About 28555: Open talotarsal dislocation repair

Report open surgical repair of a talotarsal joint dislocation, including internal fixation when performed, rather than closed treatment of the dislocation.

This code describes open surgery to reduce a dislocation at the talotarsal joint. The surgeon exposes the joint to restore alignment and may use internal fixation to maintain the reduction. Orthopedic foot and ankle surgeons typically perform the procedure in a hospital or ambulatory surgery center when the injury requires operative treatment.

Select the code based on the documented joint and open approach, not merely the presence of fixation. The operative report should identify the talotarsal dislocation, describe the open reduction, and document any fixation. 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% reduction. Modifier 50 receives bilateral payment at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.

28555 billing questions

How is this code different from 28540?

Code 28555 describes open treatment of a talotarsal joint dislocation. Code 28540 is for closed treatment of a talotarsal dislocation without anesthesia.

Is internal fixation separately reported?

Internal fixation used to treat the dislocation is included in this open-treatment service. Document the reduction and any fixation in the operative report.

What documentation supports reporting this code?

Document the talotarsal joint involved, the dislocation, the open surgical approach, and the reduction performed. Include fixation details when fixation is used.

How does the 90-day global period affect postoperative care?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team-surgery payment is not permitted.

How are other same-session procedures paid?

The highest-valued procedure is paid in full, and other procedures performed in the same session are subject to the standard multiple-procedure reduction.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
