Retained depleted uranium fragments

This code identifies the presence of depleted uranium fragments that remain within a patient's body following an injury or exposure. These fragments are a specific type of foreign body, distinct from other metallic or non-metallic retained objects. The "depleted" aspect refers to uranium that has a lower concentration of the fissile isotope U-235 than natural uranium.

Use this code when documentation explicitly states the retention of depleted uranium fragments, typically after combat-related injuries, industrial accidents, or other exposures. It is appropriate for both acute and chronic presentations where the fragments are still present. This code should be assigned as a secondary diagnosis when the primary reason for the encounter is related to the presence or complications of these fragments.

• Ensure documentation specifically identifies the retained foreign body as "depleted uranium" to support this code.
• Do not use this code for general retained metallic fragments; a more specific code is required.
• Assign additional codes for any associated injuries, symptoms, or complications resulting from the retained fragments.
