What 20663 covers

This service establishes femoral fixation for halo traction, in which traction applied through a femoral attachment can help manage severe spinal deformity. An orthopedic or spine surgeon typically performs the procedure in a surgical setting. The code includes removal of the femoral halo component when the traction course is complete; it identifies the femoral application, not cranial or pelvic halo placement.

Report the code when the documented service involves femoral halo fixation, rather than another skeletal traction device or a halo applied at a different site. The record should identify the femoral fixation and its role in the traction treatment. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
