Code based on current severity:  Note for ICD-10-CM codes: If an alcohol intoxication,
alcohol withdrawal, or another alcohol-induced m ental disorder is also present, do not use
the codes below for alcohol use disorder. Instead, the comorbid alcohol use disorder is
indicated in the 4th character of the alco hol-induced disorder code (see the coding note
for alcohol intoxication, alcohol withdrawal, or a specific alcohol-induced mental disorder).
For example, if there is comorbid alcohol intoxication and alcohol use disorder, only the
alcohol intoxication code is given, with the 4th character indicating whether the comorbid
alcohol use disorder is mild, moderate, or severe: F10.129 for mild alcohol use disorder
with alcohol intoxication or F10.229 for a moderat e or severe alcohol use disorder with al-
cohol intoxication.
Specify current severity:
305.00 (F10.10) Mild:  Presence of 2–3 symptoms.
303.90 (F10.20) Moderate: Presence of 4–5 symptoms.
303.90 (F10.20) Severe:  Presence of 6 or more symptoms.
