The Caterpillar Drug Formulary is the list of medications covered by the plan. If a medication isn't on the formulary, it's not covered, which means you pay 100% of the cost (another idea: ask your doctor for an alternative option).

$AVE MONEY WITH TIER 0 MEDICATIONS
Medications on the $0 Prescription Drug List have been determined to be "best in class" and most cost-effective, so they're offered for a $0 co-pay.
Paying for a higher-tier medication? You may want to talk to your doctor to see if a Tier 0 medication would be an appropriate replacement.
