ICD-10 Code H93.232 – Hyperacusis, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.232 – Hyperacusis, left ear
What it is
H93.232 identifies hyperacusis affecting the left ear. It means sounds are perceived as unusually loud or uncomfortable in that ear, beyond what is expected for normal hearing.
Clinical signs
Patients may report sound sensitivity, discomfort with ordinary noise, or avoidance of noisy settings. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record specifically documents hyperacusis in the left ear. It is appropriate when laterality is stated and the condition is being evaluated or recorded as a diagnosis. If the note only says hyperacusis without ear laterality, check documentation before assigning this code.
Do not use for
Do not use it for general hearing loss, tinnitus, or unspecified sound sensitivity without documented hyperacusis. If the side is not identified, do not assume left ear.
Coding tip
Confirm laterality in the provider note, because H93.232 is specific to the left ear.
