Noise effects on inner ear, bilateral

This code signifies damage to both inner ears resulting from exposure to excessive or prolonged noise. It encompasses conditions like bilateral noise-induced hearing loss or tinnitus directly attributable to acoustic trauma affecting both ears.

Apply this code when documentation clearly indicates that both inner ears have been adversely affected by noise exposure, leading to symptoms such as bilateral hearing loss, tinnitus, or other auditory dysfunction. Supporting documentation should include a history of noise exposure and audiological findings confirming bilateral inner ear involvement.

• Ensure the documentation explicitly states "bilateral" involvement of the inner ear due to noise.
• Do not use this code for unilateral noise effects; separate codes exist for left or right ear involvement.
• Consider sequencing this code with a more specific hearing loss code (e.g., H90.3 for bilateral sensorineural hearing loss) if documented.
