Noise effects on right inner ear

This code signifies damage to the right inner ear resulting from exposure to excessive noise. This damage can manifest as hearing loss, tinnitus, or other auditory disturbances specifically affecting the right ear's cochlea or vestibular system due to acoustic trauma.

Apply this code when documentation explicitly states noise-induced damage to the right inner ear. This typically occurs after exposure to loud sounds, such as occupational noise, recreational noise, or acute acoustic trauma. Supporting documentation should include audiometry results, patient history of noise exposure, and physician assessment confirming the right-sided inner ear involvement.

• Ensure laterality is clearly documented as "right" to support this specific code.
• Distinguish from other forms of hearing loss not related to noise exposure.
• Consider an external cause code (e.g., W49.XXXA for exposure to other man-made noise) if the source of the noise exposure is known and relevant.
