What 27284 covers
An orthopedic surgeon fuses the femoral head and pelvis to eliminate motion at the hip. The operation involves preparing the joint surfaces and stabilizing the bones with fixation; the surgeon may use bone graft as part of the operative plan. Hip fusion is an uncommon salvage choice for severe hip disease when preserving or replacing the joint is not the selected approach, and it is generally performed in a hospital operating room.
Report 27284 for hip arthrodesis without the subtrochanteric osteotomy that distinguishes 27286. The operative report should establish the hip joint fused, laterality, and the procedure performed. The code has a 90-day global period, including the day-before preoperative visit and related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures at 50%. Modifier 50 pays bilateral procedures at 150%. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

27284 billing questions
How do I choose between 27284 and 27286?
Use 27284 for hip arthrodesis without a subtrochanteric osteotomy. When the surgeon performs that osteotomy with the fusion, consider 27286.
Does 27284 describe a hip replacement?
No. It represents fusion of the hip joint, which eliminates motion; hip replacement is a different operation.
What documentation supports 27284?
The operative report should identify the hip joint fused, the side, and the fusion procedure. It should also clarify whether a subtrochanteric osteotomy was performed.
How is bilateral hip arthrodesis reported?
Report the bilateral procedure with modifier 50. CMS pays bilateral procedures at 150%.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
