Ophthalmia nodosa, left eye

This code describes a granulomatous inflammation of the conjunctiva or cornea of the left eye, typically caused by foreign bodies such as insect hairs or vegetable matter. It presents as small, firm nodules and can lead to chronic inflammation and corneal damage if untreated.

Use this code when documentation specifies ophthalmia nodosa affecting the left eye. This diagnosis is often supported by a history of foreign body exposure, slit lamp examination findings of conjunctival or corneal nodules, and sometimes biopsy results.

• Ensure laterality is clearly documented as "left eye" to support this specific code.
• Distinguish from other forms of conjunctivitis or keratitis; ophthalmia nodosa is characterized by nodule formation.
• Code any underlying cause or associated foreign body separately if identified and documented.
