ICD-10 Code H20.82 – Vogt-Koyanagi Syndrome (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.82 – Vogt-Koyanagi syndrome
What it is
H20.82 identifies Vogt-Koyanagi syndrome, an inflammatory eye condition associated with uveitis. Use it when documentation names this syndrome specifically.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe ocular inflammation, often with bilateral involvement, and possible associated neurologic, auditory, or skin findings.
When to use this code
Use this code when the provider documents Vogt-Koyanagi syndrome or Vogt-Koyanagi-Harada syndrome. It may also apply when the record clearly links the patient’s uveitis to this diagnosis.
If the note only says “uveitis” or “iritis” without naming the syndrome, code the documented eye condition instead. Check documentation for laterality and episode details when reported.
Do not use for
Do not use H20.82 for unspecified uveitis, isolated iritis, or other inflammatory eye disorders that are not documented as Vogt-Koyanagi syndrome. Check documentation.
Coding tip
Code the syndrome only when the provider explicitly documents it; otherwise, select the most specific documented ocular diagnosis.
