Question:
Surgery of Primary Site--Melanoma: How is Surgery of Primary Site coded when a path specimen is labeled as a “staged excision” for a cutaneous melanoma. See Discussion.
Discussion:
Patient was diagnosed on biopsy with lentigo maligna melanoma of the nasal dorsum. The only available documentation of the subsequent surgery is a single pathology report with the nasal dorsum “staged excision (debulking specimen)” and four additional “staged excision” specimens of the same site.
Is it safe to assume this is a Mohs surgery? Would it be safe to assume staged excisions of sites other than skin of face, are also Mohs surgery?
Answer:
Interpret a "staged excision" for cutaneous melanoma as a type of Mohs surgery.
Skin surgery codes are currently under review and revision. Document details in available text fields.
