D043 – Hip dislocation - open reduction
OHIP Orthopaedic Surgery Code — MUSCULOSKELETAL SYSTEM SURGICAL PROCEDURES · Schedule of Benefits
Open reduction for a dislocated hip. This surgical procedure is listed under the Pelvis and Hip section of the Musculoskeletal System. This service is performed with suffix A for the surgeon. The fee for an assistant (suffix B) is calculated using 7 basic units plus time units (:). The fee for an anaesthesiologist (suffix C) is calculated using 7 basic units plus time units (:). As a surgical procedure, it is eligible for various premiums including age-based premiums for patients under 16 (:), after-hours procedure premiums (E409, E410) for non-elective cases (:), and the trauma premium (E420) if trauma criteria are met (:).
When to Use
- Use D043 when a closed reduction attempt has failed and an open surgical approach is required to achieve hip joint reduction.
- Use D043 for open reduction of a dislocated hip resulting from high-energy trauma where intra-articular debris or soft tissue interposition prevents closed reduction.
Common Pitfalls
- Do not bill D043 with D042 (closed reduction) on the same date of service, as these are mutually exclusive procedures for the same joint.
- Failure to document the Injury Severity Score (ISS) in the medical record will result in the rejection of the E420 trauma premium.
- Attempting to claim both an after-hours premium (E409/E410) and the trauma premium (E420) simultaneously is not permitted under OHIP rules.
Billing Tips
- Ensure the operative report clearly describes the open approach, as this distinguishes D043 from the closed reduction code D042.
- When billing for an assistant or anaesthesiologist, ensure the claim includes the correct unit calculation (7 basic units plus time) to avoid payment discrepancies.
