Drug Formulary

The drug formulary (preferred drug) list indicates which medications are covered and which tier the medication applies to.  The tiers on the formular are structured as follows:

  • Tier 0:  certain preventive medications (ACA, certain statins, Metformin, and Omeprazole)
  • Tier 1:  low cost, high value generics and select brands that provide high clinical value.
  • Tier 2:  preferred brands and select generics that are less cost effective.
  • Tier 3:  non-preferred brands and generics that provide the least value because of high cost or low clinical value, or both.
  • Tier 4:  specialty medications for certain chronic illnesses or complex conditions.


Mail Order Pharmacy

Prescription drugs may be obtained through the Plan at either a local retail pharmacy (up to a 34 or 90 day supply) or through a mail order pharmacy (90 day supply).  Members who use certain maintenance or long term medications can experience a significant cost savings when filling their prescriptions for a 90 day supply.
