Does HAP (Health Alliance Plan) Cover Delivery Pharmacy in Michigan?

‍

If you have HAP (Health Alliance Plan) in Michigan, prescription delivery is covered through your plan — and Wellscript Pharmacy accepts HAP plans across its commercial, Medicare Advantage, and dual-eligible product lines. Your medications can be delivered free to your door throughout metro Detroit.

HAP is one of Michigan's longest-standing health plans and a subsidiary of Henry Ford Health. Here's how your HAP prescription coverage works with a delivery pharmacy.

HAP in Michigan: Which Plans Are Available?

HAP is a Michigan-only health plan serving members across 50 Michigan counties. HAP offers several types of coverage:

HAP Commercial Plans — Employer-sponsored and individual/family health insurance plans available through employers and the Marketplace. Most HAP commercial plans include prescription drug coverage with tiered copays through HAP's formulary.

HAP Medicare Advantage (MAPD) Plans — Medicare Advantage plans combining Parts A, B, and D coverage. HAP offers HMO, HMO-POS, and PPO Medicare Advantage plans in Michigan with built-in prescription drug coverage.

HAP Medicare Complete Duals / HAP Medicare Complete Assist (D-SNP) — Dual Special Needs Plans for Michigan residents eligible for both Medicare and Medicaid. These plans coordinate both benefits and typically include very low or $0 cost-sharing for covered medications.

HAP CareSource MI Coordinated Health (HMO D-SNP) — Another D-SNP option through HAP's partnership with CareSource, serving dual-eligible Michigan members with integrated Medicare and Medicaid coverage. This plan partners with Express Scripts to manage pharmacy benefits.

HAP Federal Employee Plan (PSHB/FEHB) — HAP also serves federal employees and retirees in Michigan through the Postal Service Health Benefits program and the Federal Employees Health Benefits program.

HAP's Pharmacy Partner: Pharmacy Advantage

HAP's home delivery and specialty pharmacy services are provided through Pharmacy Advantage, HAP's contracted mail-order and specialty pharmacy partner. Pharmacy Advantage handles 90-day supply mail-order fills for maintenance medications — drugs you take regularly for chronic conditions like high blood pressure, diabetes, or high cholesterol.

HAP offers home delivery and specialty pharmacy services through Pharmacy Advantage, their contracted mail order provider, and members can get up to a 90-day supply of some medications.

Wellscript Pharmacy is a separate in-network delivery option — a local, licensed Michigan delivery pharmacy rather than a centralized mail-order facility. The practical difference is significant: Wellscript Pharmacy provides a local pharmacist who manages your complete medication profile, coordinates with your prescribers, handles prior authorizations, and delivers your medications to your door free of charge. Call us and we'll confirm your HAP plan coverage before you transfer.

Does HAP Cover Delivery Pharmacy?

Yes — HAP covers prescriptions filled at in-network pharmacies, including in-network delivery pharmacies. Most HAP plans include prescription drug coverage, and HAP offers a home-delivery pharmacy service to get drugs delivered right to your mailbox. Your standard copays apply based on your plan's tier structure, regardless of whether you pick up in person or receive delivery.

The key requirement is network participation. Prescriptions must be filled at a participating HAP pharmacy. Wellscript Pharmacy participates in major Michigan pharmacy networks. Call us at (248) 792-7059 and we'll verify your specific HAP plan before you transfer your prescriptions.

HAP's Tiered Formulary

HAP's commercial plans use a six-tier formulary structure:

• Tier 1 (Select Generic Drugs) — lowest cost-share; low-cost FDA-approved generics
• Tier 2 (Generic and Select Brand Drugs) — slightly higher cost-share; generic and select brand drugs meeting quality and cost-effectiveness guidelines
• Tier 3 (Preferred Brand) — preferred brand-name drugs
• Tier 4 (Non-Preferred Brand and Generic) — non-preferred drugs at higher cost-share
• Tier 5 (Preferred Specialty Drugs) — complex/chronic disease medications requiring prior authorization and specialty pharmacy dispensing
• Tier 6 (Non-Preferred Specialty Drugs) — non-preferred specialty medications requiring prior authorization

For HAP Medicare Advantage members, some highlights include $0 copays for Tier 1 drugs at a preferred pharmacy and a $0 copay for a 90-day supply of Tier 1 and Tier 2 drugs from Pharmacy Advantage or a preferred mail order pharmacy, even before meeting your deductible. Tier 1 and Tier 2 drugs include generics for blood pressure, cholesterol and diabetes.

HAP's 90-Day Prescription Program

HAP's 90-Day Prescription program allows coverage of up to a 90-day supply for medications on the HAP Maintenance Drug List at a participating retail pharmacy. Most major chains and many independent pharmacies are in the HAP 90-Day program. Typically the charge for a 90-day supply of medications on the Maintenance Drug List is two copays.

If your HAP plan supports 90-day fills at network pharmacies, Wellscript Pharmacy can fill your maintenance medications as a 90-day supply — delivered free to your door at the same two-copay cost.

Prior Authorizations Under HAP Plans

HAP requires prior authorization for specialty medications and certain other drugs on its formulary. Specialty drugs — used to treat complex conditions like rheumatoid arthritis, hepatitis C, HIV, and hemophilia — always require prior authorization and must be dispensed through Pharmacy Advantage or another designated specialty pharmacy.

For non-specialty medications that require PA, your doctor must submit the request. At Wellscript Pharmacy, we manage prior authorizations on your behalf for your non-specialty covered medications. When we receive a prescription that requires PA, we contact your prescriber, provide the documentation requirements, and follow up on the approval so you're not left waiting.

HAP Medicare 2026 Updates Worth Knowing

For HAP Medicare Advantage members, the annual out-of-pocket maximum for covered Part D drugs increased to $2,100 in 2026 (up from $2,000 in 2025), and the coverage gap phase was eliminated. This means once you reach $2,100 in out-of-pocket drug costs, your plan covers 100% of covered medications for the rest of the plan year.
