Temporary auditory threshold shift
ICD-10 H93.24 is a billable code used to indicate a diagnosis of temporary auditory threshold shift.
Temporary auditory threshold shift refers to a reversible change in hearing sensitivity, typically resulting from exposure to loud noise or other transient factors affecting the auditory system. This condition is characterized by a temporary increase in auditory thresholds, which can lead to a temporary reduction in hearing acuity. Patients may experience symptoms such as muffled hearing, tinnitus, or a sensation of fullness in the ears. The condition is often assessed using audiometric testing, which measures the hearing thresholds at various frequencies. The shift is usually temporary, resolving within a few hours to days after the exposure or removal of the causative factor. It is important to differentiate this condition from permanent hearing loss, which may arise from prolonged exposure to loud noise or other underlying pathologies. Management typically involves avoiding further exposure to loud sounds and monitoring hearing levels. In some cases, patients may benefit from counseling on hearing protection and noise exposure reduction strategies.
Detailed audiometric test results, patient history of noise exposure, and clinical findings.
Patients presenting with hearing changes after exposure to loud environments, such as concerts or industrial settings.
Ensure that the documentation clearly states the temporary nature of the auditory threshold shift and any recommendations for hearing protection.
Comprehensive audiological evaluations, including pure-tone audiometry and tympanometry results.
Patients undergoing routine hearing assessments who report recent noise exposure.
Document the specific frequencies affected and the degree of threshold shift to support the diagnosis.
Used when assessing patients with suspected temporary auditory threshold shifts.
Audiometric test results and patient history of noise exposure.
Otolaryngologists and audiologists should ensure thorough documentation of findings.
The primary cause is typically exposure to loud noise, which can temporarily affect the hair cells in the cochlea, leading to a reversible increase in hearing thresholds.
The shift usually resolves within a few hours to days after the exposure to loud noise or other causative factors.
Audiometric testing is the primary method used to diagnose this condition, measuring hearing thresholds at various frequencies.
