Snsrnrl hear loss, uni, l ear, with rstrcd hear cntra side

This code signifies a type of hearing loss originating from damage to the inner ear or auditory nerve, specifically affecting the left ear. Crucially, it also indicates that the right ear, while not the primary site of sensorineural loss, also experiences some degree of hearing impairment.

Apply this code when documentation clearly states unilateral sensorineural hearing loss in the left ear, and also notes restricted or impaired hearing in the right (contralateral) ear. This is typically diagnosed through audiometry and otologic examination.

• Ensure documentation specifies "sensorineural" and not conductive or mixed hearing loss.
• Verify laterality for both the primary loss (left ear) and the restricted hearing (right ear).
• Do not use if the contralateral ear has normal hearing or if the hearing loss in the contralateral ear is also sensorineural and of a different severity.
