Migraine with aura, not intractable, with status migrainosus

This code signifies a type of migraine headache characterized by transient neurological symptoms (aura) preceding or accompanying the headache phase. The migraine episode is not resistant to standard treatment and has progressed to a severe, debilitating state lasting more than 72 hours, often requiring hospitalization.

Use this code for patients experiencing a prolonged and severe migraine attack with associated aura that has not responded to initial outpatient treatments. Documentation should clearly indicate the presence of aura, the intractable nature of the migraine (i.e., not responding to typical abortive therapies), and the duration exceeding 72 hours, consistent with status migrainosus.

• Ensure documentation explicitly states "with aura" and "status migrainosus" to support this specific code.
• Distinguish from G43.109 (Migraine with aura, not intractable, without status migrainosus) where the prolonged, severe state is absent.
• Always review the medical record for any underlying causes or comorbidities that may require additional coding.
