L331 – L331
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L331 for the laboratory requisition of a complete blood count (CBC) when performed as a standalone diagnostic test.
- Apply this code when ordering a basic hematology profile for routine monitoring of chronic conditions like iron deficiency anemia.
Common Pitfalls
- Do not bill L331 in conjunction with a comprehensive panel code that already includes a CBC, as this constitutes unbundling.
- Avoid billing L331 when the test is performed within a hospital setting, as laboratory fees are typically covered under the hospital's global budget rather than the physician's OHIP claim.
Billing Tips
- Ensure the diagnostic code linked to L331 justifies the medical necessity of the hematology profile to prevent automated rejection during claims processing.
