Y65: Other misadventures during surgical and medical care

Y65.0: Mismatched blood used in transfusion

Mismatched blood used in transfusion, coded as Y65.0 in ICD-10 WHO 2016 classification, is a serious medical error that occurs when a patient receives a blood transfusion of the incorrect blood type. This error can happen due to misidentification of the patient or mislabeling of the blood products. If incompatible blood is transfused, the patient's immune system may react against it, potentially leading to severe complications. This reaction is known as a transfusion reaction, and its symptoms can include fever, chills, chest pain, back pain, nausea, or shortness of breath. The severity and speed of the reaction can vary greatly, from immediate and life-threatening, to slower and less severe. It can affect various systems in the body, including the immune system, cardiovascular system, and renal system.
