TL;DR
Under the ACA, most insurance plans must cover PrEP at $0 — medication, office visits, and labs included. This has been federal requirement since 2020. If your insurance is charging you a copay for PrEP, file an internal appeal citing the ACA preventive services mandate. Appeals succeed most of the time. If your plan is grandfathered, a short-term plan, or you're on Medicare (not subject to this mandate), use manufacturer copay cards (Gilead: up to $7,200/year; ViiV: up to $7,500/year) or switch to a telehealth platform offering $0 PrEP regardless of insurance.
The rule: "no cost-sharing" for PrEP
In June 2019, the U.S. Preventive Services Task Force gave PrEP a grade "A" recommendation. Under the Affordable Care Act, any preventive service with a USPSTF grade "A" or "B" recommendation must be covered by most commercial insurance plans without cost-sharing. That means no copay, no coinsurance, and no deductible.
In July 2021, HHS issued clarifying guidance making clear that the coverage applies to the entire PrEP care bundle — not just the medication:
- The PrEP medication itself (Truvada, generic TDF/FTC, Descovy, Apretude, and Yeztugo)
- Office visits and consultations for PrEP
- Required lab work (HIV tests, kidney function, hepatitis B/C, STI screening)
- Injection administration for injectable PrEP
In short: if your insurance plan is subject to the ACA preventive services mandate, your out-of-pocket cost for routine PrEP care should be exactly $0.
Which plans must cover PrEP at $0
Most commercial plans are subject to the mandate. Specifically:
Subject to the $0 mandate
Commercial ACA marketplace plans (Healthcare.gov and state exchanges); most employer-sponsored plans; small group plans; individual plans purchased off-exchange that aren't grandfathered. These account for the majority of insured Americans.
Already at $0 through other mechanisms
Medicaid (all 50 states cover PrEP at $0 under a combination of ACA expansion requirements and state-level preventive services rules); Medicare Part B (covers Apretude and Yeztugo as Part B services with 80/20 cost-sharing, or $0 with Medigap or LIS).
Not subject to the mandate
Grandfathered plans (plans that existed before March 23, 2010 and haven't been significantly modified — shrinking share of the market); short-term limited-duration insurance plans; health care sharing ministries (not technically insurance); self-funded plans claiming a religious exemption; Medicare Part D for oral PrEP. For these plans, manufacturer copay cards and patient assistance programs are the primary fallbacks.
Common reasons your insurance is charging a copay anyway
Even though the rule is clear, insurance plans still regularly misapply it. Here are the most common reasons insured patients get charged for PrEP — and what's actually going on.
1. The pharmacy isn't billing it as preventive
Sometimes the pharmacy submits your PrEP prescription without the preventive services modifier. The insurance system then processes it like any other prescription, applying your regular formulary tier and copay. Fix: Ask the pharmacist to re-submit with the preventive services coding (ICD-10 code Z20.6 for HIV exposure; HCPCS code for PrEP bundle).
2. The insurance requires prior authorization
Some plans require prior authorization before covering certain PrEP medications (especially Descovy, Apretude, and Yeztugo since they're more expensive than generic alternatives). If prior auth hasn't been filed or has been denied, you'll be charged full cost. Fix: Ask your prescriber to submit the prior authorization with clinical justification.
3. Your plan puts brand PrEP on a higher tier
Many plans cover generic TDF/FTC at $0 but apply a copay to brand Descovy on the theory that generics are therapeutically equivalent. Under the ACA, plans can still require patients to try generics first (step therapy), but they must provide exception processes when generics aren't appropriate. Fix: Either switch to generic TDF/FTC, or have your prescriber submit a medical necessity letter for Descovy.
4. Your plan is grandfathered or self-funded
Grandfathered plans and certain self-funded plans aren't subject to the ACA preventive services mandate. If you're on one of these plans, your insurance doesn't have to cover PrEP at $0. Fix: Check with your HR department whether your plan is grandfathered. If it is, use a manufacturer copay card or a telehealth $0 option.
5. The deductible is applied incorrectly
Some plans wrongly apply PrEP costs to your medical deductible. Under the ACA, preventive services are covered before the deductible, not after. Fix: File an appeal pointing out that PrEP is a preventive service not subject to the deductible.

How to appeal a PrEP copay (step-by-step)
Step 1: Call your insurance
Call the member services number on your insurance card. Ask: "Under the ACA preventive services mandate and USPSTF's Grade A recommendation for PrEP, is this plan supposed to cover PrEP without cost-sharing? Why am I being charged a copay?" Specifically reference USPSTF Grade A recommendation (2019) and the HHS July 2021 guidance. Document the name of the representative and the conversation details.
Step 2: Submit a formal written appeal
If the call doesn't resolve it, file a formal written appeal. Every insurance plan must have an appeals process. Request information on how to file the appeal in writing.
