L422 – L422
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L422 for the collection of a venous blood sample via venipuncture when performed as a standalone service by a physician.
- Bill L422 when a patient returns specifically for a blood draw that was ordered during a previous consultation or visit.
Common Pitfalls
- Do not bill L422 in addition to an office visit code (e.g., A007) as the blood draw is considered bundled into the assessment fee.
- Avoid billing L422 if the blood collection is performed by nursing or lab staff, as this code is intended for physician-performed procedures.
Billing Tips
- Ensure the laboratory requisition is clearly dated and linked to the patient's chart to justify the separate encounter if audited.
