Retained (old) foreign body in ant chamber, unsp eye

This code signifies the presence of a non-magnetic foreign object, which has been in the eye for some time, located within the anterior chamber of an unspecified eye. This foreign body is not recent and does not respond to magnetic removal techniques.

Apply this code when documentation indicates a chronic, non-magnetic foreign body lodged in the anterior chamber, and the specific eye affected (right or left) is not specified. Supporting documentation would include physician notes detailing the foreign body's nature (non-magnetic, old/retained) and its location within the anterior chamber, without laterality.

• Ensure the documentation explicitly states the foreign body is "retained" or "old" and "nonmagnetic."
• Do not use this code if the foreign body is recent or if its magnetic properties are unknown.
• If laterality (right or left eye) is documented, a more specific code from the H44.71 series should be used.
