ICD-10 Code H20.032 – Secondary infectious iridocyclitis, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.032 – Secondary infectious iridocyclitis, left eye
What it is
This code identifies iridocyclitis, an inflammatory condition of the iris and ciliary body, in the left eye when it is secondary to an infection. Use it when the record clearly links the inflammation to an infectious cause.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include ocular pain, redness, photophobia, tearing, and blurred vision, with slit-lamp evidence of anterior chamber inflammation.
When to use this code
Use H20.032 when the provider documents infectious iridocyclitis affecting the left eye and specifies that it is secondary to infection. The chart should support laterality and the infectious etiology. If the cause or eye is not stated, check documentation before coding.
Do not use for
Do not use this code for noninfectious uveitis or iridocyclitis without an infectious cause. Also avoid it when the affected eye is not documented as the left eye.
Coding tip
Verify both laterality and the infectious source in the provider note before assigning H20.032.
