About 28540: Closed treatment of tarsal bone dislocation
Report this service for closed management of a dislocated tarsal bone when the physician treats the injury without manipulating the dislocation.
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.

28540 billing questions

Use 28540 for closed treatment of a tarsal bone dislocation without manipulation. When the documented injury is specifically a talotarsal joint dislocation, compare the codes for that joint.

No. This code describes closed treatment without manipulation; documentation should support that the dislocation was not manipulated.

28540 is for closed treatment without manipulation. Open treatment of a tarsal bone dislocation is represented by 28555.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How is bilateral treatment reported?
When the procedure is bilateral, modifier 50 is paid at 150%.
Can an assistant surgeon be paid for this procedure?
Assistant-at-surgery payment is allowed only when medical necessity is documented. Co-surgeons and team surgery are not permitted.
