Y90: Evidence of alcohol involvement determined by blood alcohol level

Y90.9: Presence of alcohol in blood, level not specified

The Presence of alcohol in the blood, with the level not specified, typically refers to a certain concentration of alcohol detected in a person's bloodstream, even though the specific quantity is not determined. Alcohol, after consumption, is absorbed into the bloodstream, where it can then affect the nervous system, which encompasses the brain and nerve tissues. This can impact physical coordination, cognitive function, emotional state, and overall consciousness levels. The effects can vary extensively based on a multitude of factors such as the person's size, body chemistry, the type and amount of alcohol consumed, and the rate at which it's consumed. The presence of alcohol in the blood may be identified through a blood test, usually administered to determine if a person is legally intoxicated, especially in cases related to driving under influence (DUI) or other alcohol-related incidents.
