L637 – L637
OHIP Dermatology Code · Schedule of Benefits
When to Use
- Use L637 for the excision of a malignant lesion on the trunk or extremities when the lesion diameter is less than 2 cm.
- Select L637 when performing a simple excision of a skin lesion that does not require complex reconstruction or flap closure.
- Use L637 instead of G005 or G006 when the procedure is specifically an excision of a malignant lesion rather than a diagnostic biopsy or benign removal.
Common Pitfalls
- Billing L637 in conjunction with a minor assessment code (A007) on the same day is frequently rejected unless the assessment is for an unrelated condition.
- Submitting L637 for benign lesions is a common audit trigger; ensure the pathology report confirms malignancy to support the code selection.
- Failing to include the specific site of the lesion in the claim notes often leads to manual review or rejection by the Ministry.
Billing Tips
- If the excision requires a complex closure, bill the appropriate repair code (e.g., Z301) in addition to L637, ensuring the total length of the repair is documented.
- Always verify the lesion size against the Schedule of Benefits, as lesions 2 cm or larger require the use of higher-valued codes such as L638.
