R630 – Hip disarticulation
OHIP Radiology Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Hip disarticulation is a major surgical amputation procedure performed at the hip joint. The fee for the surgeon (suffix A), assistant (suffix B), and anaesthetist (suffix C) includes all constituent and common elements of an insured service as defined in the Schedule of Benefits. This includes pre-operative evaluation, the surgical procedure itself, and post-operative care. Fees are calculated based on a combination of basic units and time units, and may be eligible for various premiums based on patient age, time of day, and clinical circumstances.
When to Use
- Use R630 for a formal hip disarticulation procedure where the entire lower extremity is removed at the hip joint.
- Use this code for traumatic amputations requiring formal surgical revision at the hip joint level, provided the procedure meets the definition of a disarticulation.
Common Pitfalls
- Billing R630 when the procedure is actually a high-level above-knee amputation (e.g., R631); ensure the surgical report confirms the hip joint was disarticulated.
- Attempting to bill additional surgical procedures performed during the same operative session without accounting for the multiple procedure rules, which may lead to automatic reductions in basic units.
Billing Tips
- Ensure the surgical report explicitly documents the disarticulation at the hip joint to support the claim during potential audits, as this is a high-value procedure.
- If the procedure is non-elective and requires travel, remember that the surgical assistant and anaesthetist must bill their respective special visit premiums (e.g., C988B, C998C) separately from the procedural fee.
