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

This code signifies the presence of an old, magnetic foreign object lodged within the eye, affecting both eyes, and located in areas other than the anterior chamber, iris, ciliary body, lens, vitreous body, or retina. "Old" indicates the foreign body has been present for an extended, unspecified period.

Use this code when documentation specifies a chronic, magnetic intraocular foreign body affecting both eyes, with its location noted as "other" or "multiple sites" within the globe. This typically follows a history of ocular trauma where the foreign body was not immediately removed.

• Ensure documentation explicitly states "magnetic" and "bilateral" involvement.
• Verify the foreign body is described as "retained" or "old" to differentiate from acute foreign bodies.
• Confirm the location is not more specifically defined (e.g., in the lens, vitreous) to avoid more specific codes.
