Chronic follicular conjunctivitis, right eye

This code signifies a persistent inflammation of the conjunctiva characterized by the presence of follicles, specifically affecting the right eye. Follicular conjunctivitis involves lymphoid hyperplasia within the conjunctival stroma, often presenting as small, elevated lesions.

Apply this code when documentation clearly indicates a chronic presentation of follicular conjunctivitis in the patient's right eye. This diagnosis is typically supported by ophthalmological examination findings noting persistent follicles, redness, and irritation in the specified eye over an extended period.

• Ensure the documentation specifies "chronic" and clearly identifies the "right eye" to support this laterality and acuity.
• Differentiate from acute follicular conjunctivitis (H10.02-) and other forms of conjunctivitis.
• Consider co-reporting codes for underlying causes if identified, such as viral infections (e.g., adenovirus) or chlamydial infections.
