ICD-10 Code H20.822 – Vogt-Koyanagi Syndrome, Left Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.822 – Vogt-Koyanagi syndrome, left eye
What it is
H20.822 identifies Vogt-Koyanagi syndrome affecting the left eye. Use it for this specific inflammatory eye condition when documentation names the left eye as the involved site.
Clinical signs
Clinical features vary; refer to documentation. Standard references describe ocular inflammation with findings such as uveitis, eye pain, redness, photophobia, or blurred vision.
When to use this code
Use this code when the provider documents Vogt-Koyanagi syndrome and specifies the left eye. It may also fit when the note clearly links the diagnosis to left-sided ocular involvement. If laterality is not stated, check documentation before coding.
Do not use for
Do not use this code for Vogt-Koyanagi syndrome affecting the right eye, both eyes, or unspecified eye. Do not apply it to other causes of uveitis or eye inflammation without explicit documentation.
Coding tip
Always verify laterality in the ophthalmology note; the code is eye-specific and should match the documented side.
