Key points before billing
Specimen to pathology
The excised specimen must be sent for histological examination.
When pathology says benign
If a lesion was excised as potentially malignant and the histology report returns benign, use the benign item (31366, or the matching special-site item).
Warts and seborrheic keratoses
Not covered — treatment attracts benefits on an attendance basis only (see TN.8.9).
Episode of care rule
Excision + closure for the same defect is one episode of care, even across attendances.
