Y83-Y84: Surgical and other medical procedures as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure

The range of conditions from Y83-Y84, titled "Surgical and other medical procedures as the cause of abnormal reaction of the patient, or of later complication, without mention of misadventure at the time of the procedure", refer to scenarios where a patient's abnormal reaction or subsequent complications arise due to a surgical or other medical procedure performed. These complications can arise irrespective of how proficiently the procedure was carried out. The manifestations of these conditions can vary widely, from mild symptoms such as discomfort and minor infections to severe symptoms like post-operative bleeding or organ damage. The affected system depends on the type and location of the surgery. For example, a procedure on the heart may cause complications to the cardiovascular system. These conditions are not transmitted between individuals, but rather, are individual reactions to a medical or surgical procedure. The progress of the disease depends on the nature of complications and the patient's overall health status.
