Primary iridocyclitis, bilateral

This code signifies inflammation of both the iris and ciliary body, which are structures within the anterior segment of the eye. This condition is considered primary, meaning it is not secondary to another underlying systemic disease or ocular condition.

Apply this code when documentation explicitly states a diagnosis of iridocyclitis affecting both eyes, and the etiology is not attributed to another identifiable cause (e.g., infection, trauma, autoimmune disease). Supporting documentation should clearly indicate the bilateral involvement and the primary nature of the inflammation.

• Ensure documentation specifies "primary" and "bilateral" to accurately assign this code.
• Distinguish from secondary iridocyclitis (H20.1-) or iridocyclitis of unspecified type (H20.9-).
• Code any associated systemic conditions or infectious agents separately if identified and documented.
