2025 CPT code 27132

Conversion of previous hip surgery to total hip arthroplasty, with or without autograft or allograft.

This code applies when converting any previous hip surgery (other than a prior total hip arthroplasty) to a total hip arthroplasty. Prior surgeries can include open, percutaneous, endoscopic, or arthroscopic procedures that have resulted in a skin incision and scarring.

Modifiers may be applicable depending on the specific circumstances, such as modifier 54 (Surgical Care Only) or modifier 76 (Repeat Procedure or Service by Same Physician).

Medical necessity should be established by documenting the patient's symptoms, functional limitations, failed conservative treatment, and the rationale for performing the conversion to total hip arthroplasty.

The surgeon is responsible for performing the conversion of the previous hip surgery to a total hip arthroplasty. This includes pre-operative planning, surgical execution, post-operative care, and management of any complications.

In simple words: This procedure involves converting a previous hip surgery into a full hip replacement. The surgeon replaces the hip joint's ball and socket with artificial parts, sometimes using bone grafts.It is more difficult than a first-time hip replacement because of existing scar tissue.

This code describes a procedure where a previous hip surgery (excluding a prior total hip arthroplasty) is converted to a total hip arthroplasty. This involves replacing both the femoral and acetabular components of the hip joint with a prosthesis, and may include the use of bone grafts (autograft or allograft). The procedure is typically more complex than a primary total hip arthroplasty due to the presence of scar tissue and altered anatomy from the previous surgery.

Example 1: A patient who had an open reduction and internal fixation (ORIF) of a femoral neck fracture five years prior now requires a total hip arthroplasty due to post-traumatic arthritis. CPT code 27132 would be used., A patient with a history of hip arthroscopy for labral repair now presents with advanced osteoarthritis requiring a total hip arthroplasty. As arthroscopy involves a skin incision, 27132 is applicable. , A patient who had a previous hip surgery, other than total hip arthroplasty, now requires a total hip arthroplasty due to persistent pain and dysfunction. The surgery includes removing any existing hardware, preparing the bone, and implanting both femoral and acetabular components with allograft. CPT 27132 is reported.

Documentation should include details of the previous hip surgery, the indication for the current procedure, type of prosthesis used, use of any bone grafts, and any intraoperative complications.

** For any previous hip surgery other than total hip arthroplasty, use code 27132 for conversion to total hip arthroplasty. Do not report removal of one component and hemiarthroplasty or other revision codes separately.
