ICD10 code of Graft Versus Host Disease and ICD9 code

Graft Versus Host Disease (GVHD) is coded under ICD-10-CM as T86.09 (Other complications of bone marrow transplant) or specific sub-codes like D89.81 for Graft-versus-host disease. In the older ICD-9-CM classification system, Graft Versus Host Disease was typically documented under code 996.85.

What exactly is Graft Versus Host Disease?

Graft Versus Host Disease is a complex immune-mediated condition that occurs when donor immune cells (the graft) recognize the recipient's body (the host) as foreign and mount an attack. This typically happens following an allogeneic hematopoietic stem cell transplant. Because Graft Versus Host Disease can affect multiple organ systems—most commonly the skin, liver, and gastrointestinal tract—precise coding is essential for clinical documentation and insurance billing purposes.

How is Graft Versus Host Disease classified?

Clinicians categorize Graft Versus Host Disease based on the timing of symptom onset and clinical presentation. Understanding these distinctions is vital for treatment planning:

• Acute Graft Versus Host Disease: Historically defined as occurring within the first 100 days post-transplant, though it can occur later.


• Chronic Graft Versus Host Disease: Characterized by features similar to autoimmune or fibrotic disorders, typically appearing after 100 days.


• Overlap Syndrome: A clinical presentation where features of both acute and chronic Graft Versus Host Disease are present simultaneously.
