Some of our plans provide a different level of coverage for drugs on our Specialty Drug List. With some plans, members must use CVS/specialty, our preferred specialty pharmacy vendor. CVS/specialty is a division of CVS Health, an independent company that provides pharmacy benefit management and specialty pharmacy services on behalf of BlueCross. Contact CVS/specialty by calling 800-237-2767 or faxing 800-323-3445. Some specialty drugs require prior authorization. To request prior authorization, contact CVS/specialty by calling 800-237-2767 or faxing 866-249-6155.
