L423 – L423
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L423 for the laboratory handling fee when you collect a specimen in your office and forward it to a laboratory for analysis.
- Apply this code when the specimen collection is the primary service provided during the encounter, rather than as an adjunct to a comprehensive physical exam.
Common Pitfalls
- Billing L423 in addition to a full assessment code (like A007) for the same patient on the same day is often flagged as unbundling if the collection was incidental to the visit.
- Submitting L423 without a corresponding laboratory requisition or documented specimen collection event will lead to automatic rejection during post-payment audits.
Billing Tips
- Ensure the laboratory requisition is clearly linked to the date of service to support the claim if the Ministry requests proof of the specimen transfer.
