291.9
ICD-9-CMThis code represents a mental disorder that is directly caused by alcohol consumption, but the specific type of mental disorder is not documented or cannot be determined. It encompasses a range of psychiatric symptoms, such as hallucinations, delusions, or mood disturbances, where alcohol is the clear etiologic factor.
Use this code when a patient presents with mental health symptoms clearly attributed to alcohol, but the physician's documentation does not specify a more precise alcohol-induced mental disorder (e.g., alcohol withdrawal delirium, alcohol-induced psychotic disorder). Documentation should explicitly link the mental symptoms to alcohol use, but lack specificity regarding the exact diagnosis.
