Retained (old) foreign body in vitreous body, bilateral

This code signifies the presence of a non-magnetic foreign object, which has been present for an extended period (old), within the vitreous humor of both eyes. This foreign body is not composed of magnetic material and is typically a result of penetrating ocular trauma.

Apply this code when documentation clearly indicates a retained, non-magnetic foreign body in the vitreous of both eyes, often following an injury. Supporting documentation should specify the foreign body's material (non-magnetic) and its chronic presence.

• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Distinguish between magnetic and non-magnetic foreign bodies; different codes apply.
• Do not use this code for acute foreign bodies; look for codes indicating "current" or "acute" presence.
