Unspecified otosclerosis, unspecified ear

This code signifies a diagnosis of otosclerosis where the specific type (e.g., otic capsule, cochlear) has not been documented by the provider. It indicates an abnormal bone growth in the middle ear that can lead to progressive hearing loss, but the laterality of the affected ear is also not specified.

Use this code when the medical record clearly states a diagnosis of otosclerosis, but there is no further detail regarding the specific anatomical location or the affected ear. This code is appropriate when the physician's documentation is insufficient to assign a more specific otosclerosis code.

• Avoid using this code if the documentation specifies the type of otosclerosis (e.g., otic capsule, cochlear) or the affected ear (right, left, bilateral).
• Query the provider for clarification on the type and laterality of otosclerosis to allow for more specific code assignment.
• This code should be a last resort when no further information can be obtained, as more specific codes exist for otosclerosis.
