ICD-10 Code H91.8X9 – Other specified hearing loss, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H91.8X9 – Other specified hearing loss, unspecified ear
What it is
This code identifies hearing loss that is documented as “other specified” but does not fit a more specific ICD-10 category, and the affected ear is not identified. Use it when the record supports hearing loss but gives limited detail.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include reduced hearing, difficulty understanding speech, or abnormal audiology results, but the exact type and ear laterality are not specified.
When to use this code
Use this code when the clinician documents a specific hearing-loss type that is not otherwise classified and does not name the right or left ear. It may also fit cases where testing confirms hearing loss, but the note lacks enough detail for a more specific code. Check documentation before assigning it.
Do not use for
Do not use this code when the record identifies conductive, sensorineural, mixed, or other more specific hearing loss categories. Also avoid it if the ear is known and a laterality-specific code is available.
Coding tip
If the chart omits ear laterality, do not assume it; code only what is documented and query for clarification when possible.
