Preventive Care Services Covered Fully Under Health Insurance

Preventive care covered by health insurance can save you hundreds of dollars a year. Most private health plans in the United States must cover a long list of preventive services at no cost to you: no copay, no coinsurance, and no deductible, as long as you use an in-network provider. That one rule, written into the Affordable Care Act (ACA), means a flu shot, a blood pressure check, a colonoscopy at the recommended age, or a child’s well visit can cost you exactly nothing at the point of care.
Yet many people never use these benefits, and others get surprise bills for care they thought was free. The gap usually comes down to fine print: which services qualify, who is eligible, how the visit is coded, and whether the provider is in your network.
This guide explains what preventive care is fully covered, where the rules come from, the traps that turn a free visit into a bill, the latest legal changes, and exactly what to do if you are charged when you should not be.
The Law Behind It: ACA Section 2713
Section 2713 of the Public Health Service Act, added by the ACA, requires most private plans to cover recommended preventive services with zero cost-sharing. Federal estimates put the number of people in plans subject to this rule at roughly 150 to 180 million (Congressional Research Service).
The law does not list the services itself. Instead, it points to four expert sources, and anything they recommend becomes a covered benefit:

What it decides
Examples
U.S. Preventive Services Task Force (USPSTF)
Screenings, counseling and preventive drugs graded “A” or “B”
Colorectal and breast cancer screening, statins, PrEP for HIV
CDC’s Advisory Committee on Immunization Practices (ACIP)
Vaccines on the CDC immunization schedules
Flu, Tdap, HPV, shingles, pneumococcal
HRSA Bright Futures guidelines
Preventive care for infants, children and teens
Well-child visits, developmental and vision screening
HRSA Women’s Preventive Services Guidelines
Preventive care for women
Well-woman visits, contraception, breastfeeding support
When a recommendation is added or changed, plans generally must cover it starting with the plan year that begins one year after the change. So a brand-new screening may not be free on your plan immediately.
Who is covered: individual Marketplace plans, most employer plans (fully insured and self-funded), and Medicaid expansion coverage. Who is not: grandfathered plans that existed before March 23, 2010 and have not changed significantly, short-term health plans, and health care sharing ministries. Medicare has its own preventive benefit with similar but separate rules.
Preventive Services Covered for All Adults
Adults are entitled to dozens of no-cost services, though most depend on your age, sex or risk factors. The core ones include:
• Cancer screenings: colorectal cancer screening for adults 45 to 75 (including a follow-up colonoscopy after a positive stool test), lung cancer screening with low-dose CT for certain adults 50 to 80 with a heavy smoking history, and cervical and breast cancer screening (covered under the women’s section below).
• Heart and metabolic health: blood pressure screening, cholesterol checks, statins for adults 40 to 75 at elevated cardiovascular risk, and screening for prediabetes and type 2 diabetes in adults 35 to 70 who are overweight or obese.
• Infectious disease: HIV screening for ages 15 to 65, hepatitis B and C screening, syphilis and other STI screening for those at increased risk, and PrEP medication for people at high risk of HIV.
• Behavioral health: depression screening, anxiety screening, unhealthy alcohol use screening and counseling, and tobacco use counseling plus FDA-approved cessation medications.
• Weight and lifestyle: obesity screening and intensive behavioral counseling, and diet counseling for adults at higher risk of chronic disease.
• Other screenings: abdominal aortic aneurysm screening (one time) for men 65 to 75 who have ever smoked, osteoporosis screening for women 65 and older, and fall-prevention exercise for adults 65 and older.
• Vaccines: flu, COVID-19, Tdap and Td boosters, shingles (50 and older), pneumococcal, hepatitis A and B, HPV (through age 26, and some older adults), RSV for older adults, measles-mumps-rubella, chickenpox and meningococcal, depending on age and risk.
An annual wellness or preventive visit is typically the doorway to many of these, and the visit itself is covered when its purpose is prevention.
