ICD-10 Code H93.249 – Temporary auditory threshold shift, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.249 – Temporary auditory threshold shift, unspecified ear
What it is
H93.249 identifies a temporary change in hearing sensitivity affecting an unspecified ear. Use it when the record documents a short-term auditory threshold shift but does not specify which ear is involved.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may mention reduced hearing after noise exposure or another transient cause, with later improvement or resolution.
When to use this code
Use this code when the provider documents a temporary auditory threshold shift and does not identify the ear. It may fit follow-up or evaluation notes describing transient hearing change without a more specific diagnosis. If the chart names a cause or laterality, code that documented detail instead.
Do not use for
Do not use this code for permanent hearing loss, tinnitus, or other chronic ear disorders. If the record specifies right or left ear, or a different hearing diagnosis, choose the more specific code.
Coding tip
Check the note for laterality and whether the hearing change is temporary before assigning H93.249.
