L493 – L493
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L493 for the laboratory requisition of a complete blood count (CBC) when performed as a stand-alone service or in conjunction with an office visit.
- Apply this code when ordering a CBC to monitor hematological status for patients on chronic medications like methotrexate or lithium.
Common Pitfalls
- Do not bill L493 if the laboratory test is performed within a hospital setting, as the technical fee is covered by the hospital global budget.
- Avoid billing L493 alongside a comprehensive assessment if the lab work is considered a routine part of the physical examination fee.
Billing Tips
- Ensure the laboratory requisition clearly indicates the clinical indication to avoid potential rejection or audit queries regarding medical necessity.
