ICD-10 Code H82.3 – Vertiginous syndromes in diseases classified elsewhere, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H82.3 – Vertiginous syndromes in diseases classified elsewhere, bilateral
What it is
Use this code for bilateral vertiginous syndromes when the dizziness or vertigo is due to another underlying disease. It tells you the vertigo is a secondary manifestation, not a primary ear disorder.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may describe vertigo, imbalance, or dizziness affecting both sides, with an identified underlying condition causing the symptom pattern.
When to use this code
Assign H82.3 when the provider documents bilateral vertiginous syndrome and links it to another disease classified elsewhere. Use it when the chart clearly identifies the cause and the laterality is bilateral.
If the record only says “dizziness” or does not specify the underlying disorder, check documentation before coding. Report the underlying condition separately when appropriate.
Do not use for
Do not use this code for nonspecific dizziness, isolated vertigo without an identified cause, or unilateral vestibular disorders. Check documentation if the condition is not clearly bilateral.
Coding tip
Always code the underlying disease first, then add H82.3 only when the provider documents bilateral vertiginous syndromes.
