Unsp retained (old) intraocular fb, magnetic, bilateral

This code signifies the presence of an old, magnetic foreign body within both eyes, where the specific nature or location of the foreign body is not documented. An "old" foreign body implies it has been present for a significant duration, typically beyond the acute phase of injury. The magnetic property is a key characteristic, differentiating it from non-magnetic foreign bodies.

Use this code when documentation clearly indicates a retained, magnetic intraocular foreign body in both eyes, but lacks further specificity regarding its type or precise location. This code is appropriate when the foreign body is not acutely post-traumatic. Documentation should confirm the bilateral involvement and the magnetic nature of the foreign body.

• Ensure documentation specifies "magnetic" and "bilateral" involvement; otherwise, a different code for non-magnetic or unilateral foreign bodies may be more appropriate.
• If the foreign body is explicitly described as "non-magnetic," or if the laterality is unilateral, a different H44.6 subcategory code should be selected.
• Always review the medical record for any further details about the foreign body (e.g., specific type, exact location) that would allow for a more precise code selection within the H44.6 category.
