Corneal foreign body

This code signifies the presence of an exogenous object embedded in or adhering to the cornea of the eye. It represents a common ocular injury resulting from various environmental exposures.

Use this code when documentation clearly indicates a foreign body lodged in the cornea, often presenting with symptoms like pain, redness, tearing, and photophobia. This diagnosis is typically made after a slit lamp examination confirms the foreign body's presence and location.

• Differentiate from foreign body in the conjunctiva (930.1) or eyelid (930.2).
• Always review documentation for laterality (e.g., right eye, left eye, bilateral) if specified, though ICD-9-CM 930.0 does not allow for laterality.
• Consider an external cause code (E-code) to describe the circumstances of the injury, if known.
