Temporary auditory threshold shift, right ear

This code signifies a temporary elevation in the hearing threshold of the right ear, meaning the individual requires a louder sound to perceive it. This condition is typically reversible and often results from acute exposure to loud noise. It indicates a transient hearing impairment rather than a permanent loss.

Apply this code when documentation explicitly states a temporary auditory threshold shift affecting the right ear, often following noise exposure (e.g., concert, industrial noise). Supporting documentation should include audiometric findings demonstrating a temporary shift and a clear indication that the condition is not permanent.

• Differentiate from permanent hearing loss codes; this code specifically denotes a temporary shift.
• Ensure laterality is clearly documented as "right ear" to support this specific code.
• Consider an external cause code (e.g., W42.0XXA for exposure to noise) if the cause of the noise exposure is known and documented.
