L636 – L636
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L636 for the laboratory requisition of a complete blood count (CBC) when ordered as a standalone diagnostic test.
- Apply this code when ordering a basic hematological profile to investigate anemia or infection in an outpatient setting.
Common Pitfalls
- Do not bill L636 in conjunction with a full physical examination code like A007, as the laboratory requisition fee is considered inclusive of the office visit.
- Avoid billing L636 if the laboratory test is performed within a hospital setting, as these are typically covered under global hospital budgets rather than physician fee-for-service.
Billing Tips
- Ensure the diagnostic code linked to L636 matches the clinical indication documented in the patient chart to avoid automated rejection for medical necessity.
