**Note 3:** Lymph nodes with isolated tumor cells (ITCs) are counted as positive lymph nodes. ITCs are defined as any tumor deposits in lymph nodes less than or equal to 0.2 mm.
**Note 4:** If there is a discrepancy between the Clark level and the pathological description of extent (invasion into the layers of the dermis), use the higher (more extensive) code.
**Note 5:** Code the greatest extent of invasion from any procedure performed on the lesion, whether it is described as a biopsy or an excision. For example, if a punch biopsy with involvement of Clark level IV is followed by a re-excision with residual tumor involving Clark level II, code 2 (Clark level IV).
**Note 6:** Satellite lesions/nodules or in-transit metastases are coded as regional nodes (code 3).
