Code Description

ICD-10 G47.411 is a billable code used to indicate a diagnosis of narcolepsy with cataplexy.

Key Diagnostic Point:

Narcolepsy with cataplexy is a chronic neurological disorder characterized by excessive daytime sleepiness and sudden episodes of muscle weakness (cataplexy) triggered by strong emotions such as laughter, anger, or surprise. Patients may experience disrupted nighttime sleep, vivid hallucinations, and sleep paralysis. The condition is caused by a deficiency of hypocretin (orexin), a neurotransmitter that regulates wakefulness and REM sleep. Diagnosis typically involves a comprehensive sleep study (polysomnography) and a multiple sleep latency test (MSLT) to assess the degree of daytime sleepiness and the presence of REM sleep during naps. Treatment options include lifestyle modifications, stimulant medications to promote wakefulness, and sodium oxybate to manage cataplexy. Accurate coding is essential for appropriate reimbursement and to reflect the complexity of the patient's condition.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between narcolepsy types (with and without cataplexy)
  • Need for comprehensive sleep study results for accurate diagnosis
  • Potential overlap with other sleep disorders (e.g., sleep apnea)
  • Documentation of emotional triggers for cataplexy

Audit Risk Factors

  • Inadequate documentation of cataplexy episodes
  • Failure to include sleep study results
  • Misclassification of narcolepsy type
  • Lack of evidence for emotional triggers