Your appeal should include:
- Your name, policy number, and claim or prescription reference
- Citation of the USPSTF Grade A recommendation for PrEP (June 2019)
- Citation of the July 2021 HHS guidance on PrEP preventive services coverage
- Your prescribing physician's documentation that PrEP is medically indicated
- Request that the copay be reversed and reprocessed as a covered preventive service
Step 3: If the internal appeal fails, file an external review
If your insurance denies the internal appeal, you have the right to an external review by an independent third party. External reviews for ACA preventive services issues have a strong track record of ruling in favor of patients. Contact your state insurance regulator or file through HealthCare.gov for federal marketplace plans.
Step 4: File a complaint with your state insurance commissioner
As a final step, complaints to state insurance commissioners or the federal Center for Consumer Information and Insurance Oversight (CCIIO) frequently get results, even when internal appeals don't. Insurance companies pay attention to regulatory complaints.
Manufacturer copay cards (if your plan legitimately charges a copay)
For commercially insured patients whose plans legally charge a PrEP copay — either because the plan is grandfathered or because the insurance is misapplying the rule and the appeal process is taking time — manufacturer copay savings programs can cover the gap.
| Copay program | Drug covered | Annual maximum | Income limit? |
|---|---|---|---|
| Gilead Copay Savings Program | Descovy | $7,200/year | None |
| Gilead Yeztugo Copay Savings | Yeztugo | $8,000/year + $100/visit | None |
| APRETUDE Savings Program | Apretude | ~$7,500/year | None |
These programs are only available to commercially insured patients. Medicare, Medicaid, Tricare, and VA beneficiaries are excluded by federal law. For generic TDF/FTC, no manufacturer copay card exists. If your insurance is charging you for generic PrEP, your options are (a) appeal it to $0 under the ACA mandate, or (b) switch to a telehealth platform with $0 generic PrEP.
The fallback: skip the copay fight entirely
If you don't want to spend weeks navigating an insurance appeal, or if your plan isn't subject to the ACA mandate, online telehealth platforms partnered with 340B-covered entities provide $0 PrEP regardless of your insurance situation. For many patients, this is faster and less frustrating than fighting an insurance plan that's wrongly charging a copay.

Frequently asked questions
Is PrEP supposed to be free with insurance?
Under the ACA preventive services mandate, most commercial insurance plans (and all Medicaid programs) must cover PrEP medication, office visits, and lab work without cost-sharing — meaning $0 copay. This has been the rule since 2020. Exceptions include grandfathered plans, short-term plans, and certain self-funded plans claiming religious exemptions.
What should I do if my insurance is charging me a copay for PrEP?
First, call your insurance and ask specifically whether the plan is subject to the ACA preventive services mandate for PrEP. Cite the USPSTF Grade A recommendation and the July 2021 HHS guidance. If that doesn't resolve it, file a formal written appeal. Internal appeals frequently succeed. If the internal appeal fails, file an external review and/or a complaint with your state insurance commissioner.
Does the no-copay rule apply to Descovy and Apretude too?
Yes — the ACA preventive services mandate applies to PrEP as a preventive intervention, not to specific drugs. All FDA-approved PrEP medications are covered under the mandate. However, insurance plans are allowed to require step therapy (trying generic first) and prior authorization, as long as they provide exception processes when generics aren't clinically appropriate.
What if my plan is grandfathered?
Grandfathered plans are plans that existed before March 23, 2010 and haven't been significantly modified. They aren't subject to the ACA preventive services mandate. A dwindling number of Americans are on grandfathered plans (less than 10% as of 2026). If you're on one, use a manufacturer copay card (up to $7,200/year for Descovy), switch to generic TDF/FTC (~$30/month cash), or use a $0 telehealth platform.
Does Medicare cover PrEP without a copay?
Medicare Part B now covers injectable PrEP (Apretude, Yeztugo) as a preventive service, though standard 80/20 cost-sharing applies unless you have Medigap or LIS. Medicare Part D covers oral PrEP with standard Part D cost-sharing (often including a copay). Medicare isn't subject to the ACA preventive services mandate the same way commercial insurance is — the Medicare coverage framework is different.
Can I get generic PrEP at $0?
Yes. Medicaid covers generic TDF/FTC at $0 in all 50 states. Commercial insurance must cover generic TDF/FTC at $0 under the ACA preventive services mandate. Uninsured patients can get generic TDF/FTC at $0 through many telehealth platforms that partner with 340B-covered entities, though no manufacturer patient assistance program exists for generic PrEP.
How long does a PrEP copay appeal take?
Internal appeals are typically decided within 30–60 days. External reviews (if the internal appeal fails) typically take another 30–45 days. In urgent situations, expedited appeals can be decided in 72 hours. If you don't want to wait, a telehealth platform offering $0 PrEP can usually have you on medication within a week.
