ICD-10 Code H93.22 – Diplacusis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.22 – Diplacusis
What it is
Diplacusis means hearing the same sound as two different pitches or with a mismatch between the ears. Use this code for the symptom itself, not for a specific underlying ear disease.
Clinical signs
Patients may report double hearing, pitch distortion, or one ear perceiving sound differently from the other. Clinical features vary; refer to documentation.
When to use this code
Use H93.22 when the record documents diplacusis as the reason for evaluation or as a noted auditory symptom. It may appear with hearing loss, tinnitus, or other ear complaints, but the chart should clearly support the symptom. If the cause is identified, code the underlying condition as directed.
Do not use for
Do not use this code for general hearing loss, tinnitus alone, or vertigo without documented diplacusis. Check documentation if the record only describes vague hearing distortion.
Coding tip
Code the symptom only when diplacusis is explicitly documented; otherwise, verify the note before assigning H93.22.
