Retained (old) fb in iris or ciliary body, unsp eye

This code signifies the presence of a non-magnetic foreign object, such as a piece of wood, plastic, or glass, embedded within the iris or ciliary body of an unspecified eye. This foreign body is considered "old" or retained, meaning it has been present for some time rather than being a recent acute injury. It indicates a chronic ocular foreign body without specifying laterality.

Apply this code when documentation confirms a non-magnetic foreign body lodged in the iris or ciliary body, and the duration of its presence suggests it is not an acute event. This is appropriate when the medical record does not specify whether the right or left eye is affected. Supporting documentation would include imaging reports (e.g., ultrasound, CT scan) or operative notes detailing the removal or observation of such a foreign body.

• Ensure the foreign body is explicitly documented as non-magnetic and located within the iris or ciliary body.
• Avoid using this code for acute foreign body injuries; instead, refer to codes in the T15 series for initial encounters.
• If laterality (right or left eye) is documented, select a more specific code from the H44.72 subcategory.
