ICD-10 Code H83.01 – Labyrinthitis, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.01 – Labyrinthitis, right ear
What it is
H83.01 identifies inflammation of the inner ear labyrinth on the right side. It is used when the condition is documented as affecting the right ear specifically.
Clinical signs
Typical features include vertigo, dizziness, nausea, and balance problems. Clinical features vary; refer to documentation, and confirm right-sided involvement when assigning this code.
When to use this code
Use H83.01 when the provider documents labyrinthitis and clearly states the right ear is affected. It is appropriate for confirmed diagnoses in outpatient, inpatient, or specialist notes. Check documentation if laterality is unclear or if the record only says “labyrinthitis” without side.
Do not use for
Do not use this code for nonspecific dizziness, vertigo without labyrinthitis, or left or bilateral ear involvement. Check documentation if the note describes another vestibular disorder instead.
Coding tip
Always verify laterality; the wrong ear changes the ICD-10 code.
