Oth psychoactive substance use, unsp w sleep disorder

This code signifies a patient's problematic pattern of using a psychoactive substance (other than alcohol, opioids, cannabis, sedatives, hypnotics, anxiolytics, stimulants, hallucinogens, or inhalants) that has led to the development of a sleep disorder. The specific psychoactive substance involved is not documented or is unknown. The sleep disturbance is directly attributable to the substance use.

Apply this code when documentation indicates a patient is experiencing a sleep disorder directly induced by the use of an unspecified "other" psychoactive substance. This typically involves a clear causal link established by the clinician, where the sleep disturbance began during or soon after substance intoxication or withdrawal. Supporting documentation should clearly state the presence of both the substance use and the induced sleep disorder, and the specific substance should not be identifiable from other ICD-10-CM categories.

• Ensure the documentation explicitly links the sleep disorder to the psychoactive substance use.
• Only use this code when the specific "other" psychoactive substance cannot be identified. If the substance is known (e.g., caffeine, anabolic steroids), a more specific code from the F19.xx category or another F1x.xx category should be used.
• This code requires a causal relationship; simply having both substance use and a sleep disorder is not sufficient without the documented link.
