ICD-10 Code H82.1 – Vertiginous syndromes in diseases classified elsewhere, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H82.1 – Vertiginous syndromes in diseases classified elsewhere, right ear
What it is
This code identifies vertigo or related dizziness attributed to another disease process, with the right ear specified as the affected side. Use it when the record links the symptom to an underlying condition rather than to a primary inner-ear disorder.
Clinical signs
Typical findings include spinning sensation, imbalance, nausea, or positional worsening of dizziness. Clinical features vary; refer to documentation, and confirm that the right ear is documented as the involved side.
When to use this code
Use H82.1 when the provider documents vertiginous symptoms caused by another classified disease and specifies the right ear. It is appropriate when the note clearly connects the vertigo to an underlying condition, such as a systemic or neurologic disorder. If the cause or laterality is unclear, check documentation.
Do not use for
Do not use this code for unspecified vertigo, bilateral ear involvement, or vertigo due to a primary ear disease without documentation of an external cause. Do not assign it when the record does not confirm right-sided involvement.
Coding tip
Always code the underlying disease first, then add H82.1 only when the chart explicitly supports secondary vertiginous syndrome in the right ear.
