Presence of xenogenic heart valve

This code indicates that a patient has a heart valve replacement derived from animal tissue, such as porcine (pig) or bovine (cow) pericardium. These bioprosthetic valves are used to replace diseased or damaged native heart valves, restoring proper blood flow through the heart.

Use this code when documenting a patient's medical history or current status who has undergone a heart valve replacement using a xenograft. This applies to patients with aortic, mitral, tricuspid, or pulmonary valves replaced with animal tissue. It is a chronic condition that persists for the lifetime of the valve.

• Always assign this code as a secondary diagnosis, as it describes a historical or ongoing condition, not an acute illness.
• Do not use this code for mechanical heart valves (Z95.2) or other types of prosthetic devices.
• Ensure supporting documentation clearly specifies a xenogenic (bioprosthetic) valve replacement.
