Code Description

ICD-10 G47.0 is a billable code used to indicate a diagnosis of insomnia.

Key Diagnostic Point:

Insomnia is a sleep disorder characterized by difficulty falling asleep, staying asleep, or waking up too early and not being able to return to sleep. It can be classified into acute or chronic forms, with chronic insomnia lasting for at least three times a week over a period of three months or longer. The condition can be primary, where it is not attributable to any other medical or psychiatric disorder, or secondary, where it is a symptom of another condition such as anxiety, depression, or chronic pain. Insomnia can lead to significant daytime impairment, including fatigue, mood disturbances, and cognitive dysfunction. The diagnosis is typically made through patient history, sleep diaries, and sometimes polysomnography or other sleep studies to rule out other sleep disorders such as sleep apnea or restless leg syndrome. Treatment options may include cognitive behavioral therapy for insomnia (CBT-I), pharmacotherapy, or lifestyle modifications. Understanding the underlying causes and associated conditions is crucial for effective management.
