Oth psychoactive substance dependence w sleep disorder

This code signifies a patient's physiological and psychological dependence on a psychoactive substance (excluding alcohol, opioids, cannabis, sedatives, hypnotics, anxiolytics, stimulants, and hallucinogens) that has led to the development of a sleep disorder. The sleep disturbance is directly attributable to the effects of the substance use.

Apply this code when documentation clearly indicates dependence on a specified "other" psychoactive substance, and a causal link is established between this substance use and an observed sleep disorder. Supporting documentation should detail the specific psychoactive substance (e.g., inhalants, other unspecified substances) and the nature of the substance-induced sleep disturbance (e.g., insomnia, hypersomnia, parasomnia).

• Always code the specific psychoactive substance if known and documented (e.g., F18.282 for inhalant dependence). This code is for "other" or unspecified psychoactive substances.
• Ensure the documentation explicitly states "dependence" and not just "abuse" or "use," as these have different code assignments.
• Verify that the sleep disorder is explicitly linked as "substance-induced" by the psychoactive substance, rather than a co-occurring but unrelated sleep disorder.
