L684 – L684
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L684 specifically for the laboratory requisition of a complete blood count (CBC) when performed in a community setting.
- Apply this code when billing for the technical component of a routine hematology profile that does not require additional manual differentials.
Common Pitfalls
- Do not bill L684 in conjunction with more comprehensive hematology codes like L685 if the specific test parameters are already covered by the higher-value code.
- Avoid billing this code for point-of-care testing performed in-office, as L684 is strictly intended for laboratory-processed specimens.
Billing Tips
- Ensure the laboratory requisition is clearly linked to the diagnostic code that justifies the CBC to prevent automated rejection for lack of medical necessity.
