Chronic migraine without aura, not intractable, without status migrainosus
ICD-10 G43.709 is a billable code used to indicate a diagnosis of chronic migraine without aura, not intractable, without status migrainosus.
Chronic migraine without aura is characterized by the occurrence of 15 or more headache days per month, with at least 8 of those days meeting the criteria for migraine. Unlike migraines with aura, patients do not experience neurological symptoms such as visual disturbances or sensory changes prior to the headache. This condition is classified as not intractable, meaning that the migraines are manageable and do not lead to prolonged episodes of severe headache that require emergency intervention (status migrainosus). Chronic migraines can significantly impact a patient's quality of life, leading to functional impairment and decreased productivity. Common triggers include stress, hormonal changes, dietary factors, and environmental stimuli. Preventive treatments may include pharmacological options such as beta-blockers, anticonvulsants, and antidepressants, as well as non-pharmacological strategies like lifestyle modifications and cognitive behavioral therapy.

Patients presenting with frequent headaches, seeking preventive treatment options.
Neurologists must document the absence of aura and the frequency of headaches to support the diagnosis.
Comprehensive history and physical examination, including trigger identification.
Patients with chronic headaches seeking management strategies.
Primary care providers should ensure thorough documentation of lifestyle factors and treatment responses.

Neurologists may require more detailed neurological examinations.
Chronic migraine occurs 15 or more days per month, while episodic migraine occurs fewer than 15 days per month. Chronic migraines can lead to more significant disability and require different management strategies.
