ICD-10 Code H20.11 – Chronic iridocyclitis, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.11 – Chronic iridocyclitis, right eye
What it is
H20.11 identifies chronic inflammation of the iris and ciliary body in the right eye. Use it when the record clearly states a persistent or recurrent iridocyclitis affecting only the right eye.
Clinical signs
Typical findings may include eye pain, redness, photophobia, and blurred vision. Clinical features vary; refer to documentation for laterality, chronicity, and whether the inflammation involves the iris and ciliary body.
When to use this code
Use this code when the provider documents chronic iridocyclitis, anterior uveitis, or similar wording for the right eye. It is appropriate when the condition is ongoing or recurrent and laterality is specified.
Check documentation if the note only says uveitis, iritis, or eye inflammation without confirming chronic iridocyclitis. You should also verify that the right eye is named, since laterality drives this code selection.
Do not use for
Do not use H20.11 for acute iridocyclitis, unspecified uveitis, or disease in the left eye or both eyes. If the record is unclear, check documentation.
Coding tip
Always confirm chronicity and laterality in the provider note before assigning H20.11.
