Anterior scleritis, bilateral

This code signifies inflammation of the anterior portion of the sclera, the white outer layer of the eye, affecting both eyes. It indicates a non-infectious inflammatory process that can cause pain, redness, and vision changes.

Assign this code when documentation clearly states "anterior scleritis" and specifies "bilateral" involvement. This diagnosis is typically supported by an ophthalmologist's examination findings, including slit-lamp biomicroscopy.

• Ensure the documentation explicitly states "anterior" scleritis; do not assume based on general scleritis.
• Verify bilateral involvement is documented; unilateral cases have different codes.
• Code any underlying systemic conditions (e.g., rheumatoid arthritis) that may be associated with scleritis as additional diagnoses.
