Under the plan, Tier 1 drugs are offered at a higher reimbursement level than other medications. Tier 1 is a defined list of drugs that are clinically proven and cost-effective. Tier 2 drugs have a lower reimbursement level. For example, Tier 1 drugs are covered 100% under CSI’s Flex 1 plan, and Tier 2 drugs are covered at 80%. By separating drugs into 2 tiers, DTF incorporates the cost-saving benefits of a managed drug plan without eliminating coverage for other medications.
Higher reimbursement for preferred DTF drug therapies encourages you to use more cost effective drugs while still providing the flexibility to choose most other prescription drugs at a lower reimbursement level. Additional savings can be generated if you switch your existing medications to lower cost DTF alternatives.
