How does Medicare Part D coverage work?

Each Medicare Advantage plan with prescription drug coverage or Part D plan has its own list of covered drugs, called a formulary. Our pharmacy department partners with physicians from other health systems who are specialized in their field to decide which drugs to include based on quality, safety and how well they work.

Every drug listed in our formulary is put into a cost group called a tier. For the lowest tier, you pay the lowest copayment. As you move to the next tier, what you pay increases.
