Y40-Y84: Complications of medical and surgical care
Y40-Y59: Drugs, medicaments and biological substances causing adverse effects in therapeutic use
The group of conditions classified under 'Drugs, medicaments and biological substances causing adverse effects in therapeutic use' refer to instances where individuals experience negative reactions or side-effects from medications or medical substances that are used for treatment. These substances, including drugs and medications, are intended to manage or cure a health issue. However, even when used as intended, they can sometimes lead to unexpected, harmful responses. These adverse effects can occur due to a number of reasons such as an individual's unique biological makeup, mistaken dose administration, or reactions with other substances within the body. Symptoms can vary widely based on the substance involved and the individual's reaction to it. The progression and severity of these conditions can also range from minor temporary discomfort to serious health complications. Different systems of the body could be affected, depending on the nature of the substance taken and the individual's existing health conditions.
