L646 – L646
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L646 for the excision of a single benign lesion, such as a skin tag or small seborrheic keratosis, when the procedure is performed via simple excision.
- Select L646 when the lesion does not require complex closure or pathology submission, distinguishing it from more intensive minor surgery codes like Z001 or Z002.
Common Pitfalls
- Billing L646 in conjunction with a consultation or assessment code (A007/A001) on the same day is frequently rejected unless a separate, unrelated clinical issue is documented.
- Attempting to bill L646 for multiple lesions on the same site often leads to audit flags; ensure you are not exceeding the maximum allowable units for a single encounter.
Billing Tips
- If the lesion requires a formal biopsy with pathology submission, consider whether a diagnostic code like Z001 provides better compensation for the clinical work involved.
