T86.1: Kidney transplant failure and rejection

Kidney transplant failure and rejection, as indicated by ICD-10 code T86.1, refers to a serious medical condition where the body's immune system recognizes the transplanted kidney as a foreign body and fights against it, causing the kidney to stop functioning. It can occur immediately after transplant surgery, within the first few months, or even years later. The signs and symptoms of kidney transplant failure and rejection may include pain or tenderness over the transplant site, fever, reduced urination, weight gain, and swelling in your arms or legs. In more severe cases, it may also result in a rise in creatinine levels, a condition indicating impaired kidney function. The exact reason why this rejection happens is not fully understood, but it's generally related to the body's natural defense mechanism against foreign bodies. This condition is a major hurdle in transplant medicine and needs close monitoring and specialized medical care.
