Anterior scleritis, unspecified eye

This code signifies inflammation of the anterior portion of the sclera, the white outer layer of the eye, without further specification of the affected eye. Anterior scleritis typically presents with localized pain, redness, and tenderness, and can be associated with systemic autoimmune diseases.

Use this code when documentation confirms anterior scleritis but does not specify laterality (right, left, or bilateral). This diagnosis is often supported by ophthalmological examination findings such as scleral injection, edema, and tenderness to palpation.

• Avoid using this code if laterality is documented; instead, select the more specific code for right (H15.011), left (H15.012), or bilateral (H15.013) anterior scleritis.
• Always review the medical record for any underlying systemic conditions (e.g., rheumatoid arthritis, lupus) that may be linked to the scleritis, as these should be coded as secondary diagnoses.
• Differentiate from episcleritis (H15.1-), which involves inflammation of the superficial layer of the sclera and typically has less severe symptoms.