Preventive Services for Women and Pregnancy
Women receive additional no-cost coverage through the HRSA Women’s Preventive Services Guidelines, on top of everything adults receive.
• Well-woman visits: at least one per year, and more if needed to deliver all recommended services.
• Breast cancer: screening mammograms every two years starting at 40 (per the current USPSTF recommendation), plus genetic counseling and BRCA testing for women with a qualifying family history, and risk-reducing medication for those at high risk.
• Cervical cancer: Pap tests and HPV testing on the recommended schedule.
• Contraception: FDA-approved birth control methods, including counseling, insertion and removal, without cost-sharing. Plans may use “reasonable medical management,” such as covering a generic version at $0, but must offer an exceptions process. Some religious employers are exempt.
• Pregnancy: screening for gestational diabetes, preeclampsia, hepatitis B, syphilis, HIV, Rh incompatibility and urinary tract infection; folic acid supplements; low-dose aspirin for those at high risk of preeclampsia; and perinatal depression counseling.
• Breastfeeding: lactation counseling and the cost of a breast pump, rental or purchase depending on the plan.
• Other: intimate partner violence screening, urinary incontinence screening, and osteoporosis screening.
Note that routine prenatal visits themselves are often billed as a bundled maternity package, which may carry cost-sharing even though the individual screenings inside it are preventive.
Preventive Services for Children and Adolescents
Children have the broadest preventive benefit of any group, built mostly on the Bright Futures schedule from the American Academy of Pediatrics and HRSA.
• Well-child visits: frequent visits in the first years of life (newborn, then roughly 1, 2, 4, 6, 9, 12, 15, 18, 24 and 30 months), then annually from age 3 through 21.
• Newborn screening: hearing, congenital heart defects (pulse oximetry), metabolic and genetic disorders, and preventive eye medication.
• Growth and development: height, weight and BMI tracking, developmental screening, and autism screening at 18 and 24 months.
• Vision, hearing and oral health: vision screening, hearing checks, fluoride varnish for young children and fluoride supplements where water is not fluoridated.
• Blood and lead tests: anemia, lead screening for at-risk children, and cholesterol screening at set ages.
• Adolescent care: depression and suicide-risk screening from age 12, alcohol and drug use assessment, STI and HIV screening, and contraception counseling.
• Vaccines: all vaccines on the CDC childhood and adolescent schedules.
On vaccines, there is one recent change parents should know: in January 2026 the CDC narrowed the number of vaccines it universally recommends for healthy children from 17 to 11, moving others to high-risk or “shared clinical decision-making” categories. However, federal officials stated that every vaccine recommended as of December 31, 2025, including those moved to shared decision-making, remains covered without cost-sharing by ACA plans, Medicaid, CHIP and the Vaccines for Children program (AMCP; WebMD). In practice, your child can still get the full set at no charge.
The Fine Print: Why “Free” Care Sometimes Comes With a Bill
Most surprise charges for preventive care trace back to one of five issues.
1. Out-of-network providers. The $0 rule applies only in-network. If you see an out-of-network doctor, your plan can charge normal cost-sharing. The exception: if your network has no provider who offers the service, the plan must cover it out-of-network at $0.
2. Preventive versus diagnostic. A screening is preventive when you have no symptoms. Once you raise a new problem, such as chest pain or a lump, the visit becomes diagnostic and normal cost-sharing applies. A single visit can be split: the physical is free, while the separate discussion of your knee pain is billed as an office visit.
3. Primary purpose of the visit. If a preventive service is delivered during a visit whose main purpose is something else, the plan may charge for the visit itself even though the screening is free.
4. Labs and add-ons. Not every blood test ordered at a physical is on the recommended list. A cholesterol panel may be free, while a vitamin D or thyroid test might not be. Ask what is being ordered and why.
5. Frequency and age limits. Coverage follows the recommendation. A mammogram every year instead of every two, or a colonoscopy at 40 with no risk factors, may not qualify. Plans may set reasonable limits on frequency, method and setting where the guideline is silent.
