Z04: Examination and observation for other reasons
Z04.0: Blood-alcohol and blood-drug test
The Z04.0 code refers to situations involving blood-alcohol and blood-drug testing. It's used in scenarios where individuals undergo specific biomedical testing to determine the level of alcohol and/or drugs present in their bloodstream. The main reason for such testing is usually due to suspicion of intoxication, which can alter a person's ability to function normally and may lead to harmful behaviors or accidents. Symptoms of intoxication can vary, but often include altered coordination, slower reaction times, changes in mood or behavior, and impaired judgment or decision-making. Blood testing is a way for medical professionals to objectively measure the degree of intoxication or substance use, which can then influence further medical or legal proceedings.
