Other otosclerosis, left ear

This code signifies a diagnosis of otosclerosis affecting the left ear, 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 otosclerosis in the left ear, and the physician has not specified it as otospongiosis or obliterative. This code is appropriate for cases where the laterality is clearly documented as left, and the type of otosclerosis is described as "other" or unspecified.

• Ensure documentation clearly specifies "left ear" to avoid laterality errors.
• Do not use this code if the documentation specifies otospongiosis (H80.0-) or obliterative otosclerosis (H80.1-).
• Consider sequencing this code with codes for associated hearing loss (e.g., H90.0-H90.2) if documented.
