What 27170 covers
An orthopedic surgeon uses this service to correct a femoral head or neck fracture that has failed to unite or healed in a problematic position. The operation addresses the abnormal bone and may use graft material to support healing; the code includes obtaining the graft. It is typically performed in an operating room, often for a proximal femur fracture that needs reconstruction rather than replacement.
Select this code when the operative treatment repairs a nonunion or malunion at the femoral head or neck, not simply because graft material is used. The operative report should identify the site and healing problem, describe the repair and any grafting, and support the work performed. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued is paid in full and other procedures at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27170 billing questions

Graft procurement is included in 27170. The code covers the repair with or without grafting.
What documentation supports 27170?
Document the femoral head or neck site, the nonunion or malunion, and the operative repair performed. Include grafting details when graft is used.
How is bilateral treatment reported?
CMS lists bilateral reporting with modifier 50, paid at 150%. The code has a 90-day global period.
Can an assistant or co-surgeon be paid?
Assistant-at-surgery payment may be made. Co-surgeons are paid only with supporting documentation; team surgery is not permitted.
