Chronic follicular conjunctivitis, bilateral

This code signifies a persistent inflammation of the conjunctiva characterized by the presence of lymphoid follicles, affecting both eyes. It indicates a long-standing or recurrent form of follicular conjunctivitis, distinct from acute presentations.

Apply this code when documentation specifies chronic follicular conjunctivitis affecting both the left and right eyes. Supporting documentation should include physician notes detailing the bilateral nature and chronic duration of the follicular inflammation.

• Ensure documentation explicitly states "chronic" and "bilateral" to support this specific code.
• Distinguish from acute follicular conjunctivitis (H10.2-) and other forms of chronic conjunctivitis (e.g., H10.41-, H10.42-).
• If laterality is not specified, or only one eye is affected, a different code should be selected.
