R624 – Amputation of tibia/fibula
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
This service covers the surgical amputation of the tibia and/or fibula. The fee for the surgeon (suffix A) is a set amount. The fees for the surgical assistant (suffix B) and anaesthesiologist (suffix C) are calculated based on basic units plus time units as defined in the Schedule of Benefits. The service includes all common and specific elements of surgical procedures, including pre-operative evaluation and routine post-operative care as outlined in the General Preamble on pages , , , and .
When to Use
- Use R624 for the definitive surgical amputation of the tibia and/or fibula, including cases of severe trauma or advanced peripheral vascular disease.
- Use this code for planned elective amputations where the procedure is localized to the lower leg, distinguishing it from more proximal procedures like knee disarticulation (R623).
Common Pitfalls
- Billing R624 alongside a separate consultation or assessment fee on the same day is a common rejection, as pre-operative evaluation is included in the surgical fee per the General Preamble.
- Failing to document the Injury Severity Score (ISS) when attempting to claim the E420 trauma premium will result in automatic audit recovery.
- Incorrectly claiming after-hours premiums (E409/E410) for elective procedures that were not delayed by an intervening surgical emergency.
Billing Tips
- Ensure that the start time of the procedure is accurately recorded to support the eligibility of after-hours or night premiums (E409, E410, E400B/C, E401B/C).
- When travel is required for non-elective R624 procedures, ensure the special visit premium (e.g., C998C, C999C) is linked to the first patient seen to avoid claim rejection.
