ICD-10 Code H20.029 – Recurrent acute iridocyclitis, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.029 – Recurrent acute iridocyclitis, unspecified eye
What it is
Use this code for repeated episodes of acute iridocyclitis affecting an eye when the laterality is not documented. It indicates inflammation of the iris and ciliary body with a recurrent pattern.
Clinical signs
Clinical features vary; refer to documentation. Common findings include eye pain, redness, photophobia, and blurred vision, with exam evidence of anterior uveitis.
When to use this code
Assign H20.029 when the record clearly states recurrent acute iridocyclitis and does not identify right or left eye. Use it for coded diagnoses from ophthalmology notes, consults, or problem lists when the episode is active or being evaluated.
If documentation only says iridocyclitis, acute anterior uveitis, or uveitis without recurrence, check documentation before coding this specific code.
Do not use for
Do not use this code for chronic iridocyclitis, traumatic iritis, or other nonrecurrent anterior uveitis conditions. If the affected eye is specified, choose the laterality-specific code instead.
Coding tip
Confirm both recurrence and unspecified laterality before selecting H20.029.
