L339 – L339
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L339 as a mandatory diagnostic code to report the presence of a specific laboratory test, such as a complete blood count or electrolyte panel, when performed in the office.
- Apply L339 when billing for the technical component of a laboratory procedure that is not otherwise covered by a specific fee-for-service item.
Common Pitfalls
- Billing L339 as a standalone service without an associated professional fee code will result in an automatic rejection.
- Attempting to use L339 for tests that are already bundled into the global assessment fee, such as a basic urinalysis during a general physical, is considered double-billing.
Billing Tips
- Ensure L339 is linked to the specific diagnostic code for the condition being investigated to justify the medical necessity of the laboratory test.
