Transient ischemic deafness, right ear

This code signifies a temporary episode of hearing loss affecting the right ear, resulting from a transient reduction in blood flow to the inner ear or auditory nerve. It is characterized by a sudden onset and complete resolution of hearing impairment without permanent damage.

Use this code when documentation clearly indicates a transient ischemic event causing temporary deafness in the right ear. This diagnosis is typically supported by audiometric testing showing a temporary conductive or sensorineural hearing loss that subsequently resolves, often without a definitive cause identified beyond presumed ischemia.

• Ensure documentation specifies "transient" and "right ear" to support this specific laterality.
• Distinguish from sudden sensorineural hearing loss (SSNHL) where the hearing loss may be permanent or prolonged.
• Consider co-reporting with codes for underlying vascular conditions if identified as the cause of the ischemia.
