Temporary auditory threshold shift, unspecified ear

This code signifies a transient elevation in the hearing threshold, meaning a temporary decrease in hearing sensitivity, without specifying which ear is affected. It indicates a reversible hearing impairment that is not permanent.

Apply this code when documentation clearly states a temporary auditory threshold shift but does not specify laterality (left, right, or bilateral). This is often seen after exposure to loud noise, certain medications, or barotrauma, where the hearing loss is expected to resolve.

• Only use this code when the ear affected is truly unspecified in the medical record.
• Avoid using this code if the documentation indicates permanent hearing loss; instead, select a code for sensorineural or conductive hearing loss.
• Ensure the documentation supports the "temporary" nature of the shift; otherwise, a more specific hearing loss code may be appropriate.
