L171 – L171
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L171 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 or curettage.
- Select L171 instead of minor surgery codes like Z100 when the clinical focus is strictly the removal of a superficial benign growth rather than a diagnostic biopsy or complex surgical repair.
Common Pitfalls
- Billing L171 in conjunction with a consultation code (A007 or A008) on the same day is frequently rejected unless the procedure was not planned at the time of the initial consultation.
- Submitting L171 for multiple lesions on the same day often triggers a reduction or rejection; ensure you are using the appropriate multiple procedure rules or the correct diagnostic codes for each site if applicable.
Billing Tips
- If performing multiple L171 procedures on the same patient during one encounter, append the appropriate multiple procedure indicator to avoid automatic claim rejection.
