In simple words: This diagnosis refers to a sleep problem caused by overuse of a stimulant drug that's not caffeine, cocaine, or amphetamine. The person is using the drug too much even though it's harming their sleep and their life.

This code signifies the abuse of a stimulant drug, not including caffeine, cocaine, or amphetamines, that leads to a sleep disorder. The individual is excessively using the stimulant despite its negative impact on their life. This diagnosis requires documentation of the specific stimulant used and the associated sleep disturbance.

Example 1: A patient is found to be abusing khat, leading to insomnia and daytime fatigue., A patient is excessively using prescription modafinil, experiencing difficulty falling asleep and restless nights., A patient admits to abusing synthetic cathinones, experiencing disrupted sleep patterns and daytime sleepiness.

Documentation should include the specific type of stimulant abused, evidence of the abuse pattern, and details about the associated sleep disorder, such as insomnia, hypersomnia, or parasomnia. Clinical findings related to sleep disturbance should be noted. It's also important to document that the sleep disorder is induced by the stimulant abuse and not another underlying condition.
