What 27134 covers
This code describes revision surgery on both sides of a total hip prosthesis: the socket-side acetabular component and the femoral component. An orthopedic surgeon typically performs the operation in a hospital operating room when an existing replacement requires revision, such as for loosening, wear, instability, or another documented prosthesis problem. Bone graft use does not change the selection when both components are revised.
Choose this code based on the operative work, not simply the diagnosis or the fact that a prior hip replacement exists. The operative report should identify the existing prosthesis, explain the reason for revision, and document work on both components. CMS assigns a 90-day global period, including 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 services may be paid; co-surgeons require supporting documentation, and team surgery is not permitted.
