ICD-10 Code H91.8 – Other specified hearing loss (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H91.8 – Other specified hearing loss
What it is
H91.8 identifies a hearing loss diagnosis that is specified in the record but does not fit a more specific ICD-10 hearing loss code. Use it when the provider documents an unusual or otherwise classified hearing deficit.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include reduced hearing acuity, difficulty understanding speech, or abnormal audiology results, but the exact pattern should be supported by the provider’s note.
When to use this code
Use H91.8 when the chart clearly states “other specified hearing loss” or describes a hearing loss type that is not indexed to a more specific code. It is appropriate when the documentation names the condition but does not provide enough detail for a more exact hearing-loss category.
If the record includes laterality, cause, or a more specific hearing loss subtype, code that option instead. Check documentation when the description is vague or when the hearing loss is part of a broader ear disorder.
Do not use for
Do not use this code for unspecified hearing loss, conductive hearing loss, sensorineural hearing loss, or mixed hearing loss when a more specific code is documented. Check documentation.
Coding tip
Code H91.8 only after confirming that no more specific hearing loss code applies.
