ICD-10 Code H91.10 – Presbycusis, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H91.10 – Presbycusis, unspecified ear
What it is
H91.10 identifies age-related hearing loss when the affected ear is not specified. Use it for gradual, non-congenital hearing decline associated with aging, when documentation does not identify left, right, or bilateral involvement.
Clinical signs
Typical findings include slowly progressive difficulty hearing speech, especially in noisy settings, and reduced sensitivity to higher-pitched sounds. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents presbycusis or age-related hearing loss and does not state which ear is affected. It also fits cases where the record confirms hearing loss consistent with aging but laterality is missing. Check documentation if another cause of hearing loss is documented.
Do not use for
Do not use H91.10 when the record specifies left, right, or bilateral hearing loss, or when the hearing loss has another documented cause. Do not use it for sudden, conductive, or congenital hearing loss.
Coding tip
If laterality is documented anywhere in the chart, code the more specific ear-related option instead of unspecified ear.
