When your doctor decides you should take a medicine that requires Prior Authorization (PA), he or she must ask about it first. This is called Prior Authorization because your doctor has to get approval before the medicine is covered. MDwise works with a company called MedImpact for pharmacy benefits and prior authorization. A team at MedImpact will review the PA request from your doctor. You can contact MedImpact at 844-336-2677 for more information about Prior Authorization. Your doctor can also contact MedImpact or visit the MDwise website for a PA form. Visit myMDwise at MDwise.org/myMDwise where you can sign up to get more information about your coverage and claims. You can also call MDwise customer service at 1-800-356-1204 8 a.m. to 8 p.m. EST, Monday through Friday if you have questions about your benefits.
