Total Ankle Arthroplasty (CPB 0645, reviewed 2026-09-14)
Aetna's Clinical Policy Bulletin 0645 covers total ankle arthroplasty with an FDA-cleared implant for severe ankle arthritis when a set of criteria is met, including at least 6 months of documented conservative care with in-person physical therapy, and covers revision for a failed prosthesis. It treats custom implants, trans-fibular replacement, total talar replacement and intraoperative infection frozen-section analysis as experimental. The source shows a review date of 2026-09-14 but states no effective date, and this is an older source first detected by PolicyChanges on 2026-10-05, so treat it as historical material.
