ICD-10 Code H93.231 – Hyperacusis, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.231 – Hyperacusis, right ear
What it is
H93.231 identifies hyperacusis affecting the right ear. This code means sound is perceived as unusually loud or uncomfortable in that ear.
Clinical signs
Patients may report marked sensitivity to ordinary sounds, ear discomfort, or difficulty tolerating noise on the right side. Clinical features vary; refer to documentation.
When to use this code
Use H93.231 when the record specifically documents hyperacusis in the right ear. Apply it for unilateral sound intolerance when the provider identifies the right ear as the affected side. If laterality is not documented, check documentation before coding.
Do not use for
Do not use this code for general hearing loss, tinnitus alone, or unspecified hyperacusis without right-ear documentation. Check documentation if the record does not clearly state laterality.
Coding tip
Confirm the affected ear in the provider note before assigning H93.231.
