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

This code indicates the presence of an old, magnetic foreign body lodged within the crystalline lens of the eye, where the specific eye affected is not documented. This condition can lead to complications such as siderosis lentis, cataracts, or inflammation due to the foreign material.

Use this code when the medical record clearly states the presence of a magnetic foreign body within the lens, and the foreign body is explicitly described as "old" or "retained." This code is appropriate when the laterality (right, left, or bilateral) of the affected eye is not specified in the documentation.

• Ensure documentation specifies "magnetic" and "old" or "retained" to differentiate from acute or non-magnetic foreign bodies.
• Avoid using this code if the laterality is known; instead, select the more specific code for the right (H44.631), left (H44.632), or bilateral (H44.633) eye.
• Code any associated complications, such as cataracts (H25.-, H26.-), separately.
