Comment:

Headache with the features of 1.4.1 Status migrainosus may often be caused by medication overuse. When headache in these circumstances meets the criteria for 8.2 Medication-overuse headache, code for this disorder and the relevant type or subtype of migraine but not for 1.4.1 Status migrainosus. When overuse of medication is of shorter duration than 3 months, code for the appropriate migraine type or subtype(s) only.
