Condctv hear loss, uni, left ear with rstrcd hear cntra side

This code signifies a conductive hearing impairment affecting the left ear, where sound transmission is disrupted in the outer or middle ear. Additionally, the patient experiences some degree of hearing restriction in the right (contralateral) ear, though the primary conductive loss is unilateral to the left.

Apply this code when audiometric testing confirms conductive hearing loss exclusively in the left ear, and the patient's medical record also documents reduced hearing sensitivity in the right ear. Supporting documentation includes audiograms showing an air-bone gap in the left ear and elevated thresholds in the right ear, along with physician notes detailing the laterality and type of hearing loss.

• Ensure documentation clearly specifies "conductive" hearing loss for the left ear and mentions "restricted hearing" or similar impairment for the right ear.
• Do not use this code if the hearing loss in the right ear is also conductive; a different code for bilateral conductive loss would be more appropriate.
• Verify that the laterality is explicitly stated as unilateral left with contralateral involvement, not simply bilateral hearing loss.
