What 27870 covers

An orthopedic surgeon exposes the tibiotalar joint, prepares the opposing bone surfaces, aligns the ankle, and stabilizes it to achieve fusion. This operation is commonly performed for advanced post-traumatic or degenerative ankle arthritis, painful deformity, or instability when preserving ankle motion is not the treatment goal. It is typically performed in a hospital or ambulatory surgery setting.

Report 27870 when the operative work is an open fusion of the tibiotalar joint; documentation should identify the joint, open approach, indication, and stabilization performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is paid at 150% for a bilateral procedure. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
