Retained (old) foreign body in vitreous body, unsp eye

This code signifies the presence of a non-magnetic foreign object, such as a piece of glass, wood, or plastic, that has become lodged within the vitreous humor of the eye. This foreign body is considered "old" or retained, meaning it has been present for some time and is not an acute injury. The specific eye affected is not documented.

Use this code when documentation clearly indicates a retained, non-magnetic foreign body within the vitreous of an eye, and the laterality (left, right, or bilateral) is not specified. This typically occurs after a penetrating eye injury where the object was not immediately removed. Support for this code includes imaging reports (e.g., ultrasound, CT scan) confirming the foreign body and its non-magnetic nature, along with clinical notes describing its chronic presence.

• Ensure the foreign body is explicitly documented as "non-magnetic" and "retained" or "old."
• Avoid using this code if the foreign body is magnetic or if the laterality is known; instead, select a more specific code.
• Sequence this code after any codes for the initial injury that led to the foreign body, if applicable.
