Other otosclerosis, bilateral

This code signifies a diagnosis of otosclerosis affecting both ears, where the specific type of otosclerosis is not further specified as otospongiosis or obliterative. Otosclerosis is a condition characterized by abnormal bone growth in the middle ear, leading to progressive conductive hearing loss.

Apply this code when documentation indicates bilateral otosclerosis without further specification of the type, such as when the physician notes "bilateral otosclerosis, unspecified type" or "other bilateral otosclerosis." This code is appropriate when the condition affects both ears and is not classified as otospongiosis (H80.0-) or obliterative (H80.1-).

• Differentiate from H80.0- (Otospongiosis) and H80.1- (Obliterative otosclerosis) based on physician documentation.
• Ensure laterality is clearly documented as bilateral; otherwise, consider H80.81 (right) or H80.82 (left).
• Always sequence this code as a primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
