ICD-10 Code H91.91 – Unspecified hearing loss, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H91.91 – Unspecified hearing loss, right ear
What it is
H91.91 identifies hearing loss affecting the right ear when the type, cause, or degree is not documented. Use it when the record confirms right-sided hearing loss but does not specify a more exact diagnosis.
Clinical signs
Typical findings include reduced hearing on the right side, difficulty understanding speech, or abnormal hearing screening results. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents hearing loss in the right ear without stating whether it is conductive, sensorineural, or mixed. It also applies when the chart lacks enough detail to assign a more specific code. Check documentation if laterality or type is unclear.
Do not use for
Do not use H91.91 if the record identifies a specific type of hearing loss or a different ear. Do not use it for normal hearing, transient ear symptoms, or suspected hearing loss without confirmation.
Coding tip
Assign the most specific hearing loss code available; if the documentation only supports right ear and unspecified type, H91.91 is appropriate.
