L433 – L433
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L433 when performing a diagnostic aspiration of a joint or bursa where the primary intent is the removal of fluid for laboratory analysis.
- Bill L433 when the procedure is performed as a standalone diagnostic service, distinct from a therapeutic injection of medication like corticosteroids.
Common Pitfalls
- Do not bill L433 in conjunction with G372 or G373 for the same joint, as the Ministry considers the aspiration an integral component of the therapeutic injection procedure.
- Avoid billing L433 when the aspiration is performed as part of a minor surgical procedure already covered under a different surgical fee code, as this constitutes unbundling.
Billing Tips
- Ensure the clinical note explicitly justifies the diagnostic necessity of the fluid analysis to support the claim during a potential audit.
