T493 – T493
OHIP Other Code · Schedule of Benefits
When to Use
- Use T493 for the surgical excision of a malignant lesion of the skin or mucous membrane where the defect requires a complex reconstruction, such as a rotational or advancement flap.
- Select T493 instead of simple excision codes like S061 when the clinical documentation confirms the complexity of the tissue rearrangement required to close the surgical site.
Common Pitfalls
- Billing T493 in conjunction with a separate excision code for the same lesion is considered double-billing, as the excision is inclusive of the flap procedure.
- Submitting T493 without clear documentation of the flap dimensions and the specific technique used often leads to automatic rejection or manual audit review.
Billing Tips
- Ensure the operative report explicitly details the flap type and the necessity of the complex closure to justify the higher fee compared to standard excision codes.
