Auditory recruitment, left ear

This code describes a hearing disorder characterized by an abnormal growth in the perception of loudness, specifically in the left ear. Individuals with auditory recruitment experience a disproportionately rapid increase in perceived loudness as sound intensity increases, often leading to discomfort or pain at levels that are only moderately loud for others. It is frequently associated with sensorineural hearing loss.

This code is appropriate when documentation clearly indicates auditory recruitment affecting the left ear, typically identified through audiometric testing. It is often used in conjunction with codes for the underlying sensorineural hearing loss. Supporting documentation should include audiogram results and physician notes detailing the presence and laterality of recruitment.

• Ensure the documentation specifies "left ear" for accurate laterality coding.
• Do not confuse with hyperacusis, which is an increased sensitivity to normal environmental sounds, though both can co-occur.
• Always code the underlying cause of the sensorineural hearing loss, if known, in addition to this code.
