In simple words: Hypersomnia due to a medical condition means you sleep too much and have trouble staying awake because of another health problem.You might feel very sleepy during the day, even if you've slept a lot. This can be caused by things like problems with your nervous system or depression.

Hypersomnia due to a medical condition is a sleep disorder characterized by excessive daytime sleepiness and difficulty staying awake, even after getting adequate sleep. This condition is caused by an underlying medical issue, such as autonomic nervous system dysfunction or depression. Symptoms may include a strong desire to sleep during the day, difficulty waking up, prolonged sleep episodes, feelings of disorientation upon waking, anxiety, irritation, low energy, restlessness, slow thinking and speech, loss of appetite, hallucinations, and memory problems. Diagnosis typically involves medical and sleep history review, physical examination, blood tests, CT scans, and sleep studies (polysomnography). Treatment may include medications like stimulants, clonidine, levodopa, bromocriptine, antidepressants, and monoamine oxidase inhibitors, targeting the underlying medical condition.

Example 1: A patient with diagnosed Parkinson's disease experiences excessive daytime sleepiness, difficulty concentrating, and an inability to stay awake during work meetings. After a complete evaluation, the physician determines the hypersomnia is a result of the Parkinson's disease., A patient with multiple sclerosis reports significant fatigue and an overwhelming need to sleep multiple times throughout the day. The neurologist attributes the hypersomnia to the underlying MS., A patient being treated for hypothyroidism complains of persistent fatigue and prolonged sleep episodes. The endocrinologist determines that the patient's hypersomnia is a symptom of their poorly managed thyroid condition. After adjusting the medication, the hypersomnia resolves.

Documentation should include details about the patient's sleep patterns, such as sleep duration, frequency of naps, and any difficulty waking up. Additionally, the documentation should specify the underlying medical condition causing the hypersomnia and how it contributes to the sleep disturbance. Any diagnostic tests performed, such as polysomnography or other sleep studies, should also be documented. Finally, the treatment plan, including medication or therapy, should be clearly outlined in the patient's medical records.

** Always code the underlying medical condition causing the hypersomnia in addition to G47.14. The diagnosis requires a comprehensive evaluation to rule out other sleep disorders and mental health conditions. Hypersomnia due to medical conditions can significantly impact a patient's quality of life and daily functioning.
