Prescription coverage

Most HAP Medicare Advantage Plans include prescription drug coverage (or Part D) and a $0 annual prescription deductible.  Other highlights include $0 copay for tier 1 drugs purchased at preferred pharmacy; and a $0 copay for 90-day supply of most tier 1 and tier 2 drugs purchased from a preferred mail order pharmacy in the initial phase of coverage. Tier 6 select care drugs includes generic drugs for blood pressure, cholesterol, and diabetes at $0 cost share.

Important message about what you pay for vaccines - Our plan covers most Part D vaccines at no cost to you, even if you haven’t paid your deductible. Speak with Customer Service for more information. Call (800) 422-4641

Important message about what you pay for insulin - You won’t pay more than $35 for a one-month supply of each insulin product covered by our plan, no matter what cost-sharing tier it’s on, even if you haven’t paid your deductible.

Will my medication be covered?

The drug name will be highlighted.

To be covered by the plan, you must have your prescriptions filled at either plan retail pharmacies or our mail-order pharmacies. In some cases, prescriptions filled at a non-plan pharmacy may also be covered.

For certain prescription drugs, we have additional requirements for coverage or limits on our coverage. These requirements and limits are described in the Evidence of Coverage for each plan.

The formulary may change at any time. You will receive notice when necessary.
