Unsp retained (old) intraocular fb, nonmagnetic, bilateral

This code describes the presence of an old, nonmagnetic foreign object within both eyes, where the specific type or location of the foreign body is not documented. This condition can lead to chronic inflammation, vision impairment, or other ocular complications. "Retained" implies the foreign body has been present for some time, not an acute injury.

Use this code when documentation indicates a long-standing, nonmagnetic foreign body in both eyes, but the specific nature (e.g., glass, plastic) or precise intraocular location (e.g., anterior chamber, vitreous) is not specified. This code is appropriate when the foreign body is discovered incidentally or during evaluation for chronic ocular symptoms, and further detail is unavailable.

• Ensure documentation explicitly states "bilateral" involvement; otherwise, use a unilateral code.
• Only use this "unspecified" code when no further detail about the foreign body's type or specific intraocular location is provided in the medical record.
• Sequence this code after any acute injury code if the retained foreign body is a sequela of a previous trauma.
