R241Revision total arthroplasty hip

OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits

A surgical procedure for the revision of a total hip arthroplasty, involving the replacement of one or both of the acetabular or femoral components. This procedure is eligible for surgeon (A), assistant (B), and anaesthetist (C) billing. It may be performed with an add-on procedure for a bone graft to the acetabulum (E589) or extensive acetabular reconstruction (E593).

When to Use

  • Use R241 when performing a revision of a total hip arthroplasty that requires the replacement of either the acetabular component, the femoral component, or both.
  • Use R241 for revision surgeries involving component exchange due to aseptic loosening, infection, or periprosthetic fracture, provided the scope of work meets the definition of a revision arthroplasty.

Common Pitfalls

  • Billing R241 in conjunction with primary hip arthroplasty codes (e.g., R440) is a common error; R241 is strictly for revisions of previously placed total hip components.
  • Failing to document the specific complexity of the acetabular reconstruction when billing E593, which can lead to recovery if the 'extensive' nature of the reconstruction is not supported by the operative report.
  • Attempting to bill R241 for simple hardware removal or minor soft tissue procedures around a hip prosthesis, which should be coded under different musculoskeletal surgical codes.

Billing Tips

  • Always append E589 or E593 on the same claim as R241 if bone grafting or extensive reconstruction is performed to ensure the additional flat fee is captured.
  • Ensure the operative note explicitly details the components replaced and the extent of the acetabular reconstruction to justify the base fee and any applicable add-on codes during a potential audit.
