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

This code signifies the presence of a non-magnetic, typically old or long-standing, foreign object embedded within the crystalline lens of the eye. This foreign body is not readily removable with a magnet and may cause visual impairment or other complications.

Apply this code when documentation clearly indicates a foreign body lodged within the lens, specified as non-magnetic and/or old, and the affected eye is not specified. This typically occurs following penetrating ocular trauma where the foreign body has remained in situ.

• Ensure the documentation specifies "non-magnetic" or "old" to differentiate from acute or magnetic foreign bodies.
• Avoid using this code if the foreign body is located in other parts of the eye (e.g., cornea, vitreous); use more specific codes for those locations.
• Always seek clarification if the documentation does not specify laterality (right, left, or bilateral) to allow for a more precise code.
