Coding Tips

Clinical Significance
Migraine with aura, medication-responsive, without status migrainosus is the standard presentation of classic migraine. The aura phase typically involves visual phenomena (scintillating scotoma, zigzag lines), sensory symptoms, or speech difficulties lasting 5-60 minutes before headache onset. Migraine with aura carries a slightly increased stroke risk, particularly in women using estrogen-containing contraceptives.
Documentation Requirements
- ✓Confirmed migraine with aura diagnosis
- ✓Description of aura type and duration (visual, sensory, speech disturbance)
- ✓Seizure control — responding to treatment (not intractable)
- ✓Absence of status migrainosus (episodes <72 hours)
- ✓Current acute and preventive treatment regimen
- ✓Assessment of stroke risk factors if applicable (smoking, oral contraceptive use)
