Mail Service Pharmacy

Blue Cross Blue Shield of Massachusetts has chosen Express Scripts®' as our mail service pharmacy. If your plan includes a benefit for the mail service pharmacy, you can order up to a 90-day supply for most long-term medications, which can save you time. You also can save money because you'll have a smaller copayment for most medications when you purchase them through the mail service pharmacy instead of a retail pharmacy.

$9 Generic Medications Available at Mail Service Pharmacy
Some prescription generic medications cost only $9 for a 90-day supply when purchased through the Express Scripts mail service pharmacy.
