Ophthalmia nodosa, right eye

This code signifies an inflammatory condition of the right eye characterized by the presence of nodules, often resulting from foreign body reactions, particularly to insect hairs or plant material. These nodules are typically granulomatous and can affect various parts of the ocular surface or adnexa.

Apply this code when documentation explicitly states ophthalmia nodosa affecting the right eye. This diagnosis is typically supported by an ophthalmologist's examination noting characteristic nodular lesions and a history of exposure to causative foreign bodies.

• Ensure laterality is clearly documented as "right eye" to support this specific code.
• Distinguish from other forms of conjunctivitis or keratitis that do not involve nodule formation.
• Consider co-reporting with an external cause code if the foreign body exposure is known and documented.
