Retained (old) magnetic fb in ant chamber, bilateral

This code signifies the presence of an old, non-ferrous foreign object lodged in the anterior chamber of both eyes. This typically refers to a foreign body that has been present for an extended period and is not composed of magnetic material. The anterior chamber is the fluid-filled space between the cornea and the iris.

Use this code when documentation clearly indicates a long-standing, non-magnetic foreign body in the anterior chamber of both the right and left eyes. This diagnosis is often made during routine ophthalmologic examinations or when a patient presents with chronic ocular irritation or visual disturbances related to the foreign object. Supporting documentation should specify the bilateral involvement and the non-magnetic nature of the foreign body.

• Ensure documentation specifies "retained" or "old" to differentiate from acute foreign bodies.
• Verify that the foreign body is explicitly stated as "magnetic" or "non-magnetic" to select the correct subcategory. This code is for magnetic foreign bodies.
• Confirm bilateral involvement; if only one eye is affected, use the appropriate unilateral code (H44.611 or H44.612).
