R333 is a reconstructive surgical procedure for femoral shortening, often performed to address leg length inequality. This procedure includes the services of a surgeon (suffix A), and is eligible for an assistant (suffix B) with 6 basic units and an anaesthetist (suffix C) with 6 basic units. Time units for the assistant and anaesthetist are calculated separately based on the duration of the service.

When to Use

Use R333 for surgical femoral shortening procedures performed to correct significant leg length discrepancies.
Select R333 when the procedure is a primary shortening osteotomy, distinguishing it from lengthening procedures like R340 or R341.

Common Pitfalls

Billing R333 alongside other major musculoskeletal procedures without applying the multiple procedure rule, which requires the assistant and anaesthetist to claim units based only on the major procedure.
Failing to document the Injury Severity Score (ISS) when attempting to claim the E420 trauma premium, which leads to automatic rejection.
Incorrectly applying after-hours premiums (E409/E410) to elective cases; these are strictly reserved for non-elective procedures or elective cases delayed by emergencies.

Billing Tips

Ensure the age-based premium is applied to both the surgeon (R333A) and the assistant (R333B) when operating on patients under 16 years of age.
When performing bilateral procedures, remember that assistant and anaesthetist basic units are restricted to the primary procedure code only.
