Sedative, hypnotic or anxiolytic use, unsp w mood disorder

This code signifies an unspecified pattern of sedative, hypnotic, or anxiolytic substance use that has directly resulted in a mood disorder. The patient exhibits symptoms of a mood disturbance (e.g., depression, anxiety, irritability) that are judged to be physiologically caused by the substance use. The specific substance or pattern of use is not documented or is unknown.

Apply this code when documentation clearly links a patient's mood disorder to their use of sedatives, hypnotics, or anxiolytics, but the specific substance or details of use are not specified. This is appropriate when the clinician explicitly states "substance-induced mood disorder" and identifies the inducing substance class as sedative/hypnotic/anxiolytic, without further detail. Supporting documentation would include a psychiatric evaluation noting the mood symptoms and the causal relationship to the unspecified substance use.

• Ensure the documentation explicitly states a causal link between the substance use and the mood disorder.
• Do not use this code if the specific sedative, hypnotic, or anxiolytic substance is identified; instead, use a more specific code from the F13.xx category.
• Sequence this code as the primary diagnosis when the substance-induced mood disorder is the focus of the encounter.
