Retained (old) intraoc fb, nonmag, in oth or mult sites, bi

This code signifies the presence of a non-magnetic foreign object within the eye, which has been present for an extended period (old or retained), and is located in either multiple sites within both eyes or in a site other than the anterior chamber, iris, ciliary body, lens, vitreous body, or posterior wall of both eyes. This condition can lead to chronic inflammation, vision impairment, or other ocular complications.

Apply this code when documentation clearly indicates a long-standing, non-magnetic foreign body is present in both eyes, and its location is described as "other" or "multiple sites" within the globe. Supporting documentation should specify the non-magnetic nature of the foreign body and its bilateral presence.

• Ensure documentation specifies "retained" or "old" to differentiate from acute foreign bodies.
• Verify the foreign body is explicitly stated as "nonmagnetic" and affects "bilateral" eyes.
• Do not use for foreign bodies in specific, single intraocular sites (e.g., lens, vitreous) if a more specific code is available.
