PrEP (pre-exposure prophylaxis) is available at little to no cost for most people in the U.S. through the Affordable Care Act, Medicare, and Medicaid. Uninsured individuals can access free medication via manufacturer assistance programs from Gilead and ViiV Healthcare or through specialized PrEP navigators and community clinics.
In Plain English: The Clinical Takeaway
- Insurance Coverage: Most ACA-compliant plans must cover PrEP medication, lab tests, and doctor visits at $0 out-of-pocket.
- Uninsured Options: Pharmaceutical companies (Gilead and ViiV) provide “Patient Assistance Programs” that give the drugs for free to those who qualify based on income.
- Navigation Help: “PrEP Navigators” are trained professionals who can help patients with insurance enrollment, financial co-pay assistance programs, and setting up needed medical appointments.

Navigating Insurance and Manufacturer Assistance
Under the Affordable Care Act (ACA), PrEP is classified as a preventive service. This means that for most marketplace plans, the medication, office visits, and the lab tests needed to maintain your prescription should be free. If you are using Medicare Part B or Medicaid, coverage is generally available, though you should verify specific coverage with your benefits counselor.

For those with commercial or private insurance who still face high deductibles, the Gilead Advancing Access Co-Pay Savings Program provides up to $8,000 annually for cost-sharing. Similarly, the ViiV Injectables Savings Program targets out-of-pocket costs for Apretude. It is vital to note that these programs are not available to those on government-funded plans like Medicare, Medicaid, or VA/TRICARE.
For the uninsured, the “Patient Assistance Program” (PAP) is the primary lifeline. These are programs that provide the medication at no cost to individuals who qualify. To find these resources, the PrEP Locator tool is an essential resource for identifying clinics that employ PrEP navigators—specialists who bridge the gap between a patient’s financial status and their clinical needs.
