Y90: Evidence of alcohol involvement determined by blood alcohol level

Y90.2: Blood alcohol level of 40-59 mg/100 ml

Blood alcohol level of 40-59 mg/100 ml refers to a condition where the concentration of alcohol in a person's blood is within this specific range. This level of alcohol in the bloodstream commonly arises after moderate drinking. At this blood alcohol concentration, an individual may experience some subtle physical and mental effects, such as modest impairment of judgment and a slight decrease in the speed of motor control. These effects might not be apparent to the person drinking, but can affect tasks that require careful concentration and coordination, such as driving a car or operating machinery. This level of intoxication is typically temporary, and it decreases over time as the body metabolizes the alcohol. It is important to note that effects can vary greatly between individuals, influenced by factors such as weight, tolerance to alcohol, and the presence of food in the stomach.
