In simple words: Q85.02 is a code for a rare inherited condition called Neurofibromatosis type 2.This condition causes non-cancerous tumors to grow on the nerves in the head and spine.

Q85.02 is an ICD-10-CM code that classifies Neurofibromatosis, type 2, also known as acoustic neurofibromatosis.This is a genetic disorder characterized by the development of benign tumors on cranial and spinal nerves. It is less common than Neurofibromatosis type 1.

Example 1: A 25-year-old patient presents with progressive hearing loss and tinnitus. Imaging reveals bilateral vestibular schwannomas, consistent with Neurofibromatosis type 2. Code Q85.02 is used to document the diagnosis., A 40-year-old patient with a known diagnosis of Neurofibromatosis type 2 undergoes surgical resection of a spinal nerve schwannoma. Code Q85.02 is used to document the underlying condition., A 30-year-old patient with a family history of Neurofibromatosis type 2 undergoes genetic testing, confirming the diagnosis. Code Q85.02 is used to document the diagnosis even in the absence of overt symptoms.

Detailed family history of Neurofibromatosis type 2; imaging studies (MRI, CT) demonstrating characteristic tumors; genetic testing results (if performed).

** This code is specific to Neurofibromatosis type 2 and should not be used for other types of neurofibromatosis or related conditions.Always ensure accurate and comprehensive documentation to support the use of this code.
