ICD-10 Code H93.23 – Hyperacusis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.23 – Hyperacusis
What it is
Hyperacusis means an abnormal sensitivity to everyday sounds. You use this code when the patient reports sounds that are perceived as painfully loud or unusually intolerable.
Clinical signs
Patients may describe discomfort, pain, or startle with normal environmental noise. Clinical features vary; refer to documentation, and note whether the complaint is sound intolerance rather than hearing loss.
When to use this code
Use H93.23 when the record clearly documents hyperacusis as the diagnosis or reason for evaluation. It fits visits for sound sensitivity, auditory discomfort, or a clinician-assessed intolerance to ordinary noise. If the note only says “ear pain” or “hearing problem,” check documentation before assigning it.
Do not use for
Do not use this code for tinnitus, hearing loss, or general ear pain unless hyperacusis is specifically documented. If the chart is vague, check documentation.
Coding tip
Assign the code only when the provider names hyperacusis or clearly documents sound intolerance.
