Secondary noninfectious iridocyclitis, right eye

This code signifies inflammation of the iris and ciliary body in the right eye, which is not caused by an infection but rather is a manifestation of another underlying systemic condition or localized non-infectious process. It indicates a secondary form of iridocyclitis, meaning it's a consequence of another primary disease.

Apply this code when documentation specifies non-infectious inflammation of the iris and ciliary body affecting the right eye, and the etiology is secondary to another condition (e.g., autoimmune disease, trauma, or drug-induced). Ensure the physician explicitly states "non-infectious" and identifies the right eye.

• Always code the underlying systemic condition first, if known, as this is a secondary manifestation.
• Distinguish carefully between infectious and non-infectious iridocyclitis; documentation must clearly state "non-infectious."
• Verify laterality; this code is specific to the right eye. Use the appropriate code for the left eye (H20.042) or bilateral (H20.043) if applicable.
