L398 – L398
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L398 for the laboratory requisition of a complete blood count (CBC) when ordered as a standalone diagnostic test.
- Apply this code when requesting a routine hemoglobin or hematocrit assessment for a patient during a scheduled follow-up visit.
Common Pitfalls
- Do not bill L398 in conjunction with a visit code if the laboratory test is performed on the same day by the physician's office, as the fee is intended for the requisition process.
- Avoid billing L398 for tests already included in a comprehensive panel or when the laboratory service is provided by an external facility that bills OHIP directly for the technical component.
Billing Tips
- Ensure the laboratory requisition is clearly documented in the patient chart to support the claim if audited, as L398 is frequently flagged for lack of supporting diagnostic intent.
