Transient ischemic deafness, bilateral

This code describes a temporary loss of hearing affecting both ears due to a transient ischemic event. This condition is characterized by a sudden onset of hearing impairment that resolves completely, typically within 24 hours, without permanent damage. It is often a symptom of underlying cerebrovascular insufficiency.

Use this code for patients presenting with acute, temporary bilateral hearing loss attributed to a transient ischemic attack (TIA) affecting the auditory pathways. Documentation should clearly state the transient nature of the hearing loss and its ischemic etiology, often supported by neurological workup ruling out other causes.

• Ensure documentation specifies "bilateral" involvement; separate codes exist for unilateral transient ischemic deafness.
• Distinguish from sudden sensorineural hearing loss (SSNHL) of unknown etiology, which is coded differently.
• Always look for and code any underlying cerebrovascular conditions (e.g., atherosclerosis, carotid artery stenosis) that may be contributing to the ischemic event.
