Secondary noninfectious iridocyclitis, left eye

This code represents inflammation of the iris and ciliary body in the left eye, which is not caused by an infection but is a consequence of another underlying systemic or ocular condition. This secondary inflammation can lead to symptoms such as pain, photophobia, blurred vision, and redness.

Use this code when documentation clearly indicates non-infectious iridocyclitis affecting the left eye, and the condition is secondary to another disease process. Examples include iridocyclitis associated with autoimmune disorders (e.g., rheumatoid arthritis, lupus), inflammatory bowel disease, or sarcoidosis. The medical record should specify the non-infectious etiology and laterality.

• Always code the underlying systemic or ocular condition first, followed by this code.
• Distinguish carefully between infectious (H20.01-) and non-infectious (H20.04-) iridocyclitis based on provider documentation.
• Ensure laterality (left eye) is explicitly documented to support the use of this specific code.
