Question: Which ICD-10 code should I report for neurofibromatosis type 2? Hawaii Subscriber Answer: You should report Q85.02 (Neurofibromatosis, type 2) for neurofibromatosis type 2. Neurofibromatosis type 2 is also called NF2 or central neurofibromatosis. This type of neurofibromatosis is characterized by bilateral acoustic neuromas, tumors of the vestibulocochlear nerve (8th Cranial nerve). The main complaint you should specifically look for in the clinical records is hearing loss. Other symptoms can include tinnitus (ringing in the ears) or poor balance.
