0.000What This Code Means
The transplanted bone marrow is rejected by the recipient's immune system, causing the graft to fail and stop producing blood cells.
Coding Tips
- •Document the timeframe of rejection (acute vs. chronic) if available, as this may affect clinical management
- •Include seventh character for episode of care and consider additional codes for resulting cytopenias or infections
Clinical Significance
This represents bone marrow transplant rejection where the recipient's immune system attacks the transplanted cells, leading to graft failure and potential life-threatening complications. This requires immediate intervention with increased immunosuppression and possible re-transplantation, representing a critical medical emergency in transplant recipients.
