Other otosclerosis, unspecified ear

This code signifies a form of otosclerosis that does not fit into more specific categories, affecting an unspecified ear. Otosclerosis is a condition characterized by abnormal bone growth in the middle ear, leading to progressive hearing loss. This particular code is used when the specific type of otosclerosis (e.g., otospongiosis, cochlear otosclerosis) is not documented.

Apply this code when the medical record clearly states a diagnosis of otosclerosis, but the specific anatomical location (e.g., stapes, cochlea) or the ear affected (left, right, bilateral) is not specified. Documentation should indicate a diagnosis of otosclerosis without further detail.

• Avoid using this code if the specific type of otosclerosis (e.g., H80.0- for otospongiosis, H80.1- for cochlear otosclerosis) or the affected ear is documented.
• Always seek clarification from the provider if the documentation is ambiguous regarding the type or laterality of otosclerosis.
• This code is a "not otherwise specified" (NOS) code; strive for greater specificity when possible.
