Y90: Evidence of alcohol involvement determined by blood alcohol level

Y90.1: Blood alcohol level of 20-39 mg/100 ml

Blood alcohol level of 20-39 mg/100 ml refers to a specific range of blood alcohol concentration (BAC) found in an individual's blood sample. Blood alcohol levels can be ascertained through laboratory testing, typically after ingestion of alcohol. By measuring BAC, it is possible to estimate the degree of intoxication a person has reached. A BAC between 20-39 mg/100 ml is generally considered very mild. At this level, an individual might experience some light alteration in mood, behavior, and coordination but serious impairment is unlikely. However, the effect of alcohol can vary greatly between individuals, based on factors such as body weight, tolerance, sex, and whether or not one has consumed food before drinking. This is classified as a type of toxic effect due to the introduction of alcohol into the body. The potential symptoms or reactions to this level of alcohol consumption are subject to a wide range of variables, so caution should always be exercised during or after the consumption of alcohol.
