ICD-10 Code H20.043 – Secondary noninfectious iridocyclitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.043 – Secondary noninfectious iridocyclitis, bilateral
What it is
H20.043 identifies inflammation of the iris and ciliary body in both eyes when the cause is secondary and not infectious. Use it when documentation specifies bilateral secondary noninfectious iridocyclitis.
Clinical signs
Typical findings include eye pain, redness, photophobia, and blurred vision. Clinical features vary; refer to documentation for bilateral involvement and the noninfectious secondary cause.
When to use this code
Use this code when the record states secondary iridocyclitis affecting both eyes and clearly excludes infection. It may appear with a documented underlying ocular or systemic condition that is driving the inflammation. If laterality or cause is not stated, check documentation.
Do not use for
Do not use it for infectious uveitis or unspecified iridocyclitis. Also avoid it when the chart does not confirm bilateral disease or does not identify the condition as secondary.
Coding tip
Verify both laterality and the noninfectious secondary cause before assigning H20.043.
