ICD-10 Code H20.23 – Lens-induced iridocyclitis, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.23 – Lens-induced iridocyclitis, bilateral
What it is
This code identifies inflammation of the iris and ciliary body in both eyes that is caused by the lens. Use it when documentation states lens-induced iridocyclitis and specifies bilateral involvement.
Clinical signs
Typical findings include eye pain, redness, photophobia, and blurred vision. Clinical features vary; refer to documentation, especially for evidence linking the inflammation to the lens.
When to use this code
Use H20.23 when the provider documents bilateral iridocyclitis or anterior uveitis attributed to lens-related disease. It is appropriate when the record clearly states the lens is the cause, such as after cataract-related changes or other lens pathology. If laterality or cause is unclear, check documentation before coding.
Do not use for
Do not use this code for iridocyclitis without lens involvement or when only one eye is affected. Do not assume it for unspecified anterior uveitis or other ocular inflammation.
Coding tip
Confirm both the lens cause and bilateral laterality in the provider note before assigning H20.23.
