Primary hypersomnia
ICD-10 F51.11 is a billable code used to indicate a diagnosis of primary hypersomnia.
Primary hypersomnia is a sleep disorder characterized by excessive daytime sleepiness that is not attributable to other sleep disorders, medical conditions, or psychiatric disorders. Patients with primary hypersomnia often experience prolonged nighttime sleep but still feel excessively sleepy during the day. This condition can significantly impair daily functioning, affecting work, social interactions, and overall quality of life. The etiology of primary hypersomnia is not fully understood, but it may involve genetic, neurobiological, and environmental factors. Diagnosis typically requires a thorough clinical evaluation, including sleep history, sleep studies, and ruling out other potential causes of hypersomnia. Treatment options may include lifestyle modifications, stimulant medications, and behavioral therapies. It is essential for healthcare providers to differentiate primary hypersomnia from other sleep disorders, such as narcolepsy or sleep apnea, to ensure appropriate management.