One more point: plans must also cover anesthesia, bowel prep and pathology tied to a screening colonoscopy, and the follow-up colonoscopy after a positive stool-based test, at no cost.
Recent Legal and Policy Changes
The $0 preventive care guarantee survived its biggest legal threat in 2025, but who sets the recommendations is now a live political question.
Date
Event
What it means for you
Jan 5, 2026
CDC revised the childhood immunization schedule, moving six vaccines out of the universal category
All vaccines recommended as of Dec 31, 2025 stay covered at $0
Jun 27, 2025
Supreme Court decided Kennedy v. Braidwood Management (6-3)
USPSTF-based coverage is constitutional; screenings, statins and PrEP stay free
Mar 30, 2023
Texas federal court struck down USPSTF-based coverage nationwide
Later narrowed on appeal and reversed by the Supreme Court; insurers largely kept coverage in place
In Braidwood, the Court held that Task Force members are properly appointed because the HHS Secretary can appoint and remove them (KFF; Health Affairs). That settles the legal question but also confirms the Secretary’s power over what the Task Force recommends, and litigation over the HRSA and ACIP pieces may continue in lower courts.
The practical takeaway: coverage today is intact, but recommendations can change, and any change normally reaches your plan the following plan year. Check your plan’s preventive care list each year at open enrollment.
How to Get the Most From Your Benefit
A few habits will keep preventive care free in practice, not just on paper.
1. Confirm the network. Check that the clinic, the doctor and the lab are all in-network. A free visit can still produce a lab bill if your sample goes to an out-of-network lab.
2. Book it as preventive. When scheduling, say “annual preventive visit” or “screening colonoscopy,” not “checkup for my back.”
3. Separate new problems. If you want to discuss a new symptom, ask whether it will be billed separately, or book a second appointment.
4. Ask about each test. Before blood is drawn, ask which tests are preventive and which may cost you.
5. Use your plan’s list. Most insurers publish a preventive care guide listing covered services and billing codes. HealthCare.gov also keeps official lists for adults, women and children.
If You Get a Bill
1. Read the Explanation of Benefits (EOB). Look for the service and whether it was processed as preventive.
2. Call the provider’s billing office. Many errors are coding mistakes; ask whether a preventive code (and modifier 33, which flags a service as preventive) was used.
3. Call your insurer. Ask them to reprocess the claim as preventive, citing ACA Section 2713 and the specific recommendation.
4. File an appeal. If denied, you have the right to an internal appeal and then an external review by an independent reviewer.
5. Get outside help. Your state insurance department, or the U.S. Department of Labor for employer self-funded plans, can step in.
Frequently Asked Questions
Do I have to meet my deductible first? No. Covered preventive services must be paid in full before any deductible, including on high-deductible health plans paired with an HSA.
Is my annual physical always free? The preventive portion is. Anything addressing an existing condition or new symptom can be billed separately.
Are preventive prescriptions free? Some are: statins for eligible adults, PrEP, tobacco cessation drugs, contraceptives, folic acid in pregnancy and low-dose aspirin for preeclampsia risk, among others. Your plan may limit $0 coverage to generic versions.
Does Medicare work the same way? Medicare Part B covers a similar list of preventive services at no cost when your provider accepts assignment, under its own separate rules.
How do I know if my plan is grandfathered? Your plan documents must say so. Few grandfathered plans remain today.
Conclusion
Preventive care covered by health insurance is one of the most valuable benefits in any health plan, and it is guaranteed by law for most insured Americans. Cancer screenings, vaccines, well-child visits, contraception and dozens of other services should cost you nothing when you stay in-network and the visit is coded as preventive. The 2025 Supreme Court ruling secured the core of this protection, and federal officials have kept vaccine coverage intact despite schedule changes. Know what you are entitled to, ask questions before tests are run, and challenge any bill that looks wrong.
