Y91.1: Moderate alcohol intoxication

Moderate alcohol intoxication, denoted by ICD-10 code Y91.1, is a medical condition characterized by a significant impairment due to alcohol consumption, but without the stupor or unconsciousness associated with severe intoxication. This condition mainly presents after consuming an amount of alcohol that raises the blood alcohol concentration to a level that exceeds the legal or customary standards in most jurisdictions. Some common symptoms include impairments in speech, balance, reaction time, and gross motor control along with potential emotional instability. These physical and mental changes may lead to altercations, falls, or accidents, posing a risk to both the individual and others around them. This level of intoxication can also impact cognitive functions, making it harder for the individual to make rational decisions, potentially leading to hazardous situations. Moreover, continuous episodes of moderate alcohol intoxication may progress to alcohol abuse or dependence, having long-term effects on various bodily systems, including the liver, heart, and nervous systems.
