L453 – L453
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L453 for the laboratory requisition of a complete blood count (CBC) when performed in a community setting.
- Apply this code when ordering a standard hemoglobin and hematocrit assessment as a standalone laboratory investigation.
Common Pitfalls
- Do not bill L453 in conjunction with a comprehensive panel code that already includes a CBC, as this will trigger a duplicate service rejection.
- Avoid billing L453 for point-of-care testing performed in-office, as this code is strictly for laboratory requisitions sent to an external facility.
Billing Tips
- Ensure the diagnostic code linked to L453 justifies the medical necessity of the blood work to prevent automated audit flags for excessive testing.
