ICD-10 Code H93.299 – Other abnormal auditory perceptions, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.299 – Other abnormal auditory perceptions, unspecified ear
What it is
H93.299 identifies abnormal auditory perceptions affecting an unspecified ear. Use it for ear-related hearing sensations that are not otherwise classified, such as unusual sound perception when the record does not give a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Patients may report sounds that are distorted, unusual, or perceived without a clear external source, but the chart should support that the symptom is auditory and not better explained by another disorder.
When to use this code
Use this code when the provider documents an abnormal auditory perception and does not specify the ear involved. It is appropriate when the note describes an atypical hearing sensation but does not support a more detailed ear-specific code. Check documentation if the complaint is vague, transient, or part of another diagnosed condition.
Do not use for
Do not use it for common hearing loss, tinnitus, or ear pain unless the record specifically describes an abnormal auditory perception. If the condition is better documented with a more specific diagnosis, code that instead.
Coding tip
Confirm the provider’s wording and laterality before assigning H93.299; if the ear is specified, choose the more precise code.
