Nodular episcleritis, unspecified eye

This code signifies an inflammatory condition affecting the episclera, the thin layer of tissue between the conjunctiva and the sclera, characterized by the presence of localized nodules. It represents a non-infectious, often recurrent, inflammation that typically presents with redness and tenderness in a specific area of the eye.

Use this code when documentation indicates a diagnosis of nodular episcleritis without specifying laterality (right or left eye). This diagnosis is typically made based on clinical examination, noting a raised, reddish, and sometimes tender nodule on the episcleral surface.

• Ensure the documentation explicitly states "nodular episcleritis" and does not specify laterality.
• Distinguish from diffuse episcleritis (H15.11-) and scleritis (H15.0-), which involve different layers or patterns of inflammation.
• If laterality is documented (e.g., right or left eye), use the more specific codes H15.121 or H15.122.
