ICD-10 Code H91.8X3 – Other specified hearing loss, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H91.8X3 – Other specified hearing loss, bilateral
What it is
This code identifies bilateral hearing loss that does not fit a more specific ICD-10 category. Use it when the record clearly documents an other specified type affecting both ears.
Clinical signs
Patients may report reduced hearing in both ears, trouble understanding speech, or needing higher volume. Clinical features vary; refer to documentation.
When to use this code
Use H91.8X3 when the clinician documents bilateral hearing loss and specifies a type that is not otherwise classified. It also fits when the note supports “other specified hearing loss” with both ears involved. Check documentation if the exact subtype is unclear.
Do not use for
Do not use this code for unilateral hearing loss or for hearing loss with a more specific ICD-10 diagnosis. Do not assign it when the chart only says “hearing loss” without bilateral specification.
Coding tip
Code the most specific documented hearing-loss type first, and use H91.8X3 only when the record explicitly supports “other specified” and bilateral involvement.
