ICD-10 Code H93.011 – Transient ischemic deafness, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.011 – Transient ischemic deafness, right ear
What it is
This code identifies a temporary loss of hearing in the right ear attributed to ischemia, meaning reduced blood flow. Use it for a documented transient vascular cause affecting hearing, not for nonspecific hearing complaints.
Clinical signs
Clinical features vary; refer to documentation. You may see sudden, short-lived hearing reduction in the right ear, sometimes with associated ear fullness or other ischemic symptoms if recorded.
When to use this code
Use H93.011 when the provider documents transient ischemic deafness limited to the right ear. It fits encounters where the diagnosis is made clinically or by specialist assessment and the record supports a temporary ischemic process. If laterality or ischemic cause is unclear, check documentation before coding.
Do not use for
Do not use this code for chronic hearing loss, conductive hearing problems, or deafness without a documented ischemic and transient nature. Check documentation if the record only states hearing loss or tinnitus.
Coding tip
Verify both laterality and the transient ischemic cause in the note before assigning H93.011.
