What This Code Means

A patient who has had a fully implantable artificial heart surgically placed to replace the function of a failing natural heart.

Coding Tips

•This is a rare code used for total artificial heart (TAH) implants; ensure documentation clearly indicates a fully implantable device
•Combine with severe heart failure codes and monitor closely for device malfunction or rejection

Clinical Significance

This code represents the presence of a completely implantable artificial heart that replaces natural cardiac function, indicating survival from end-stage heart failure with extremely high ongoing mortality risk. These patients require the most intensive cardiac monitoring and specialized care protocols.

Documentation Requirements

✓Confirmation of fully implantable artificial heart
✓Device manufacturer and model
✓Current device function and parameters
✓Power source and battery management
✓Anticoagulation protocols
✓Specialized monitoring requirements
✓Device-related complications or concerns
✓Bridge to transplant vs permanent therapy
