ICD-10 Code H20.20 – Lens-induced iridocyclitis, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.20 – Lens-induced iridocyclitis, unspecified eye
What it is
H20.20 identifies iridocyclitis caused by lens-related inflammation in an unspecified eye. Use it when the record shows lens-induced anterior uveitis but does not specify right or left eye.
Clinical signs
Typical findings include eye pain, redness, photophobia, and blurred vision. Clinical features vary; refer to documentation for evidence of anterior chamber inflammation linked to the lens.
When to use this code
Use this code when the clinician documents lens-induced iridocyclitis and laterality is not stated. It also fits cases where the note clearly identifies a lens-related cause, such as retained lens material or lens changes, but the eye is unspecified.
Do not use for
Do not use H20.20 for iritis or uveitis without a lens-related cause. If the record specifies the right or left eye, check documentation for the more specific laterality code.
Coding tip
Confirm both the lens-induced cause and the unspecified eye before assigning H20.20.
