ICD-10 Code H91.92 – Unspecified hearing loss, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H91.92 – Unspecified hearing loss, left ear
What it is
This code identifies hearing loss in the left ear when the type or cause is not documented. Use it when the record confirms unilateral left-sided hearing loss but does not specify conductive, sensorineural, or mixed loss.
Clinical signs
Patients may report reduced hearing, difficulty understanding speech, or needing higher volume on the left side. Clinical features vary; refer to documentation for exam findings, audiology results, or laterality confirmation.
When to use this code
Use H91.92 when the clinician documents left ear hearing loss without further detail. It is appropriate for initial visits, incomplete workups, or records that state “left hearing loss” only. If laterality is unclear, check documentation before coding.
Do not use for
Do not use this code if the record specifies conductive, sensorineural, or mixed hearing loss. Also avoid it when hearing loss is bilateral, generalized, or better described by another documented ear disorder.
Coding tip
Confirm that “left ear” is explicitly documented, because unspecified laterality or a more specific hearing loss type requires a different code.
