Retained (nonmagnetic) (old) foreign body in lens, left eye

This code signifies the presence of a non-magnetic foreign object embedded within the lens of the left eye, which has been present for an extended period. This condition can lead to visual impairment or other ocular complications depending on the size and location of the foreign body.

Apply this code when documentation clearly indicates a retained, non-magnetic foreign body within the lens of the left eye, and the foreign body is described as "old" or long-standing. This is typically identified during an ophthalmologic examination following a history of ocular trauma or foreign body sensation.

• Differentiate between "old" (retained) and "current" foreign bodies; current foreign bodies in the lens are coded differently.
• Ensure the laterality (left eye) is explicitly documented.
• Verify the foreign body is non-magnetic; magnetic foreign bodies have distinct codes.
