Excessive blood level of alcohol

This code signifies a laboratory finding indicating an elevated concentration of ethanol in the bloodstream, exceeding normal physiological levels. It represents objective evidence of recent alcohol consumption that has resulted in a measurable systemic presence of alcohol. This finding is often associated with acute alcohol intoxication.

This code is appropriate when laboratory results confirm a blood alcohol content (BAC) above the established legal or clinical thresholds for intoxication or impairment. It should be used when documentation explicitly states "excessive blood alcohol level," "elevated BAC," or provides a specific BAC measurement indicating an abnormal level. This code is typically used in emergency department settings, toxicology screenings, or when evaluating acute alcohol-related presentations.

• Do not use this code for a history of alcohol abuse or dependence; those require specific substance abuse codes.
• Ensure documentation clearly states a measured excessive blood alcohol level, not just clinical suspicion of intoxication.
• This code can be a principal diagnosis if the excessive blood alcohol is the primary reason for the encounter, or a secondary diagnosis if it's an associated finding.
