Retained (old) fb in iris or ciliary body, left eye

This code signifies the presence of a non-magnetic, long-standing foreign object embedded within the iris or ciliary body of the patient's left eye. This is distinct from acute foreign body injuries and implies the object has been present for some time, potentially leading to chronic inflammation or other ocular complications.

Apply this code when documentation clearly indicates a retained foreign body in the iris or ciliary body of the left eye, and specifies that the object is non-magnetic and/or old. This typically arises from penetrating ocular trauma where the object was not immediately removed or was initially undetected.

• Ensure the documentation specifies "left eye" and clarifies the foreign body is non-magnetic or old/retained.
• Distinguish from acute foreign body codes (T15.02XA) or magnetic foreign bodies (H44.712).
• Always sequence this code after any underlying cause of the foreign body, if applicable, such as an injury code.
