Blood alcohol level of 100-119 mg/100 ml

This code indicates a documented blood alcohol concentration (BAC) between 100 and 119 milligrams per 100 milliliters (mg/dL). This level is above the legal limit for driving in most jurisdictions and is associated with impaired judgment, coordination, and reaction time.

Apply this code when a patient's medical record explicitly states a BAC within the 100-119 mg/dL range, often obtained through laboratory testing. This is typically used in cases of alcohol intoxication, alcohol-related injuries, or when alcohol consumption is a contributing factor to the patient's presentation.

• Always confirm the exact BAC value from laboratory results or physician documentation.
• Do not assign this code if the BAC is outside the specified range; use the appropriate Y90 code for other levels.
• This code is a secondary diagnosis and should be sequenced after the primary condition or injury.
