Code Description

ICD-10 G43.119 is a billable code used to indicate a diagnosis of migraine with aura, intractable, without status migrainosus.

Key Diagnostic Point:

Migraine with aura, intractable, without status migrainosus refers to a severe form of migraine characterized by the presence of neurological symptoms (aura) that precede or accompany the headache. This condition is classified as intractable, meaning it is resistant to standard treatment protocols and results in significant impairment in daily functioning. Patients may experience recurrent episodes of headache that can last from 4 to 72 hours, accompanied by symptoms such as visual disturbances, sensory changes, and speech difficulties. The absence of status migrainosus, which is defined as a migraine attack lasting longer than 72 hours, distinguishes this code from others related to prolonged migraine episodes. Triggers for these migraines can include stress, hormonal changes, certain foods, and environmental factors. Preventive treatments may involve medications such as beta-blockers, anticonvulsants, or CGRP inhibitors, and lifestyle modifications to reduce the frequency and severity of attacks.

High Complexity

Complexity Factors

  • Differentiating between types of migraines and their severity
  • Understanding the specific criteria for intractability
  • Identifying and documenting aura symptoms accurately
  • Navigating the nuances of related codes and exclusions

Audit Risk Factors

  • Inadequate documentation of aura symptoms
  • Failure to specify intractability
  • Misclassification of migraine type
  • Lack of supporting evidence for treatment plans

Specialty Focus

Medical Specialties

Neurology

Documentation Requirements

Detailed patient history, including frequency and duration of migraines, aura symptoms, and response to treatments.

Common Clinical Scenarios

Patients presenting with recurrent migraines that do not respond to standard treatments, requiring advanced management strategies.

Billing Considerations

Neurologists must ensure comprehensive documentation of neurological assessments and treatment plans to support the diagnosis of intractable migraines.

Primary Care

Documentation Requirements

Thorough documentation of patient-reported symptoms, triggers, and any prior treatments attempted.

Common Clinical Scenarios

Patients with a history of migraines presenting for management of intractable symptoms.

Billing Considerations

Primary care providers should be aware of the need for referrals to specialists when migraines are intractable.

Coding Guidelines

Inclusion Criteria

Use G43.119 When
  • According to the official coding guidelines, G43
  • 119 should be used when the patient has a documented history of migraines with aura that are intractable and not meeting the criteria for status migrainosus
  • Coders must ensure that the documentation supports the diagnosis and that the intractable nature is clearly articulated

Exclusion Criteria

Do NOT use G43.119 When
No specific exclusions found.
