Foreign body in conjunctival sac

This code describes the presence of any foreign material, such as dust, sand, or an eyelash, lodged within the conjunctival sac of the eye. It represents an acute, often irritating, ocular condition that typically causes discomfort and requires removal.

Use this code when documentation clearly indicates a foreign body is present in the conjunctiva. This diagnosis is appropriate for patients presenting with symptoms like irritation, tearing, or a foreign body sensation, and where examination confirms the foreign material's location.

• Ensure documentation specifies "conjunctival sac" to differentiate from foreign bodies in other ocular structures.
• Do not use this code if the foreign body has penetrated the globe or is embedded in the cornea.
• Consider an external cause code (E-code) to describe the circumstances of the injury, if known.
