Y90: Evidence of alcohol involvement determined by blood alcohol level

Y90.0: Blood alcohol level of less than 20 mg/100 ml

The condition identified by the ICD-10 code Y90.0 refers to having a blood alcohol level of less than 20 milligrams per 100 milliliters in one's system. This means the individual has consumed a relatively small amount of alcohol - an amount that is often insufficient to produce noticeable effects or symptoms in most individuals. Alcohol, when consumed, is absorbed into the bloodstream and can affect various body systems, especially the central nervous system, which includes the brain and spinal cord. It's important to note that alcohol affects people differently - some people may experience slight changes in mood and behavior even at low blood alcohol levels, while others may notice no effects. Factors that can influence these effects include a person's size, weight, age, sex, tolerance levels, and whether they consumed food with the alcohol.
