L439
L439 – L439
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L439 for the laboratory requisition of a complete blood count (CBC) when performed as a standalone service or in conjunction with an office visit.
- Bill L439 when ordering a CBC for routine monitoring of chronic conditions like anemia or during the management of suspected infections.
Common Pitfalls
- Do not bill L439 if the CBC is performed as part of a panel that is already covered under a global fee or a specific comprehensive laboratory requisition code.
- Avoid billing L439 on the same day as a general assessment code if the laboratory work is considered an integral component of the visit's diagnostic process rather than a separate requisition service.
Billing Tips
- Ensure the laboratory requisition is clearly linked to the patient's diagnosis code to avoid rejection for lack of medical necessity.
- L439 is a laboratory requisition fee; ensure it is not confused with technical fees for in-office point-of-care testing which may fall under different billing categories.
