Retained (old) fb in posterior wall of globe, bilateral

This code signifies the presence of a non-magnetic foreign object embedded in the posterior wall of both eyeballs. This foreign body is considered "old," indicating it has been present for an extended period rather than being a recent injury. It describes a chronic condition affecting both eyes.

Use this code when documentation clearly indicates a non-magnetic foreign body, such as glass or plastic, is lodged in the posterior globe of both eyes. This diagnosis is typically made following imaging studies (e.g., CT scan, MRI) and a detailed history confirming the chronic nature of the foreign body.

• Ensure documentation specifies "nonmagnetic" and "old" for accurate code assignment.
• Verify laterality; this code is specifically for bilateral involvement.
• Distinguish from acute foreign bodies or those in other parts of the globe.
