L501 – L501
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L501 for the laboratory requisition of a complete blood count (CBC) when performed as a standalone service or in conjunction with an office visit.
- Apply this code when billing for the professional component of a standard hematology panel requisitioned for routine monitoring or diagnostic screening.
Common Pitfalls
- Avoid billing L501 if the laboratory service is already bundled into a comprehensive procedure code or a specific diagnostic premium that includes lab processing.
- Do not bill L501 in addition to a hospital-based laboratory fee, as this code is intended for community-based outpatient requisitions.
Billing Tips
- Ensure the laboratory requisition is clearly linked to the patient's diagnostic code to avoid rejection for lack of medical necessity.
