Prescription drugs (Aetna and Horizon)

Prescription drug coverage

If you enroll in a medical plan through Aetna or Horizon Blue Cross Blue Shield, your prescription drug benefits will be provided by Express Scripts. You can visit express-scripts.com to find a pharmacy near you.

Use your Express Scripts identification card when purchasing any prescriptions to ensure you are charged the correct amount. If you have any questions, please call Express Scripts at 1-866-544-6884.

If you enroll in a medical plan through Kaiser, you will use the same identification card for both medical and prescription expenses.

The amount you pay for prescription drugs depends on the type of drug and how you fill your prescriptions. 

Drug types 
  • Generic drugs: Same active ingredients as brand-name equivalents and meet the same standards for quality and effectiveness but cost much less.

  • Preferred drugs: Brand-name medications included on the formulary based on effectiveness and cost. 

  • Non-preferred drugs: Brand-name medications not preferred by your carrier. They may still be covered but may require prior authorization and cost more.

The pharmacy plans available under Kaiser vary and they work a little differently than the other carriers’ plans. For details, visit the Chubb Benefits Portal.

Filling prescriptions

If you are filling a prescription for a medication that you will be taking for the short term, take your Express Scripts ID with you to any participating pharmacy (such as your local grocery store or drug store) and fill your prescription. If you take any maintenance medications (for example, to manage your cholesterol or lower your blood pressure), you may get a 90-day supply through the mail-order program or pick up your medication at a participating local Walgreens retail pharmacy. Not filling a 90-day supply at Walgreens after exhausting your two grace retail fills may require that you pay the full price of the medication.

Please note that this program is not available to Kaiser members; more information about Kaiser prescription benefits is available on the Chubb Benefits Portal.
