About the H80–H83 Code Range
These inner ear conditions include bone changes, disorders of balance function, vertigo associated with diseases classified elsewhere, and other inner ear problems. Otosclerosis is spongy bone formation in the inner ear’s bony capsule that can lead to hearing loss.
H80 separates otosclerosis involving the oval window from cochlear otosclerosis. Its oval window subdivisions distinguish obliterative from nonobliterative involvement. H81 separates disorders of vestibular, or balance, function by type, including Ménière’s disease, vestibular neuronitis, and peripheral or central vertigo.
H82 identifies vertigo syndromes associated with diseases classified elsewhere and separates them by right, left, both, or unspecified ear. H83 includes labyrinthitis, labyrinthine fistula or dysfunction, and noise effects on the inner ear.
