Oth psychoactive substance abuse w sleep disorder

This code signifies a patient's problematic pattern of psychoactive substance use, excluding alcohol and tobacco, that leads to clinically significant impairment or distress. This abuse is directly linked to the development of a sleep disorder, such as insomnia or hypersomnia, that would not otherwise be present. The substance use is not at a level meeting criteria for dependence.

Apply this code when documentation clearly indicates abuse of a psychoactive substance (e.g., cannabis, opioids, sedatives, stimulants) and a direct causal link to a sleep disturbance. This diagnosis requires evidence of a maladaptive pattern of substance use and the presence of a sleep disorder that developed during or within one month of substance intoxication or withdrawal.

• Ensure documentation specifies "abuse" and not "dependence" for the psychoactive substance.
• Verify the sleep disorder is explicitly stated as "substance-induced" and not a pre-existing condition exacerbated by substance use.
• Always code the specific psychoactive substance abused (e.g., F11.182 for opioid abuse with opioid-induced sleep disorder) when known, as F19.182 is for "other" or unspecified psychoactive substances.
