Y64.8: Contaminated medical or biological substance administered by other means

The condition referred to by the ICD-10 code Y64.8, "Contaminated medical or biological substance administered by other means," is a specific type of healthcare-associated illness. This occurs when, during medical care, a medical or biological substance is contaminated with harmful bacteria, viruses, or other germs, and then administered to a patient through means other than injection, infusion, or transfusion. The contamination may occur due to improper handling, storage, or misuse of these substances. Presenting symptoms may vary based on the type and extent of the contamination and the patient's overall health but can range from mild discomfort to serious infections or diseases in severe cases. The consequences of such conditions can be widespread, affecting multiple body systems depending on the nature of the contaminant. These incidents are usually accidental and primarily, though not exclusively, associated with healthcare settings.
