Protect your health

HAP offers resources to help you protect your health.

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.

Health Alliance Plan (HAP) has HMO, HMO-POS, PPO plans with Medicare contracts. HAP Medicare Complete Duals (HMO D-SNP) and HAP Medicare Complete Assist (PPO D-SNP) are Medicare health plans with Medicare contracts and a contract with the Michigan Medicaid Program. Enrollment depends on contract renewals.
