ICD-10 Code H20.02 – Recurrent acute iridocyclitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.02 – Recurrent acute iridocyclitis
What it is
Recurrent acute iridocyclitis is a repeated inflammatory episode affecting the iris and ciliary body, the front part of the uvea. Use this code when documentation clearly describes recurring acute anterior uveitis.
Clinical signs
Typical findings include eye pain, redness, photophobia, tearing, and blurred vision. Clinical features vary; refer to documentation for evidence of recurrent acute inflammation of the anterior uveal tract.
When to use this code
Use H20.02 when the record states recurrent acute iridocyclitis, recurrent anterior uveitis, or repeated acute inflammatory flares of the iris/ciliary body. Apply it when the provider documents recurrence rather than a single isolated episode.
If laterality or a more specific cause is documented, code according to the chart and any applicable guideline. Check documentation when the note only says “uveitis” or “iritis” without confirming recurrence.
Do not use for
Do not use this code for chronic iridocyclitis, nonrecurrent acute iritis, or posterior uveitis. Check documentation if the diagnosis is nonspecific or if another ocular inflammatory disorder is named.
Coding tip
Look for the word “recurrent” in the assessment or problem list before assigning H20.02.
