Patient presents with a complaint of migraine headache during pregnancy.  The onset, duration, and character of the headache were documented.  Symptoms such as throbbing pain, unilateral location, moderate to severe intensity, pulsating quality, aggravation by routine physical activity, and associated features like nausea, vomiting, photophobia, and phonophobia were assessed and recorded.  The patient's obstetric history, including gestational age and trimester, was noted.  A neurological examination was performed to rule out other potential causes of headache, such as pre-eclampsia, stroke, or intracranial pathology.  Differential diagnoses considered included tension-type headache, cluster headache, and secondary headaches.  The diagnosis of migraine in pregnancy was made based on the International Classification of Headache Disorders (ICHD-3) criteria.  The patient's medical history, including pre-pregnancy migraine history and current medications, was reviewed.  Management options for migraine during pregnancy were discussed, focusing on non-pharmacological approaches such as lifestyle modifications, stress reduction techniques, and biofeedback.  Pharmacological options, including acetaminophen, were considered, taking into account fetal safety guidelines and potential risks.  The patient was counseled on the importance of close monitoring and follow-up.  Appropriate ICD-10 and CPT codes for migraine in pregnancy, headache in pregnancy, and antenatal care were documented for billing and coding purposes.  The plan includes patient education on migraine triggers, preventative measures, and appropriate use of abortive medications during pregnancy.  The patient was advised to return for further evaluation if symptoms worsen or change.
