ICD-10 Code H20.023 – Recurrent acute iridocyclitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.023 – Recurrent acute iridocyclitis, bilateral
What it is
This code identifies recurrent episodes of acute iridocyclitis affecting both eyes. It refers to inflammation of the iris and ciliary body that returns over time, with bilateral involvement documented.
Clinical signs
Typical findings include eye pain, redness, photophobia, and blurred vision. Clinical features vary; refer to documentation for evidence of recurrent acute inflammation in both eyes.
When to use this code
Use this code when the record clearly states recurrent acute iridocyclitis and specifies bilateral eye involvement. It is appropriate for outpatient, emergency, or specialist notes documenting repeat inflammatory episodes rather than a single isolated event.
If the laterality is not documented, or if the condition is described only as uveitis or iritis, check documentation before coding. You should code the most specific diagnosis supported by the provider’s note.
Do not use for
Do not use this code for unilateral iridocyclitis or for nonspecific eye inflammation without recurrence. Do not assign it when the chart does not confirm both eyes are involved.
Coding tip
Verify both recurrence and bilateral laterality in the provider’s documentation before assigning H20.023.
