Acustc neuritis in infec/parastc diseases classd elswhr, bi

This code signifies inflammation of the auditory nerve (cranial nerve VIII) affecting both ears, specifically when this neuritis is a manifestation or complication of an underlying infectious or parasitic disease. It indicates that the primary infection or parasitic infestation is classified elsewhere in the ICD-10-CM system.

Apply this code when documentation clearly links bilateral acoustic neuritis to an infectious or parasitic etiology, such as syphilis, Lyme disease, or mumps, and the primary infection is coded separately. Ensure the physician explicitly states the bilateral involvement and the causal relationship to the infectious/parasitic condition.

• Always sequence the underlying infectious or parasitic disease code first, followed by this code.
• Distinguish from idiopathic acoustic neuritis or neuritis due to other causes (e.g., toxic, traumatic).
• Verify documentation specifies "bilateral" involvement; otherwise, consider codes for unilateral involvement.
