These complications often include graft-versus-host disease, veno-occlusive disease, or infectious complications that require specialized hematology/oncology expertise and intensive monitoring.

Documentation Requirements

• ✓History of stem cell transplant with transplant date and type
• ✓Specific complication type (GVHD, VOD, infection, graft failure)
• ✓Clinical manifestations and affected organ systems
• ✓Laboratory results and diagnostic studies
• ✓Relationship to transplant procedure and conditioning regimen
