Disorders of unspecified acoustic nerve

This code signifies a non-specific impairment or pathology affecting the eighth cranial nerve, which is responsible for transmitting auditory and balance information from the inner ear to the brain. It indicates that the precise nature or cause of the acoustic nerve dysfunction is not specified in the medical record.

This code is appropriate when documentation indicates a disorder of the acoustic nerve, but lacks further specificity regarding the type (e.g., neuritis, neuroma) or laterality. It can be used for symptoms like unexplained hearing loss, tinnitus, or vertigo when attributed to the acoustic nerve without a definitive diagnosis.

• Avoid using this code if a more specific diagnosis of the acoustic nerve disorder is documented (e.g., acoustic neuroma, vestibular neuritis).
• Always query the provider for greater specificity regarding the nature and laterality of the acoustic nerve disorder if possible.
• Consider sequencing this code with codes for associated symptoms like hearing loss (H90.-) or vertigo (R42) if the acoustic nerve disorder is not fully explained.
