Anterior scleritis, left eye

This code signifies inflammation of the anterior sclera, the white outer layer of the eyeball, specifically affecting the left eye. This condition is characterized by pain, redness, and tenderness in the front part of the eye.

Assign this code when documentation clearly indicates a diagnosis of anterior scleritis localized to the left eye. Supporting documentation should include physician notes detailing symptoms, examination findings (e.g., scleral injection, tenderness), and laterality.

• Ensure laterality is explicitly documented as "left eye" to support this specific code.
• Differentiate from episcleritis (H15.1-), which involves the superficial layer of the sclera and typically presents with less severe pain.
• Look for associated systemic conditions, as scleritis can be a manifestation of autoimmune diseases, and code those conditions accordingly.
