What 28615 covers
This code covers operative repair of a dislocated tarsometatarsal joint, the joint complex commonly called the Lisfranc joint. An orthopedic or podiatric surgeon exposes the dislocation, restores joint alignment, and may stabilize it with internal fixation. The procedure is generally performed in a hospital or other surgical facility when the injury requires open rather than closed or percutaneous treatment.
Report the code when the operative approach is open; fixation performed as part of the dislocation repair is included. The operative report should identify the tarsometatarsal dislocation and document the open reduction and any stabilization. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Bilateral adjustment does not apply. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

28615 billing questions
When should this code be chosen instead of a closed-treatment code?
Use this code when the surgeon performs an open approach to reduce the tarsometatarsal dislocation. Closed treatment and percutaneous fixation are represented by different codes.
Is internal fixation separately reported with this repair?
Fixation performed as part of the open dislocation repair is included. The operative record should show whether and how the joint was stabilized.
Does modifier 50 apply when both feet are treated?
CMS identifies bilateral adjustment as inappropriate for this code, so modifier 50 is not appropriate.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are multiple procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction, at 50%.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be available. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
