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

This diagnosis code indicates the presence of a magnetic foreign body, which has been present for an extended period (retained/old), located in the posterior wall of the left eyeball. This condition can lead to chronic inflammation, vision impairment, or other ocular complications.

Use this code when documentation specifies a magnetic foreign object embedded in the posterior globe of the left eye, and the foreign body is not acutely acquired but rather has been present for some time. This typically applies to cases where surgical removal is being considered or chronic management is required.

• Differentiate between acute foreign bodies (T15.xx) and retained/old foreign bodies.
• Ensure laterality (left eye) is clearly documented.
• Confirm the foreign body's magnetic nature and specific location within the posterior wall of the globe.
