotarsal or tarsometatarsal joint.
Report the code when the clinician provides the definitive closed treatment and does not manipulate the dislocation. The record should identify the injury and affected bone, describe the treatment and immobilization, and support that no manipulation was performed. The service has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
