Chronic follicular conjunctivitis, unspecified eye

This diagnosis code signifies a persistent inflammation of the conjunctiva characterized by the presence of lymphoid follicles, affecting an unspecified eye. It indicates a long-standing or recurrent form of conjunctivitis where the specific eye involved is not documented.

This code is appropriate for documenting chronic follicular conjunctivitis when the medical record does not specify whether the condition affects the right or left eye, or if it is bilateral. Documentation should clearly state "chronic follicular conjunctivitis" without laterality.

• Only use this code when laterality is genuinely unspecified in the medical record; otherwise, use a more specific code.
• Distinguish from acute follicular conjunctivitis (H10.02-) which has a different clinical presentation and duration.
• Ensure the documentation supports the "chronic" nature of the condition, such as prolonged duration or recurrent episodes.
