R415 – Hip - with removal of loose body
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
An open surgical procedure on the hip joint. This procedure is variously listed in the Schedule of Benefits as: - Arthrotomy, hip - with removal of loose body - Biopsy, joint - open - Incision and Drainage, joint All these descriptions correspond to the billing code R415. The service includes the surgeon's work for the procedure. Anaesthesia and assistant services are billed separately with corresponding base units.
When to Use
- Use R415 when performing an open arthrotomy specifically to retrieve a loose body from the hip joint, as opposed to arthroscopic removal which is billed under different codes.
- Use R415 for an open joint biopsy of the hip when no other definitive procedure is performed during the same session.
- Use R415 for formal incision and drainage of the hip joint when the procedure involves an open surgical approach.
Common Pitfalls
- Do not bill R415 in conjunction with arthroscopic procedures on the same joint; the open procedure code is intended for open surgical approaches only.
- Avoid billing R415 as an 'add-on' to major hip reconstructions; if the removal of a loose body is incidental to a more comprehensive procedure like a total hip arthroplasty, it is considered part of the primary procedure and not separately billable.
- Ensure the procedure is not confused with simple aspiration or injection codes, which carry significantly lower values and different clinical requirements.
Billing Tips
- If the procedure is performed on a trauma patient meeting the specific Injury Severity Score (ISS) thresholds, apply the E420 trauma premium to increase the fee by 50%.
- When performing bilateral procedures during the same anaesthetic, ensure the major procedure is identified to correctly determine the base units for anaesthesia and surgical assistance.
