Y90: Evidence of alcohol involvement determined by blood alcohol level
The group of conditions indicated by the Y90 code are primarily linked to the presence of alcohol in a person's blood. These conditions arise when a person consumes alcoholic drinks, leading to the absorption of alcohol into their blood. The alcohol level can vary widely, with higher levels generally indicative of more severe consumption. The typical signs of these conditions include altered behavior, thinking, and motor coordination. These changes can sometimes progress to more alarming symptoms such as unconsciousness, depending on the blood alcohol level. Potentially every bodily system can be affected, particularly the liver and the nervous system. The progression of these conditions largely depends on the frequency and volume of alcohol consumed.
