Retained (old) foreign body in ant chamber, bilateral

This code signifies the presence of a non-magnetic foreign object, which has been retained for some time, within the anterior chamber of both eyes. This condition can lead to inflammation, glaucoma, or corneal damage if not addressed. The foreign body is typically inert and not acutely traumatic.

Apply this code when documentation specifies a non-magnetic, old, or retained foreign body located in the anterior chamber of both eyes. This is often identified during an ophthalmologic examination following a history of ocular trauma or exposure to foreign material. Documentation should clearly state the bilateral involvement and the nature of the foreign body.

• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Distinguish between magnetic and non-magnetic foreign bodies, as different codes apply.
• Do not use this code for acute foreign body sensation without a retained object, or for foreign bodies embedded in the conjunctiva or cornea.
