For most people with private insurance, PrEP costs $0 out of pocket. Federal law requires non-grandfathered health plans to cover all three FDA-approved PrEP medications, along with related lab work and clinic visits, without any copay, coinsurance, or deductible. This applies whether you get PrEP through a traditional doctor’s office, a sexual health clinic, or an online provider.
That said, the reality of insurance billing doesn’t always match the law on paper. Some people still encounter unexpected charges depending on how their plan processes claims, which PrEP formulation they use, or where they get their injections. Here’s what to expect and how to navigate it.
Why PrEP Is Legally Free With Insurance
The Affordable Care Act requires private health plans to cover preventive services that receive an “A” or “B” rating from the U.S. Preventive Services Task Force (USPSTF) with zero cost sharing. PrEP has held a Grade A recommendation since 2019, and the USPSTF updated that recommendation in August 2023 to explicitly include all three FDA-approved formulations: daily oral tenofovir/emtricitabine (generic Truvada), daily oral Descovy, and the injectable Apretude.
As of plan years beginning on or after August 31, 2024, insurers must cover all three formulations without directing you toward one over another. That means your plan cannot require you to try generic tenofovir/emtricitabine before approving Descovy or Apretude, and it cannot charge you more for the brand-name options. The zero-cost requirement also applies before you’ve met your annual deductible, including on high-deductible health plans paired with a health savings account.
This mandate was briefly threatened by a federal lawsuit (Braidwood v. Becerra) that challenged the ACA’s preventive care requirements. The Supreme Court upheld those requirements in a July 2025 decision, so the zero-cost mandate remains in effect nationwide.
What’s Covered Beyond the Medication
The federal coverage requirement isn’t limited to the pills or injections themselves. Your plan must also cover the clinical services needed to start and stay on PrEP without charging you. These include the initial HIV test before starting PrEP, up to eight HIV screening tests per year while you’re on it, a one-time hepatitis B screening, kidney function monitoring for oral PrEP, STI screenings recommended by your provider, and the office visits tied to these services.
For injectable PrEP specifically, your plan must cover the cost of the injection administration, not just the drug. Medicare Part B, which began covering PrEP as of October 2024, similarly covers both the medication and injection fees.
When You Might Still See a Bill
Despite the legal requirement, billing errors and plan misclassifications happen. The most common scenarios where insured patients encounter charges include visits coded as diagnostic rather than preventive (for instance, if your provider bills for a general office visit instead of a PrEP-specific preventive visit), out-of-network lab work, or claims processed under the wrong benefit category. Injectable PrEP can be especially tricky because some plans process it under the medical benefit while others use the pharmacy benefit, and miscategorization can trigger unexpected cost sharing.
If you receive a bill, it’s worth calling your insurer and asking them to reprocess the claim as a preventive service. Reference the USPSTF Grade A recommendation for PrEP. In many cases, these charges result from coding errors rather than intentional coverage denials.
Grandfathered health plans, meaning plans that existed before the ACA took effect in 2010 and haven’t made significant changes since, are exempt from the preventive services mandate. If you’re on one of these increasingly rare plans, you could face standard copays or coinsurance. Your plan documents or your HR department can tell you whether your plan is grandfathered.
Manufacturer Savings Programs
Even when insurance should cover everything, manufacturer assistance programs exist as a backup. Gilead, which makes both generic tenofovir/emtricitabine and Descovy, offers a copay card through its Advancing Access program that covers up to $7,200 per year in out-of-pocket costs. There are no income restrictions, and it’s available to anyone with private insurance, including marketplace and employer-sponsored plans. People on Medicare, Medicaid, or other government programs are not eligible.
ViiV Healthcare offers a similar program for Apretude through ViiVConnect, covering up to $7,500 per year toward deductibles, medication copays, and injection administration copays. Eligible patients can pay as little as $0. One limitation: the ViiV program does not cover costs for clinical testing or office visits, so those would need to go through your insurance separately.
These programs are worth enrolling in even if your insurance is covering PrEP fully. They act as a safety net if your plan processes a claim incorrectly or if you switch insurance mid-year.
State PrEP Assistance Programs
Most states run PrEP Drug Assistance Programs (PrEP-DAPs) that can fill gaps your insurance doesn’t cover. These programs typically pay the patient portion of deductibles, copays, and coinsurance for people who qualify based on income or residency. Washington State’s program, for example, covers those costs up to a set maximum for enrollees who already have insurance.
PrEP-DAPs vary significantly by state in terms of eligibility, covered services, and application processes. Your local health department or an HIV prevention organization can help you find and apply for your state’s program. These programs can be especially useful if you’re on a grandfathered plan or if your insurer is slow to comply with updated coverage rules.
Online PrEP Providers and Insurance
Telehealth platforms have made starting PrEP more convenient, but their relationship with insurance varies. Nurx bills insurance directly, though it charges a $15 consultation fee and a $35 fee for its at-home PrEP lab kit that you may need to reconcile with your insurer. PlushCare charges a $99 physician consultation fee and requires you to handle lab payments separately.
Mistr takes a different approach entirely: it doesn’t bill insurance at all. Instead, it charges $99 per quarter, which includes labs and consultations. In nine states (California, Florida, Indiana, Oregon, Alabama, Mississippi, Georgia, South Carolina, and Texas), that fee is waived through nonprofit partnerships, making the service completely free.
If you’re using an online provider and have insurance, confirm upfront whether they’ll bill your plan for the preventive services or whether you’ll need to submit claims yourself. The zero-cost mandate applies regardless of where you receive care, but getting your insurer to process a telehealth claim correctly sometimes requires a follow-up call.
Medicare and Medicaid Coverage
Medicare Part B began covering PrEP medication and related services, including injection fees for Apretude, as of October 2024. Medicaid expansion programs are also required to cover PrEP without cost sharing under the ACA’s preventive services rules. If you’re on Medicaid in a non-expansion state, coverage varies, but most state Medicaid programs do cover PrEP in some form.
One important distinction for government plan enrollees: you are not eligible for manufacturer copay cards from Gilead or ViiV. However, your cost sharing through Medicare or Medicaid is typically minimal or zero anyway, and state PrEP-DAP programs can often cover any remaining patient costs.
