ICD-10 Code H93.233 – Hyperacusis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.233 – Hyperacusis, bilateral
What it is
H93.233 identifies hyperacusis affecting both ears. Use it when sound tolerance is abnormally reduced bilaterally and the documentation specifically states the condition is bilateral.
Clinical signs
Patients may report discomfort, pain, or distress with ordinary sounds. Clinical features vary; refer to documentation for the exact bilateral presentation and any associated ear findings.
When to use this code
Use this code when the provider documents bilateral hyperacusis, sound intolerance, or decreased tolerance to everyday noise in both ears. It may appear in ENT, audiology, or neurologic evaluations when the diagnosis is clearly stated. If laterality is not documented, check documentation.
Do not use for
Do not use it for unilateral hyperacusis or for nonspecific hearing complaints without a documented diagnosis. Do not assign it when the record only notes tinnitus, hearing loss, or noise sensitivity without confirming hyperacusis.
Coding tip
Confirm that the provider documents both laterality and hyperacusis before assigning H93.233.
