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.

27132 billing questions
How does this differ from a primary total hip replacement?
Use this code when the total replacement converts a hip previously treated surgically. A primary replacement in a previously unoperated joint is reported with 27130.
Can this be reported when converting a partial hip replacement?
Yes, conversion of a prior partial replacement to a total replacement is a typical conversion scenario. Document the prior implant and the conversion performed.
When is 27134 more appropriate?
Use 27134 for revision of an existing total hip replacement involving both components. This code describes conversion of prior hip surgery to a total replacement, not revision of an existing total hip replacement.
How should bilateral conversions be reported?
For bilateral procedures, report modifier 50; CMS pays the bilateral procedure at 150%.
What global-period and assistant-surgeon rules apply?
The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. Assistant-at-surgery payment may be made; co-surgeon payment requires supporting documentation.
