Unspecified otosclerosis, bilateral

This code signifies an unconfirmed diagnosis of otosclerosis affecting both ears. Otosclerosis is a condition characterized by abnormal bone growth in the middle ear, leading to progressive hearing loss, typically conductive. The "unspecified" nature indicates that the specific type or stage of otosclerosis has not been determined.

This code is appropriate when the provider documents bilateral otosclerosis but does not specify the type (e.g., otospongiosis, fenestral, cochlear) or if the laterality is clearly bilateral without further detail. It should be used when the documentation lacks the specificity to assign a more precise code for otosclerosis.

• Avoid using this code if the documentation specifies a particular type of otosclerosis (e.g., fenestral, cochlear) or if the laterality is unilateral.
• Query the provider for more specific documentation regarding the type and laterality of otosclerosis if available.
• Consider sequencing this code with codes for associated symptoms like conductive hearing loss (H90.0) if documented.
