Intestine transplant rejection

This code signifies the body's immune system attacking a transplanted intestine, leading to organ dysfunction. It represents an acute or chronic rejection process occurring after an intestinal transplant. The rejection can manifest with various symptoms, including abdominal pain, diarrhea, and malabsorption.

Use this code when documentation clearly indicates a diagnosis of intestine transplant rejection, regardless of the specific type (e.g., acute, chronic, hyperacute). It is appropriate for patients experiencing symptoms or showing laboratory/biopsy evidence of the immune system's attack on the transplanted organ. This code should be used in conjunction with codes for any associated complications or manifestations of the rejection.

• Ensure the documentation explicitly states "rejection" of an "intestine transplant."
• Do not use this code for complications of the transplant that are not specifically rejection (e.g., infection, surgical complications).
• Always sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it is an ongoing condition impacting care.
