ICD-10 Code H91.8X2 – Other specified hearing loss, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H91.8X2 – Other specified hearing loss, left ear
What it is
This code identifies hearing loss in the left ear that does not fit a more specific ICD-10 hearing-loss category. Use it when the documentation names another specified type of loss and clearly states the left ear.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include reduced hearing on the left side, difficulty understanding speech, or abnormal audiologic testing consistent with unilateral hearing loss.
When to use this code
Use H91.8X2 when the provider documents a specified left-ear hearing loss that is not sensorineural, conductive, mixed, or another defined subtype. It is appropriate when the record identifies the left ear and supports a more specific unspecified-other category. Check documentation if laterality or type is unclear.
Do not use for
Do not use this code for bilateral hearing loss, right-ear hearing loss, or hearing loss with a more specific ICD-10 diagnosis. If the chart only says “hearing loss” without further detail, check documentation.
Coding tip
Verify both laterality and the exact hearing-loss description before assigning H91.8X2.
