ICD-10 Code H93.223 – Diplacusis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.223 – Diplacusis, bilateral
What it is
H93.223 identifies diplacusis affecting both ears. Diplacusis means the same sound is heard as two different pitches or with a shifted pitch perception.
Clinical signs
Patients may report distorted hearing, pitch mismatch, or sounds that seem doubled or out of tune. Clinical features vary; refer to documentation.
When to use this code
Use H93.223 when the clinician documents bilateral diplacusis as the diagnosis. It is appropriate when the record clearly states pitch distortion in both ears, with or without an underlying ear disorder. Check documentation if laterality is unclear.
Do not use for
Do not use this code for general hearing loss, tinnitus, or unspecified auditory distortion unless diplacusis is specifically documented. Do not assume bilateral involvement from vague hearing complaints.
Coding tip
Confirm that the note explicitly says diplacusis and bilateral before assigning H93.223.
