ICD-10 Code H93.24 – Temporary auditory threshold shift (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.24 – Temporary auditory threshold shift
What it is
This code identifies a temporary decrease in hearing sensitivity after noise exposure or another short-term cause. The hearing change is expected to improve, unlike permanent hearing loss.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see muffled hearing, reduced sound perception, or a sensation of fullness in the ears after exposure to loud noise.
When to use this code
Use H93.24 when the record states a temporary auditory threshold shift, often after occupational, recreational, or accidental noise exposure. Apply it when the clinician documents a short-lived hearing change rather than established hearing loss. Check documentation if the cause or duration is unclear.
Do not use for
Do not use this code for permanent hearing loss, tinnitus alone, or unspecified ear symptoms. If the chart does not support a temporary threshold shift, check documentation.
Coding tip
Code the temporary shift only when the provider clearly documents it as a transient hearing change.
