Hypersomnia not due to a substance or known physiological condition
ICD-10 F51.1 is a billable code used to indicate a diagnosis of hypersomnia not due to a substance or known physiological condition.
Hypersomnia not due to a substance or known physiological condition is characterized by excessive daytime sleepiness that is not attributable to any substance use or identifiable medical condition. Patients may experience prolonged sleep episodes, difficulty waking up, and a persistent need for sleep that interferes with daily activities. This condition can significantly impact quality of life, leading to difficulties in occupational and social functioning. It is essential to differentiate hypersomnia from other sleep disorders, such as narcolepsy or sleep apnea, as well as from conditions like depression or anxiety that may also contribute to excessive sleepiness. Diagnosis typically involves a thorough clinical evaluation, including sleep history, sleep diaries, and possibly polysomnography to rule out other sleep disorders. Treatment may include lifestyle modifications, cognitive behavioral therapy, and pharmacological interventions aimed at managing symptoms and improving wakefulness.
