Blood alcohol level of 80-99 mg/100 ml

This code indicates a blood alcohol concentration (BAC) between 80 and 99 milligrams per 100 milliliters (mg/dL). This range is often associated with impaired judgment, decreased coordination, and slowed reaction times, and is at or above the legal limit for driving under the influence in many jurisdictions.

This code is used when documentation explicitly states a patient's BAC falls within the 80-99 mg/100 ml range. It is frequently applied in cases of acute alcohol intoxication, motor vehicle accidents, or other incidents where alcohol consumption is a contributing factor and the specific BAC is known.

• Ensure the documentation clearly specifies the exact blood alcohol level within the 80-99 mg/100 ml range.
• Do not use this code if the documentation only states "positive for alcohol" without a specific quantitative level.
• Always sequence this code as a secondary diagnosis, following the primary reason for the encounter.
