ICD-10 Code H20.8 – Other iridocyclitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H20.8 – Other iridocyclitis
What it is
H20.8 identifies iridocyclitis, an inflammation involving the iris and ciliary body that does not fit a more specific subtype. Use it when the record says “other” iridocyclitis or gives an unspecified inflammatory pattern.
Clinical signs
Typical findings include eye pain, redness, photophobia, and blurred vision. Clinical features vary; refer to documentation for the exact laterality, cause, and severity.
When to use this code
Use H20.8 when the clinician documents iridocyclitis but does not name a more specific form such as acute, chronic, or secondary. It also fits cases where the note clearly states “other iridocyclitis” or provides enough detail to support that wording. Check documentation for laterality if your setting requires it.
Do not use for
Do not use this code for uveitis types that are documented more specifically, or for noninflammatory eye disorders. If the note does not support iridocyclitis, check documentation.
Coding tip
Match the code to the provider’s exact wording and avoid upgrading “iriditis” or “uveitis” unless the record specifically supports iridocyclitis.
