Z88: Personal history of allergy to drugs, medicaments and biological substances

Z88 in the ICD-10 refers to a group of conditions that involve a person's history of allergic reactions to drugs, medicaments, and biological substances. These conditions typically stem from the body's immune system responding excessively to certain substances in medications or biological elements such as vaccines or blood products. Common symptoms of these allergies may include hives, rash, itching, swelling, breathing difficulties, or in severe cases, anaphylactic shock. These reactions may appear after a person takes a medication or receives a specific treatment. Various systems in the body can be affected, depending on the substance causing the allergy and the severity of the reaction. Effects can range from mild discomfort at the contact site to widespread impact on the respiratory or circulatory system. The course of these conditions can vary widely, with some reactions occurring almost immediately after exposure, while others may develop over time. These types of allergies are typically identified through historical documentation of allergic reactions to specific treatments or substances.
