CPT® Code 0419T

Destruction of neurofibroma, extensive (cutaneous, dermal extending into subcutaneous); face, head and neck, greater than 50 neurofibromas

Destruction of neurofibromas, as indicated by CPT® Code 0419T, refers to the medical procedure aimed at removing extensive cutaneous neurofibromas, which are benign tumors that arise from peripheral nerve cells. These tumors are commonly associated with neurofibromatosis type 1 (NF-1) and type II (NF-2). Neurofibromas can manifest as multiple lesions on the skin, particularly on the face, head, and neck, and may involve more than 50 individual tumors in cases requiring this specific code. The lesions are composed of various cell types, including Schwann cells, mast cells, fibroblasts, and perineural cells, and can lead to symptoms such as pain, itching, bleeding, disfigurement, and functional interference. The procedure for destruction may utilize several techniques, including scraping, shaving, laser cautery, liquid nitrogen, electrosurgery, and desiccation. In particular, the destruction of extensive neurofibromas that extend into the subcutaneous layer is often performed using electrodesiccation, which involves applying an electrical current to dehydrate the lesion. For more superficial lesions, techniques such as fulguration and electrocoagulation may be employed. In cases where the neurofibroma presents as a protruding mass, scraping or shaving the lesion to the skin level followed by electrodesiccation may be necessary to ensure complete removal. This code is specifically designated for procedures involving the destruction of more than 50 neurofibromas located on the face, head, and neck.
