Secondary noninfectious iridocyclitis, bilateral

This code signifies inflammation of the iris and ciliary body in both eyes, which is not caused by an infection. It represents a secondary form of iridocyclitis, meaning it arises as a complication of another underlying systemic disease or condition rather than being a primary ocular infection.

Use this code when documentation specifies bilateral iridocyclitis that is explicitly stated as noninfectious and secondary to another condition. This often occurs in patients with autoimmune diseases, inflammatory conditions, or certain systemic syndromes affecting both eyes. The medical record should clearly indicate the noninfectious and secondary nature of the inflammation.

• Ensure documentation specifies "bilateral" involvement; otherwise, use a unilateral code.
• Always code the underlying systemic condition first, as this is a secondary diagnosis.
• Distinguish carefully from infectious iridocyclitis (H20.01x) and primary iridocyclitis (H20.02x).
