Blood alcohol level of 240 mg/100 ml or more

This code indicates a significantly elevated blood alcohol concentration (BAC) of 240 milligrams per 100 milliliters or higher. This level is associated with severe alcohol intoxication, often leading to profound impairment, loss of consciousness, and a high risk of acute complications.

Assign this code when documentation explicitly states a blood alcohol level of 240 mg/100 ml or greater, or an equivalent measurement (e.g., 0.24% or 0.24 g/dL). This is typically used in cases of acute alcohol poisoning, overdose, or when alcohol intoxication is a significant contributing factor to a patient's presentation.

• Ensure the documentation clearly specifies the blood alcohol level meets or exceeds the 240 mg/100 ml threshold.
• Do not use this code if the BAC is below 240 mg/100 ml; instead, refer to other codes in the Y90 series for lower levels.
• This code is for reporting the BAC itself and should be used in conjunction with codes for the patient's specific alcohol-related conditions or injuries.
