Code Description

ICD-10 G43.111 is a billable code used to indicate a diagnosis of migraine with aura, intractable, with status migrainosus.

Key Diagnostic Point:

Migraine with aura, intractable, with status migrainosus is a severe form of migraine characterized by the presence of aura symptoms that precede or accompany the headache phase. Aura symptoms can include visual disturbances, sensory changes, and motor deficits. This condition is classified as intractable when it does not respond to standard acute treatments and can lead to status migrainosus, a debilitating state where the migraine lasts for more than 72 hours. Patients may experience significant functional impairment, requiring urgent medical intervention. The intractable nature of this migraine type often necessitates a multidisciplinary approach for management, including pharmacological treatments such as triptans, antiemetics, and preventive therapies like beta-blockers or anticonvulsants. Understanding triggers, which can include stress, hormonal changes, certain foods, and environmental factors, is crucial for effective management and prevention of future episodes.

High Complexity

Complexity Factors

  • Intractable nature requiring specialized treatment plans
  • Differentiation from other types of migraines and headaches
  • Need for comprehensive documentation of aura symptoms
  • Potential for status migrainosus complicating treatment

Audit Risk Factors

  • Insufficient documentation of aura symptoms
  • Lack of evidence for intractability
  • Failure to document treatment attempts and responses
  • Inadequate differentiation from other headache disorders
