Code Description

ICD-10 G47.5 is a billable code used to indicate a diagnosis of parasomnia.

Key Diagnostic Point:

Parasomnia refers to a group of sleep disorders characterized by abnormal behaviors, movements, emotions, perceptions, and dreams that occur during sleep. These disorders can manifest in various forms, including sleepwalking, night terrors, and REM sleep behavior disorder. Patients may experience episodes that disrupt their sleep or that of others, leading to potential safety concerns. Parasomnias can be triggered by factors such as stress, sleep deprivation, or certain medications. The diagnosis often requires a thorough sleep history and may involve polysomnography (sleep study) to observe the patient's sleep patterns and behaviors. Treatment options vary based on the specific type of parasomnia and may include lifestyle changes, medication, or therapy. Understanding the nuances of parasomnia is crucial for accurate coding and effective management of the condition.
