ICD-10 Code H93.019 – Transient ischemic deafness, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.019 – Transient ischemic deafness, unspecified ear
What it is
H93.019 identifies a temporary loss of hearing thought to be caused by reduced blood flow, affecting an ear that is not otherwise specified. Use it when the record documents transient ischemic deafness but does not name the right or left ear.
Clinical signs
Clinical features vary; refer to documentation. Records may note sudden, temporary hearing loss, reduced auditory perception, or an ischemic cause affecting the ear, with no permanent deficit described.
When to use this code
Use this code when the provider documents transient ischemic deafness and specifies neither ear. It also fits when the note confirms a temporary ischemic hearing event but does not provide enough detail for a more specific ear code. If the documentation is unclear, check documentation before assigning.
Do not use for
Do not use this code for permanent hearing loss, nonspecific tinnitus, or hearing changes from infection, trauma, or cerumen. Do not guess laterality if the chart does not support it.
Coding tip
Assign H93.019 only when transient ischemic deafness is explicitly documented and ear laterality is absent.
