What 27703 covers

An orthopedic surgeon, often a foot and ankle specialist, reports this service when surgically revising an existing ankle joint replacement. The operation may address a failed or loose prosthesis and can involve removing and reconstructing around the existing implant. It is typically performed in an operating room, with the operative report identifying the prior replacement and the revision work performed.

Choose this code for revision of an existing ankle replacement, not the initial placement of a total ankle implant. Documentation should describe the implant, the reason for revision, and the components or joint structures addressed. The day-before preoperative visit and 90 days of related postoperative care are included in the 90-day global period. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are paid at 50%. For bilateral services, modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeons and team surgery are not permitted.
