Retained (old) magnetic fb in post wall of globe, right eye

This code signifies the presence of a magnetic foreign body that has been lodged in the posterior wall of the right eye for an extended period, indicating it is not a recent injury. This condition can lead to chronic inflammation, vision impairment, or other complications due to the persistent foreign material within the ocular structure.

Apply this code when documentation clearly indicates a magnetic foreign body is present in the posterior wall of the right globe and is identified as "old" or "retained." This typically occurs following a penetrating ocular injury where the foreign body was not immediately removed or was initially undetected. Supporting documentation includes imaging reports (e.g., X-ray, CT scan, MRI if non-magnetic), operative reports detailing removal of a retained foreign body, or ophthalmological examination notes confirming its chronic presence.

• Ensure documentation specifies "magnetic" and "retained" or "old" to differentiate from acute foreign bodies or non-magnetic materials.
• Verify the laterality is explicitly stated as "right eye"; avoid using unspecified laterality codes if the right eye is documented.
• Consider sequencing this code as a primary diagnosis if the retained foreign body is the reason for the encounter, or as a secondary diagnosis if it's an underlying cause of another ocular condition being treated.
