Diseases of inner ear (H80-H83)

ICD-10 codes H80-H83 cover various diseases and disorders of the inner ear, including otosclerosis, vestibular function disorders, vertiginous syndromes, and other specified or unspecified inner ear conditions. These codes help specify conditions affecting hearing and balance by detailing ear side and disease subtype.

This code range includes otosclerosis (H80 codes), a condition causing abnormal bone growth in the ear, with subcategories for nonobliterative, obliterative, cochlear, and other forms, each specifying which ear is affected. Synonyms like "nonobliterative otosclerosis" or "labyrinthitis ossificans" guide coders to appropriate codes. Disorders of vestibular function (H81 codes) capture conditions like Meniere's disease, benign paroxysmal vertigo, and vestibular neuronitis, often specifying the ear involved. For example, Meniere's disease is also called "labyrinthine hydrops" and maps to codes H81.0 through H81.09. The range also covers various types of vertigo including peripheral and central origins. H82 codes identify vertiginous syndromes linked to diseases classified elsewhere, while H83 codes include other inner ear diseases such as labyrinthitis, labyrinthine fistula, noise-induced hearing loss, and superior semicircular canal dehiscence syndrome. These detailed codes allow precise documentation of inner ear hearing and balance disorders critical for diagnosis and treatment planning.
