ICD-10 Code H93.01 – Transient ischemic deafness (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.01 – Transient ischemic deafness
What it is
H93.01 identifies transient ischemic deafness, a temporary hearing loss thought to result from reduced blood flow to the ear or auditory pathway. Use it when documentation specifically names this condition.
Clinical signs
Typical findings include sudden, short-lived hearing loss, often with recovery. Clinical features vary; refer to documentation for laterality, associated tinnitus, vertigo, or other neurologic findings.
When to use this code
Use this code when the provider documents transient ischemic deafness as the diagnosis. It may appear in evaluations of abrupt hearing change where ischemia is considered the cause. If the record only says hearing loss or tinnitus, check documentation before assigning H93.01.
Do not use for
Do not use it for chronic hearing loss, conductive hearing loss, or unspecified auditory symptoms without a documented ischemic cause. Check documentation if the note instead describes sudden sensorineural hearing loss or another ear disorder.
Coding tip
Code H93.01 only when the clinician explicitly links the hearing loss to transient ischemia.
