ICD-10 Code H93.221 – Diplacusis, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.221 – Diplacusis, right ear
What it is
H93.221 identifies diplacusis affecting the right ear. Diplacusis means a person hears the same sound as two different pitches or tones, which can make listening uncomfortable or confusing.
Clinical signs
Patients may report doubled or mismatched pitch perception, especially with music or speech. Clinical features vary; refer to documentation, and confirm the right ear is specifically documented.
When to use this code
Use H93.221 when the provider documents diplacusis limited to the right ear. It is appropriate when the chart clearly identifies the symptom or hearing complaint without a more specific underlying diagnosis.
If the note describes bilateral symptoms, another ear site, or a different hearing disorder, code the documented condition instead. Check documentation when the laterality is unclear.
Do not use for
Do not use this code for general hearing loss, tinnitus, or unspecified auditory distortion unless diplacusis is explicitly documented. Do not assume right-ear involvement without provider confirmation.
Coding tip
Look for exact laterality wording in the assessment or impression, because H93.221 is specific to the right ear.
