L657 – L657
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L657 for the excision of a malignant lesion on the trunk or limbs when the pathology report confirms a diagnosis requiring excision.
- Apply this code for the surgical removal of a lesion where the procedure involves a simple excision without the complexity of a flap or graft repair.
Common Pitfalls
- Billing L657 in conjunction with a minor assessment code like A007 is often rejected unless the assessment is for a separate, unrelated clinical issue.
- Submitting L657 for a benign lesion is a common audit trigger; ensure the diagnosis code reflects a malignant or pre-malignant condition.
Billing Tips
- If the excision requires a complex repair, bill the appropriate repair code in addition to L657, ensuring the procedure is clearly documented as a separate surgical event.
