Code Description

ICD-10 G47.59 is a billable code used to indicate a diagnosis of other parasomnia.

Key Diagnostic Point:

G47.59 refers to other parasomnias, which are disorders characterized by abnormal behaviors, movements, or experiences that occur during sleep. These can include sleepwalking, night terrors, and REM sleep behavior disorder, among others. Parasomnias can disrupt sleep and may lead to injury or distress for the individual or their bed partner. The diagnosis of parasomnia requires a thorough clinical evaluation, often including a sleep study (polysomnography) to differentiate these disorders from other sleep-related issues such as sleep apnea or narcolepsy. The clinical presentation can vary widely, with some individuals experiencing episodes infrequently while others may have recurrent events. Treatment options may include lifestyle modifications, medication, and addressing underlying sleep disorders. Accurate diagnosis and coding are essential for effective management and reimbursement, as these conditions can significantly impact quality of life and overall health.

  • Differentiation from other sleep disorders like sleep apnea and narcolepsy.
  • Potential overlap with psychiatric conditions.

Audit Risk Factors

  • Inadequate documentation of sleep study results.
  • Failure to specify the type of parasomnia.
  • Misdiagnosis due to overlapping symptoms with other sleep disorders.
  • Lack of patient history regarding sleep patterns.
