ICD-10 Code H91.93 – Unspecified hearing loss, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H91.93 – Unspecified hearing loss, bilateral
What it is
H91.93 identifies hearing loss affecting both ears when the type or cause is not specified in the record. Use it when documentation confirms bilateral hearing loss but does not define the pattern.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include difficulty hearing speech, needing repetition, or reduced response to sound in both ears.
When to use this code
Use this code when the provider documents bilateral hearing loss without naming conductive, sensorineural, or mixed loss. It also fits when the chart supports hearing loss in both ears, but the exact type is not recorded.
If laterality is bilateral and no more specific diagnosis is available, this code is appropriate. Review the note carefully before coding, and query if the record is unclear.
Do not use for
Do not use H91.93 when the hearing loss type is specified, such as conductive or sensorineural. Also avoid it if only one ear is affected or if documentation says hearing loss is absent.
Coding tip
Code the most specific hearing loss documented; if only “bilateral hearing loss” appears, H91.93 is the correct unspecified option.
