ICD-10 Code H93.243 – Temporary Auditory Threshold Shift, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.243 – Temporary auditory threshold shift, bilateral
What it is
H93.243 identifies a temporary, bilateral reduction in hearing sensitivity. Use it when documentation states the hearing threshold shift is transient and affects both ears.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record notes reduced hearing after noise exposure or another short-term trigger, with bilateral involvement and expected recovery.
When to use this code
Use this code when the provider documents a temporary auditory threshold shift in both ears, not a permanent hearing loss. It may apply after acute noise exposure, testing, or another reversible cause. Confirm that the chart clearly states bilateral involvement and temporary nature.
Do not use for
Do not use this code for permanent hearing loss, unspecified hearing impairment, or unilateral threshold shift. Check documentation if the record does not clearly describe a temporary bilateral condition.
Coding tip
Code only when the note explicitly supports both “temporary” and “bilateral”; otherwise, verify the diagnosis before assigning H93.243.
