Retain (old) intraoc fb, magnet, in oth or mult sites, r eye

This code describes the presence of a magnetic foreign body that has been retained within the right eye for an extended period. This foreign body is located in an area other than the anterior chamber, iris, ciliary body, lens, vitreous body, or posterior wall, or it may be present in multiple intraocular sites. The "old" designation implies the foreign body has been present for some time, rather than being a recent injury.

Use this code when documentation confirms a magnetic foreign body has been retained within the right eye, and its location is specified as "other," "multiple sites," or is not precisely localized to a single, specific intraocular structure. This code is appropriate for chronic cases where the foreign body is not acutely related to a recent penetrating injury. Documentation should clearly state the magnetic nature of the foreign body and its chronic presence.

• Ensure documentation specifies the magnetic nature of the foreign body; otherwise, a non-magnetic foreign body code should be used.
• Verify the laterality (right eye) is clearly documented.
• Distinguish between "retained" (old) and "current" (acute) intraocular foreign bodies, as different code categories apply.
