Code Description

ICD-10 G43.831 is a billable code used to indicate a diagnosis of menstrual migraine, intractable, with status migrainosus.

Key Diagnostic Point:

Menstrual migraine is a type of migraine that is closely linked to the menstrual cycle, typically occurring in women during the premenstrual phase or around the onset of menstruation. Intractable menstrual migraine refers to migraines that are resistant to standard treatment protocols and can lead to prolonged episodes of severe headache, known as status migrainosus, which lasts for more than 72 hours. This condition can significantly impact a patient's quality of life, leading to missed workdays and decreased productivity. The pathophysiology involves hormonal fluctuations, particularly estrogen, which can trigger migraine attacks. Patients may experience a range of symptoms including unilateral throbbing pain, nausea, vomiting, and sensitivity to light and sound. Effective management often requires a combination of acute treatments to relieve symptoms and preventive strategies to reduce the frequency and severity of attacks. Understanding triggers, such as stress, dietary factors, and hormonal changes, is crucial for effective management.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Differentiating between menstrual and non-menstrual migraines
  • Identifying intractable cases that require specific documentation
  • Understanding the implications of status migrainosus
  • Navigating treatment protocols and their documentation

Audit Risk Factors

  • Insufficient documentation of menstrual cycle timing
  • Lack of evidence for intractability in treatment notes
  • Failure to document associated symptoms of status migrainosus
  • Inconsistent coding of migraine types

Specialty Focus

Neurology

Documentation Requirements

Detailed headache diaries, treatment response records, and menstrual cycle logs.

Common Clinical Scenarios

Patients presenting with recurrent headaches that coincide with menstrual cycles, requiring evaluation of treatment efficacy.

Billing Considerations

Neurologists must ensure comprehensive documentation of all migraine characteristics and treatment history.

Obstetrics/Gynecology

Documentation Requirements

Menstrual history, hormonal treatment records, and any relevant gynecological evaluations.

Common Clinical Scenarios

Women experiencing severe migraines linked to hormonal changes, often requiring multidisciplinary management.

Billing Considerations
