RxHCCHCC 166 — Migraine
0.000What This Code Means
A migraine with warning signs (aura) that responds to treatment but is currently in a prolonged migraine state lasting more than 72 hours.
Coding Tips
- •Status migrainosus is a medical emergency; ensure this condition is clearly documented in the medical record
- •Not intractable means the migraine typically responds to standard treatments despite current status
Clinical Significance
Migraine with aura and status migrainosus involves a migraine preceded by visual, sensory, or speech disturbances that has progressed to a continuous state lasting over 72 hours. The aura component is clinically significant because it may mimic stroke or transient ischemic attack symptoms, requiring careful differential diagnosis. Status migrainosus in this context often necessitates emergency or inpatient management.
Documentation Requirements
- ✓Confirmed migraine with aura diagnosis with description of aura type (visual, sensory, speech)
- ✓Status migrainosus documented with continuous migraine duration exceeding 72 hours
- ✓Statement that migraines generally respond to treatment (not intractable)
- ✓Differentiation from stroke or transient ischemic attack documented
- ✓Emergency or inpatient treatments provided
