Temporary auditory threshold shift, bilateral
ICD-10 H93.243 is a billable code used to indicate a diagnosis of temporary auditory threshold shift, bilateral.
Temporary auditory threshold shift, bilateral, refers to a reversible change in hearing sensitivity that occurs in both ears, typically following exposure to loud noise or ototoxic substances. This condition is characterized by a temporary increase in auditory thresholds, meaning that sounds must be louder than usual for the individual to hear them. Patients may experience symptoms such as muffled hearing, tinnitus, or a sensation of fullness in the ears. The shift is usually transient, resolving within hours to days after the exposure ceases. Diagnosis is often made through audiometric testing, which reveals elevated thresholds in both ears. Management primarily involves avoiding further exposure to loud noises and monitoring hearing recovery. In some cases, corticosteroids may be prescribed to reduce inflammation if there is concern for more permanent damage. Understanding the etiology and potential for recovery is crucial for patient education and follow-up care.
Detailed audiometric test results, patient history of noise exposure, and symptom description.
Patients presenting with hearing loss after exposure to loud environments, such as concerts or industrial settings.
Ensure that all relevant tests are documented to support the diagnosis of temporary auditory threshold shift.
Comprehensive audiological evaluations and reports, including pure-tone audiometry results.
Patients undergoing routine hearing assessments who report recent noise exposure.
Accurate recording of baseline hearing levels is essential for comparison.
Used when performing a full audiometric evaluation for a patient with suspected hearing loss.
Complete audiometric test results and patient history.
Otolaryngologists and audiologists should ensure all relevant findings are documented.
Temporary auditory threshold shifts are reversible changes in hearing sensitivity that occur after exposure to loud sounds, while permanent shifts indicate lasting damage to the auditory system, often requiring different management and coding.
