Ophthalmia nodosa, unspecified eye

This code represents an inflammatory condition of the eye caused by foreign material, typically insect hairs or plant bristles, embedded in the conjunctiva or cornea. It presents as small, grayish-white nodules on the ocular surface, often accompanied by irritation, redness, and foreign body sensation.

Use this code when documentation confirms ophthalmia nodosa affecting an unspecified eye. This diagnosis is typically made upon slit lamp examination revealing characteristic nodules and a history of exposure to causative foreign materials. Ensure the medical record clearly indicates the absence of laterality specification.

• Only use this code when the medical record explicitly states "unspecified eye" or when laterality cannot be determined from the documentation.
• If the affected eye is specified (right or left), use the more specific codes for ophthalmia nodosa (H16.241 or H16.242).
• Consider coding any associated symptoms, such as conjunctivitis (H10.-) or foreign body sensation (H53.14-), if documented.
