Injury of acoustic nerve, unspecified side, init encntr

This code signifies damage to the eighth cranial nerve, also known as the vestibulocochlear nerve, which is responsible for hearing and balance. The injury is of an unspecified nature and laterality, indicating that the specific cause or side of involvement is not yet determined.

Apply this code for initial encounters when a patient presents with symptoms suggestive of acoustic nerve damage, such as sudden hearing loss, tinnitus, vertigo, or balance disturbances, and the precise etiology or affected side is not documented. This is appropriate when the provider has not yet specified the type of injury (e.g., contusion, laceration) or the specific ear involved.

• Do not use this code if the laterality (left or right) or the specific type of acoustic nerve injury is documented; instead, select a more specific code.
• Ensure documentation supports an "initial encounter" for the treatment of the injury.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter.
