ICD-10 Code H20.22 – Lens-induced iridocyclitis, left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.22 – Lens-induced iridocyclitis, left eye
What it is
This code identifies inflammation of the iris and ciliary body in the left eye caused by lens-related disease. Use it when the chart specifies a lens-induced cause rather than another type of uveitis.
Clinical signs
Findings may include eye pain, redness, photophobia, tearing, and blurred vision. Clinical features vary; refer to documentation, and confirm that the inflammation is linked to the lens and limited to the left eye.
When to use this code
Use H20.22 when the provider documents lens-induced iridocyclitis affecting the left eye. It is appropriate for encounters where the diagnosis is established or being managed and the laterality is clearly stated. Check documentation if the note only says iritis or uveitis without lens involvement.
Do not use for
Do not use this code for iridocyclitis of another cause, unspecified uveitis, or right-eye disease. If the record does not confirm lens-induced origin, check documentation.
Coding tip
Verify both the lens-induced cause and left-eye laterality before assigning H20.22.
