Special Requirements

Within the Formulary, you will see which drugs may have special requirements including –

  • Prior Authorization – Some medications need approval by the Pharmacy Department before Senior Preferred will cover them.
  • Step Therapy – some prescription drugs require Step Therapy. Step Therapy means that you have to try one or more drugs first, before Senior Preferred will cover the prescribed drug.
  • Quantity Limits – Some prescriptions have limits on how much of the medicine covered per prescription. It can also mean that you can only get a specific amount of the drug within a period of time. 

P&T Committee

The drugs on the Senior Preferred Formulary are selected with help from the Pharmacy and Therapeutics (P&T) Committee. The P&T Committee is team of health care providers. The Formulary is made up of medicines that are a necessary part of a quality treatment program.

Senior Preferred will generally cover the drugs listed in our Formulary as long as the drug is

  • medically necessary
  • the prescription is filled at a Senior Preferred network pharmacy
  • other plan rules are followed

For more information on how to fill your prescriptions, please review your Evidence of Coverage (EOC). You can view your plan documents, including the EOC by logging into MyChart.

Brand and Generic Drugs

Senior Preferred covers both brand name drugs and generic drugs within the Formulary. Generic drugs have the same active-ingredient formula as a brand name drug. Generic drugs usually cost less than brand name drugs and are rated by the Food and Drug Administration (FDA) to be as safe and effective as brand name drugs.     

Updating the Formulary

Formulary development and maintenance is an ongoing process. The P&T Committee regularly reviews new and existing medications to ensure the Formulary remains responsive to the needs of our members and providers. The Formulary is updated periodically and changes are able to be seen by clicking on the Part D Drug Formulary link above.
