Oth stimulant use, unsp w stimulant-induced sleep disorder

This code signifies a diagnosis of stimulant use disorder, not otherwise specified, where the patient is experiencing a sleep disturbance directly attributable to their stimulant use. This includes conditions like insomnia or hypersomnia that are clearly induced by the stimulant.

Apply this code when documentation confirms a patient's stimulant use and a co-occurring sleep disorder that the clinician explicitly links as stimulant-induced. This is appropriate when the specific stimulant is not documented or cannot be determined.

• Ensure the documentation clearly states the sleep disorder is "stimulant-induced" and not merely co-occurring.
• If the specific stimulant is known (e.g., amphetamine, methamphetamine), use a more specific code from the F15.xx series.
• Sequence this code as the primary diagnosis if the stimulant-induced sleep disorder is the main reason for the encounter.
