It depends on your health plan. For millions of Americans, the answer is more complicated than a simple yes or no. Under the Affordable Care Act (ACA), most private health insurance plans must cover a set of preventive services without charging you a copayment, coinsurance, or deductible when those services are delivered by an in-network provider. Nuances around grandfathering, plan type, and what actually qualifies as preventive mean every employee and employer should understand the details.
What the ACA Requires for Preventive Care
The ACA mandates that non-grandfathered group health plans and health insurance issuers cover a defined list of preventive services at no cost to the patient. These include:
- Screenings for conditions like high blood pressure, diabetes, and certain cancers (e.g., mammograms, colonoscopies)
- Immunizations such as flu shots and HPV vaccines
- Counseling for issues like smoking cessation, obesity, and depression
- Well-woman visits and well-child visits
- Contraceptives and contraceptive counseling (with some religious exemptions)
These services are covered with zero cost-sharing when you see an in-network provider. But the catch: coverage applies only to the specific, recommended services on the U.S. Preventive Services Task Force (USPSTF) A and B ratings list, along with immunizations recommended by the Advisory Committee on Immunization Practices (ACIP) and HRSA-supported guidelines for women, children, and infants.
The Supreme Court Upheld the Preventive Mandate
Between 2023 and 2025, this requirement faced its most serious legal test. In Braidwood Management v. Becerra, Texas employers and individuals argued that the U.S. Preventive Services Task Force is unconstitutional because its volunteer members are not appointed by the President and confirmed by the Senate. A federal district court agreed in March 2023 and blocked the requirement nationwide; the Fifth Circuit narrowed that relief to the plaintiffs in June 2024.
On June 27, 2025, the Supreme Court resolved the core question in Kennedy v. Braidwood, a 6-3 decision. The Court held that Task Force members are inferior officers who are properly appointed, and who are supervised and directed by the Secretary of Health and Human Services. The mandate stands: private plans must still cover USPSTF A and B services, ACIP-recommended immunizations, and HRSA-supported services for women, children, and infants without cost sharing. The provision reaches more than 150 million people a year.
The case is not fully closed. The Court did not rule on the plaintiffs' challenge to the Advisory Committee on Immunization Practices, and lower courts continue to weigh ratification of HRSA guidelines and religious objections to PrEP and contraceptive coverage. For now, the core no-cost preventive coverage remains in effect.
When Preventive Care Still Costs You Money
Despite the ACA's requirements, several scenarios can still leave you with out-of-pocket costs for preventive services:
1. Grandfathered Plans
If your employer's plan has been around since before March 23, 2010, and hasn't seen major changes, it might be grandfathered. That means it's exempt from the preventive care mandate. Employers must disclose grandfathered status in plan materials.
2. Out-of-Network Providers
The ACA only mandates no-cost coverage for preventive services from in-network providers. Go out-of-network, and you could face a bill.
3. Diagnostic vs. Preventive Confusion
This is the most common surprise: if a doctor finds a problem during a preventive visit and performs additional tests (like a biopsy during a colonoscopy), those services are considered diagnostic, not preventive. That means you can be charged. Always ask ahead: "Will anything done today be billed as diagnostic?"
4. Plan Design Variations
Even within ACA-compliant plans, employers can structure benefits to limit no-cost coverage. Stand-alone dental plans for adults, for instance, aren't required to cover preventive dental at $0. Some high-deductible health plans (HDHPs) can cover preventive care before the deductible without losing HSA eligibility, but the services must fall within the plan's preventive-care definition.
The WellthCare Approach: A Different Model for Preventive Care
Traditional health insurance, even with ACA preventive mandates, still leaves gaps. Employees delay care due to confusion, and employers see higher claims downstream. WellthCare, the first Health-to-Wealth Benefit System, closes the gap by rewarding preventive actions with earned reward dollars and retirement savings, lowering employer claims in the process. Enter WellthCare, a system that works alongside your existing plan rather than replacing it.
WellthCare covers preventive services and rewards employees for taking those actions. Employees earn reward dollars at the WellthCare Store, and program savings fund automatic retirement contributions. Both balances compound over time. This approach:
- Eliminates deductibles for preventive care through a $0-co-pay model
- Rewards preventive behavior so it becomes visible and valued
- Reduces waste by catching issues early, before claims escalate
ACA mandates a floor; WellthCare turns prevention into a driver of financial security for employees and lower costs for employers.
What Employers Should Verify for Compliance
If you're an employer offering group health coverage, ensure your plan documents clearly define what preventive services are covered at $0 cost-sharing. Key compliance steps include:
- Check if your plan is not grandfathered, and if it is, disclose that.
- Audit your Summary of Benefits and Coverage (SBC) to confirm preventive services are listed correctly.
- Make sure your network of providers understands the preventive vs. diagnostic billing distinction.
- Communicate clearly to employees: what's free, and how to get it in-network.
- Consider modernizing benefits with systems like WellthCare that align prevention with wealth-building.
Failure to comply with ACA preventive service mandates can trigger excise taxes under Internal Revenue Code Section 4980D, generally $100 per day per affected individual, plus unhappy employees. But getting prevention right is the best way to reduce long-term healthcare costs.
Final Takeaway
Yes, most health plans must cover a defined set of preventive services with no out-of-pocket costs, but real-world experience is messier. Grandfathering, diagnostic billing, and provider confusion all get in the way. To unlock prevention, forward-thinking employers are moving beyond compliance into systems like WellthCare, where every preventive action builds the employee's wealth too. Healthcare that pays you back. That's the future.
