What is a Preferred Drug List (PDL)?
The Preferred Drug List is a list of the most commonly prescribed generic drugs and preferred brand-name drugs. The preferred drug list is subject to change and is periodically updated. Generic drugs are covered at the Tier 1 co-pay level. Preferred brand-name drugs are covered at the Tier 2 co-pay level. Other brand-name drugs are covered by your plan, but are considered non-preferred. Non-preferred brand name drugs are covered at the Tier 3 co-pay level.
