ICD-10 Code H93.239 – Hyperacusis, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.239 – Hyperacusis, unspecified ear
What it is
H93.239 identifies hyperacusis affecting an unspecified ear. Use it when the record documents abnormal sensitivity to ordinary sounds but does not identify the right, left, or both ears.
Clinical signs
Patients may report that normal environmental sounds feel uncomfortably loud, painful, or intolerable. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents hyperacusis and does not specify laterality. It also fits encounters focused on evaluating sound sensitivity when the diagnosis is recorded without an ear designation. If the note says only “decreased sound tolerance” or is unclear, check documentation.
Do not use for
Do not use it for tinnitus, hearing loss, or ear pain unless hyperacusis is specifically documented. Do not assign it when a more specific ear laterality is stated.
Coding tip
Always look for laterality in the assessment, because H93.239 is the unspecified-ear option.
