T86: Failure and rejection of transplanted organs and tissues

T86.4: Liver transplant failure and rejection

Liver transplant failure and rejection (ICD-10 code T86.4) refers to a serious medical condition wherein the body's immune system recognizes the transplanted liver as foreign and initiates a response to attack it. This reaction can lead to the failure of the transplanted liver to function properly, or in severe cases, complete organ failure. Transplant rejection can occur shortly after the procedure (acute rejection) or over a long period of time (chronic rejection). It's usually revealed through symptoms such as fatigue, loss of appetite, dark urine, yellowing of the skin or eyes (jaundice), and abdominal pain. The condition is typically diagnosed through blood tests, biopsies, and tissue imaging. Without appropriate medical intervention, liver transplant rejection can lead to serious health consequences, including the need for another transplant.
