ICD-10 Code H93.222 – Diplacusis, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.222 – Diplacusis, left ear
What it is
H93.222 identifies diplacusis affecting the left ear. Diplacusis means the same sound is perceived as two different pitches or slightly different tones, usually due to an ear or auditory pathway problem.
Clinical signs
Patients may report double hearing, pitch mismatch, or distorted sound perception, especially when listening with both ears. Clinical features vary; refer to documentation.
When to use this code
Use H93.222 when the record specifically documents diplacusis in the left ear. Code it when the clinician identifies the laterality and the symptom is the reason for the visit or part of the assessed hearing complaint.
If the note only says hearing change, tinnitus, or unspecified auditory distortion, check documentation before assigning this code. Make sure the chart supports left-sided diplacusis rather than a general hearing disorder.
Do not use for
Do not use this code for unspecified diplacusis, bilateral symptoms, or unrelated hearing loss. Check documentation if the record does not clearly state the left ear.
Coding tip
Verify laterality in the provider note; H93.222 is only appropriate when left-ear diplacusis is explicitly documented.
