may relate to alcohol use disorder as well. At least a part of the reported association between
depression and moderate to severe alcohol use disorder may be attributable to temporary, al-
cohol-induced comorbid depressive symptoms re sulting from the acute effects of intoxication
or withdrawal. Severe, repeated  alcohol intoxication may also suppress immune mechanisms
and predispose individuals to infections and increase the risk for cancers.

Coding note:  The ICD-9-CM code is 303.00.  The ICD-10-CM code depends on whether
there is a comorbid alcohol use disorder. If a mild alcohol use disorder is comorbid, the
ICD-10-CM code is F10.129,  and if a moderate or severe alcohol use disorder is comorbid,
the ICD-10-CM code is F10.229.  If there is no comorbid alcohol use disorder, then the
ICD-10-CM code is F10.929.
