Retained (old) fb following penetrating wound of bi orbit

This code signifies the presence of a foreign object, such as a metallic fragment or splinter, that has remained within both eye sockets (orbits) after an initial penetrating injury. The foreign body is considered "old" or retained, indicating it was not immediately removed following the initial trauma. This condition can lead to chronic inflammation, infection, or vision impairment.

Use this code when documentation clearly indicates a foreign body is still present in both orbital cavities following a past penetrating injury. This applies to cases where the foreign object was not extracted at the time of the initial trauma or was discovered incidentally later. Supporting documentation includes imaging reports (e.g., CT, MRI) confirming the foreign body's location and a history of penetrating orbital trauma.

• Differentiate from acute foreign bodies (T15.01-T15.02) which are typically removed shortly after injury.
• Ensure documentation specifies "bilateral orbits" to support this specific code; otherwise, use unilateral codes (H05.51 or H05.52).
• Always code the underlying cause of the penetrating wound (e.g., W20-W49 for struck by object, W50-W64 for other specified causes) as an external cause code.
