  2. Initial Coverage Phase: copays up to 25% of the cost of the prescription.
  3. Coverage Gap Phase: Also known as the Donut Hole. Once your drug cost reaches a certain amount, you’ll be required to pay 25% of the cost of your scripts.
  4. Catastrophic Phase: Once you’ve paid a certain amount out of pocket, you’re responsible for the greater of 5% of the cost of the scripts or $9.21 (Brand Name Drugs) and $3.70 (Generic Drugs)
