Blue Cross and Blue Shield of North Carolina’s Blue Medicare PPO Enhanced and Blue Medicare HMO Enhanced plans include a 6-tier prescription drug formulary. Medications in Tier 6 have NO copay.* 

Members can benefit from cost-savings opportunities when they are prescribed a medication in Tier 6.  Although this may seem confusing, as typically higher tiers are associated with higher copays, medications in Tier 6 mean the member will actually pay less.
