Contaminated medical or biological substances (Y64)

The ICD-10 codes in the Y64 category are used to identify complications arising from the administration of contaminated medical or biological substances. These codes help specify the method by which the contaminated substance was given to a patient, such as transfusion, injection, or other means.

The ICD-10 code Y64.0 covers contaminated substances that are transfused or infused, often linked to issues like contaminated blood transfusions. The code Y64.1 applies when the contaminated substance is injected or used for immunization, including vaccinations. For contaminants introduced through other methods, Y64.8 is used, which also includes serious events like delivery of the wrong gas in oxygen lines. When the specific method of contamination is unknown, the Y64.9 code applies and covers general cases of infectious agent transmission via medicinal products. These codes assist in accurately describing adverse events from contaminated medical materials, supporting precise medical records and follow-up care.
