Ototoxic hearing loss, right ear

This code signifies hearing loss in the right ear specifically caused by exposure to ototoxic substances. These substances can damage the inner ear, leading to sensorineural hearing impairment. The hearing loss is a direct consequence of the toxic agent's effect on the auditory system.

Use this code when documentation clearly indicates hearing loss in the right ear attributed to ototoxic medications (e.g., certain antibiotics, chemotherapy agents) or other chemical exposures. The medical record should specify the laterality and the causative ototoxic agent or event.

• Ensure documentation explicitly states "right ear" and identifies the ototoxic cause.
• Do not confuse with other types of sensorineural hearing loss without a specified ototoxic etiology.
• Code the specific ototoxic agent (e.g., T36-T65 for poisoning by drugs, medicaments, and biological substances) as an additional diagnosis, if known and relevant.
