Migraine, unsp, not intractable, with status migrainosus

This code signifies a migraine headache of an unknown type that is not resistant to treatment and has progressed to status migrainosus. Status migrainosus is a severe, debilitating migraine attack lasting longer than 72 hours, often requiring hospitalization. The specific characteristics of the migraine (e.g., with or without aura) are not documented or are unknown.

Apply this code when documentation clearly indicates an unspecified migraine that has evolved into status migrainosus, and the condition is not noted as intractable. This is typically used for patients presenting with prolonged, severe migraine symptoms unresponsive to initial outpatient management, leading to an inpatient admission or emergency department visit for aggressive treatment. Documentation should explicitly state "status migrainosus" and lack any mention of intractability or specific migraine type.

• Do not use this code if the migraine type (e.g., with aura, without aura) is specified in the documentation; instead, select a more specific G43 subcategory.
• Ensure documentation explicitly states "status migrainosus" and "not intractable" to support this code.
• Avoid using this code if the migraine is described as intractable; refer to codes with the "intractable" designation.
