Y40-Y84: Complications of medical and surgical care

The group of conditions labeled as complications of medical and surgical care refers to undesirable health outcomes that arise from health interventions. These include, but are not limited to, adverse drug interactions, infections acquired during hospital stay, accidental lacerations or punctures during procedures, anesthetic complications, and failed surgical and medical procedures. The causes can vary widely, from human error to patient-specific factors, like weakened immune systems making one more susceptible to infections. Symptoms also fluctuate based on the exact complication, such as developing a fever from an infection or experiencing unusual bleeding from a surgical site. These complications can exhibit different progressions and affect various systems in the body, depending primarily on the pre-existing medical or surgical intervention.
