What This Code Means

A person who has received a heart transplant and the transplant is currently functioning.

Coding Tips

•Distinguish from heart transplant rejection or failure codes (T86.20-T86.29); use Z94.1 only for functioning transplants
•Include documentation of cardiac function status and immunosuppressive regimen

Clinical Significance

This code represents successful heart transplantation with current organ function, indicating survival from end-stage cardiac disease but requiring lifelong immunosuppressive therapy and specialized cardiac monitoring. These patients have ongoing high mortality risk and complex medication management needs.

Documentation Requirements

✓Confirmation of functioning heart transplant
✓Date of transplant if available
✓Current cardiac function and ejection fraction
✓Immunosuppressive medication regimen
✓Routine cardiac monitoring and biopsies
✓No current rejection or complications
✓Transplant cardiology follow-up
✓Original indication for transplant
