ICD-10-CM Code D33.3
Benign neoplasm of cranial nerves

Billable Code
Billable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
| ICD-10 from 2011 - 2016

D33.3 is a billable ICD code used to specify a diagnosis of benign neoplasm of cranial nerves. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code D333 is used to code Vestibular schwannoma

A vestibular schwannoma is a benign primary intracranial tumor of the myelin-forming cells of the vestibulocochlear nerve (8th cranial nerve). A type of schwannoma, this tumor arises from the Schwann cells responsible for the myelin sheath that helps keep peripheral nerves insulated. Although it is commonly called an acoustic neuroma, this a misnomer for two reasons. First, the tumor usually arises from the vestibular division of the vestibulocochlear nerve, rather than the cochlear division. Second, it is derived from the schwann cells of the associated nerve, rather than the actual neurons (neuromas).
