ICD-10 Code H20.041 – Secondary noninfectious iridocyclitis, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.041 – Secondary noninfectious iridocyclitis, right eye
What it is
H20.041 identifies inflammation of the iris and ciliary body in the right eye that is secondary to a noninfectious cause. Use it when the chart documents iridocyclitis linked to another noninfectious condition or trigger.
Clinical signs
Common findings include eye pain, redness, photophobia, blurred vision, and a small or irregular pupil. Clinical features vary; refer to documentation for the specific cause and laterality.
When to use this code
Use this code when the provider documents secondary noninfectious iridocyclitis affecting only the right eye. It fits cases tied to autoimmune disease, trauma, surgery, or another noninfectious condition when the record supports that relationship. If the note does not specify the cause, check documentation.
Do not use for
Do not use this code for infectious uveitis, unspecified iridocyclitis, or disease in the left eye or both eyes. Also avoid it if the record does not clearly identify the condition as secondary and noninfectious.
Coding tip
Verify both laterality and the documented underlying cause before assigning H20.041.
