ICD-10 Code H91.03 – Ototoxic hearing loss, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H91.03 – Ototoxic hearing loss, bilateral
What it is
H91.03 identifies hearing loss in both ears caused by exposure to ototoxic substances, such as certain medications or chemicals. Use it when documentation clearly links the bilateral hearing loss to an ototoxic cause.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include bilateral decreased hearing, often with a history of exposure to a known ototoxic agent and audiologic evidence supporting sensorineural loss.
When to use this code
Use H91.03 when the provider documents bilateral ototoxic hearing loss or clearly attributes the hearing loss to an ototoxic exposure. You may also use it when the record states medication-induced or chemically induced hearing loss affecting both ears, if documented as ototoxic.
Do not use for
Do not use this code for unspecified hearing loss, unilateral ototoxic hearing loss, or hearing loss without a documented ototoxic cause. Check documentation if the cause is unclear.
Coding tip
Confirm both laterality and the ototoxic cause in the chart before assigning H91.03.
