ICD Code G43.709

ICD code G43.709 is used to classify a diagnosis of chronic migraine without aura, which is not intractable and does not involve status migrainosus. This means the patient experiences frequent migraine headaches that do not include sensory disturbances known as auras, are manageable with treatment, and do not escalate into a prolonged and severe migraine attack known as status migrainosus.

1. Chronic Headache History: The patient has experienced headaches for 15 or more days per month over a period of at least three months.

2. Migraine Characteristics: The headaches exhibit migraine features such as unilateral location, pulsating quality, moderate to severe pain intensity, and aggravation by or causing avoidance of routine physical activity.

3. Absence of Aura: The patient does not experience any aura symptoms, such as visual disturbances or sensory changes, before the onset of the headache.

4. Non-Intractable: The migraine is manageable with standard treatment options and does not require specialized interventions for relief.

5. Without Status Migrainosus: The migraine episodes do not persist for more than 72 hours, and there is no prolonged migraine attack that requires emergency intervention.

6. Exclusion of Other Causes: Other potential causes of chronic headaches, such as medication overuse or secondary headaches due to other medical conditions, have been ruled out.

7. Impact on Daily Life: The chronic migraines significantly impact the patient's daily activities and quality of life, necessitating ongoing management and treatment.
