L004 – Laboratory Medicine - Technical Component (L001-L799 range)
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L004 only when billing for the technical component of a laboratory test as defined in the Schedule of Benefits for Laboratory Services.
- Apply this code when the laboratory service is performed in a licensed facility setting, distinct from office-based diagnostic procedures.
Common Pitfalls
- Billing L004 for in-office glucose testing is a common error; you must use G002 for all glucose-related diagnostic tests performed in your own office.
- Submitting L004 for services related to in-vitro fertilization or artificial insemination will result in automatic rejection as these are non-insured services.
- Confusing the L001-L799 technical range with the L800+ series, which are subject to different billing rules and fee schedules.
Billing Tips
- Ensure your billing software is configured to pull from the separate Schedule of Benefits for Laboratory Services, as these codes are excluded from the standard Physician Schedule of Benefits numeric index.
