Disorders of acoustic nerve

This code signifies a range of pathological conditions affecting the vestibulocochlear nerve (cranial nerve VIII), which is responsible for transmitting auditory and balance information from the inner ear to the brain. These disorders can manifest as hearing loss, tinnitus, vertigo, or balance disturbances, depending on the specific portion of the nerve affected.

Apply this code when documentation indicates a primary disorder of the acoustic nerve itself, such as acoustic neuroma, vestibular neuritis, or other neuropathies impacting hearing or balance originating from the nerve. Supporting documentation should clearly identify the acoustic nerve as the site of the pathology, rather than the inner ear or central nervous system.

• Differentiate from inner ear disorders (e.g., Meniere's disease) or central nervous system conditions affecting hearing/balance pathways.
• Ensure documentation specifies "acoustic nerve" or "vestibulocochlear nerve" involvement to justify this code.
• Consider additional codes for specific manifestations like hearing loss (e.g., 389.xx) or vertigo (e.g., 780.4) if separately documented and clinically significant.
