Parasomnia, unspecified
ICD-10 G47.50 is a billable code used to indicate a diagnosis of parasomnia, unspecified.
Parasomnia refers to a group of sleep disorders characterized by abnormal movements, behaviors, emotions, perceptions, and dreams that occur during sleep. The unspecified designation under G47.50 indicates that the specific type of parasomnia has not been clearly identified. Common manifestations of parasomnia include sleepwalking, night terrors, and REM sleep behavior disorder. These episodes can lead to significant distress and impairment in social, occupational, or other important areas of functioning. Patients may not be aware of their behaviors during these episodes, which can complicate diagnosis and treatment. The condition can be triggered by various factors, including stress, sleep deprivation, medications, and underlying medical conditions. Accurate diagnosis often requires a thorough sleep history, clinical evaluation, and sometimes polysomnography (sleep study) to differentiate parasomnia from other sleep disorders such as sleep apnea or narcolepsy. Treatment may involve lifestyle changes, medication, or therapy, depending on the severity and frequency of episodes.
Detailed sleep history, including frequency and nature of episodes, and results from sleep studies.
Patients presenting with sleep disturbances, unexplained daytime sleepiness, or reports from family members about abnormal behaviors during sleep.
Consideration of comorbid conditions such as anxiety or depression that may exacerbate parasomnia symptoms.
Neurological evaluation to rule out other conditions, detailed patient history, and possibly EEG findings.
Patients with a history of seizures or neurological disorders presenting with sleep disturbances.
Differentiating between parasomnia and seizure activity during sleep.
Used to evaluate patients with suspected parasomnia to differentiate from other sleep disorders.
Results of the sleep study must be documented, including any observed behaviors.
Sleep specialists should ensure comprehensive reporting of findings related to parasomnia.
G47.50 is used when the specific type of parasomnia is not identified. Other codes, such as G47.51 for nightmare disorder or G47.52 for sleepwalking disorder, should be used when the specific condition is documented.
