IHS Diagnosis ICD-10
1.5.2 Status migrainosus G43.2  


A debilitating migraine attack lasting for more than 72 hours.

Diagnostic criteria:

  1. The present attack in a patient with 1.1 Migraine without aura is typical of previous attacks except for its duration
  2. Headache has both of the following features:
    1. unremitting for >72 hours
    2. severe intensity
  3. Not attributed to another disorder


Interruption during sleep is disregarded. Short-lasting relief due to medication is also disregarded. Status may often be caused by medication overuse and should be coded accordingly. Non-debilitating attacks lasting >72 hours but otherwise meeting these criteria are coded as 1.6.1 Probable migraine without aura.
