ICD-10 Code H91.8X – Other specified hearing loss (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H91.8X – Other specified hearing loss
What it is
Use this code for hearing loss that is documented but does not fit a more specific ICD-10 category. It covers other specified forms of hearing impairment in the ear or ears.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include reduced hearing sensitivity, difficulty understanding speech, or abnormal audiology results when the chart does not name a more specific type.
When to use this code
Use H91.8X when the provider clearly documents “other specified hearing loss” or describes a hearing loss type that is not indexed to a more specific code. It may apply when audiology or ENT notes identify an atypical hearing loss pattern. Code the documented laterality or specificity only if supported.
Do not use for
Do not use this code for unspecified hearing loss, conductive or sensorineural loss with a clearer diagnosis, or hearing loss that is better classified elsewhere. Check documentation.
Coding tip
Match the code to the exact wording in the record and confirm whether laterality or another more specific hearing loss code is documented.
