Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 27132 covers

This code represents conversion of a hip altered by prior surgery to a total hip replacement. The surgeon replaces the joint’s femoral and acetabular sides; the history may include a prior partial hip replacement, hip fusion, or osteotomy. Orthopedic surgeons typically perform the operation in a hospital operating room, with the conversion work addressing the changed anatomy and any existing implant or fixation material as needed.

Select this code when the operation converts prior hip surgery to a total replacement; use the primary replacement code for a joint without that conversion history and revision codes when revising an existing total hip replacement. The operative report should identify the prior procedure and describe the conversion performed. 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 payment may be made; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
