Condctv hear loss, uni, left ear, w unrestr hear cntra side

This code signifies a type of hearing impairment where sound transmission is disrupted in the left ear, while the right ear maintains normal hearing function. This disruption typically involves the outer or middle ear structures, preventing sound waves from reaching the inner ear effectively.

Apply this code when diagnostic audiometry confirms conductive hearing loss specifically in the left ear, with the contralateral (right) ear demonstrating normal hearing thresholds. Documentation should clearly specify the type and laterality of the hearing loss, often supported by audiogram results and physician's notes.

• Ensure the audiogram explicitly states "conductive" and "left ear" with normal hearing in the right ear.
• Differentiate from mixed or sensorineural hearing loss; do not use this code if the right ear also has hearing impairment.
• Consider an additional code for the underlying cause of the conductive hearing loss (e.g., otitis media, otosclerosis) if known and documented.
