Most health plans must cover a long list of screenings, vaccines and counseling visits with no copay, no coinsurance and no deductible, as long as you use an in-network provider. That is the heart of free preventive care under the ACA. The rule applies to nearly all employer plans and Marketplace plans, and it is meant to catch problems early, when they are cheaper and easier to manage. The catch is that “free” depends on the exact service, your age, your risk factors and how the visit is billed.
Key Takeaways
- Non-grandfathered private plans must cover recommended preventive services without cost sharing when you see an in-network provider.
- Coverage is tied to three official sources: the U.S. Preventive Services Task Force (grades A and B), the CDC’s vaccine advisory committee, and federal women’s and children’s health guidelines.
- A service billed as “diagnostic” because you have symptoms can still carry a charge, even if the same test would be free as a screening.
- Your plan may use reasonable limits on frequency, age and setting, so check before you schedule.
- If you are unsure, ask the provider’s billing office to confirm the billing code before the appointment.
Where Free Preventive Care Under the ACA Comes From
Section 2713 of the Affordable Care Act requires most plans to cover three categories of services at no cost to you:
- Task Force recommendations rated A or B. The U.S. Preventive Services Task Force reviews research on screenings, medications and counseling. An “A” or “B” grade means there is solid evidence of a net benefit.
- Immunizations. Vaccines recommended by the CDC’s Advisory Committee on Immunization Practices and adopted by the CDC.
- Federal guidelines for women, infants, children and adolescents. These come from the Health Resources and Services Administration and cover things like well-woman visits and well-child checkups.
In June 2025, the U.S. Supreme Court upheld the structure of the Task Force in a case called Kennedy v. Braidwood Management, which kept the preventive coverage requirement in place. Because the list of recommendations is updated over time, always confirm current details on Healthcare.gov or with your plan.
Preventive Services for Adults, Organized by Age Range
The Task Force recommendations are specific about who should be screened and how often. The table below summarizes common examples. These are general descriptions, and your doctor may adjust them based on your history.
| Service | Typical group it applies to | Typical frequency |
|---|---|---|
| Blood pressure screening | Adults 18 and older | At routine visits; yearly for older adults or higher risk |
| Colorectal cancer screening | Ages 45 to 75 | Depends on test type, such as colonoscopy every 10 years or stool tests more often |
| Breast cancer screening (mammogram) | Women 40 to 74 | Every two years |
| Cervical cancer screening | Women 21 to 65 | Every 3 to 5 years depending on age and test |
| Lung cancer screening (low-dose CT) | Ages 50 to 80 with a heavy smoking history who smoke or quit within 15 years | Yearly |
| Type 2 diabetes screening | Ages 35 to 70 with overweight or obesity | Roughly every 3 years if results are normal |
| Hepatitis C screening | Adults 18 to 79 | At least once |
| HIV screening | Ages 15 to 65, and others at higher risk | At least once, more often with risk |
| Depression and anxiety screening | Adults (anxiety screening for adults up to age 64) | At routine visits as recommended |
| Statin medication for heart disease prevention | Ages 40 to 75 with risk factors and elevated 10-year risk | Ongoing, with a prescription |
Other covered items often include flu shots, tetanus boosters, shingles vaccines for qualifying ages, tobacco cessation counseling and medications, and counseling for healthy diet and physical activity for adults at higher risk of heart disease. Healthcare.gov publishes a preventive care benefits list organized by adults, women and children.
Preventive Services for Women and Pregnancy
Women’s preventive guidelines add several services that often surprise people. Depending on the plan and the recommendation, covered services can include:
- A yearly well-woman visit.
- Screening for gestational diabetes during pregnancy.
- Breastfeeding support, counseling and, for many plans, equipment such as breast pumps.
- Contraceptive methods and counseling approved by the FDA, with some plan or employer exceptions.
- Screening and counseling for interpersonal violence.
- Folic acid supplements for people planning pregnancy, where prescribed.
Lab work ordered because of symptoms, such as testing for the causes of fatigue described in iron deficiency symptoms in women, is usually billed as diagnostic rather than preventive, so it follows your normal deductible and coinsurance.
Children and Teens
For kids, the guidelines come from a schedule of well-child visits, immunizations, developmental screening, vision and hearing screening, and counseling. Covered items include:
- Regular well-child visits from birth through adolescence.
- Childhood immunizations such as MMR, polio and whooping cough vaccines.
- Developmental and autism screening at specific ages.
- Lead and anemia screening when risk is present.
- Behavioral and depression screening for teens.
- Fluoride varnish for young children and fluoride supplements where water is low in fluoride.
Dental checkups themselves are not part of the medical preventive package for adults, which is why many people look into dental insurance vs dental savings plans.
When Free Preventive Care Isn’t Free
This is where most surprise bills come from. Understanding these situations can save you money.
Screening versus diagnostic
A screening is done when you have no symptoms. A diagnostic test is done to investigate a symptom or follow up on an abnormal result. If you go in for a mammogram because you found a lump, it may be billed as diagnostic and subject to your deductible. The same test, done as a routine screening, is typically free.
Colonoscopy details
Federal guidance says that a colonoscopy after an abnormal stool-based test should be treated as part of the screening, with no cost sharing. Removal of a polyp during a screening colonoscopy is also generally treated as part of the preventive service. Some anesthesia charges and facility fees are less consistently handled, so confirm with the plan.
Out-of-network providers
The no-cost rule applies to in-network care. An out-of-network provider can bill you for the visit, and the plan may pay only part of it, or nothing. Confirm the network status of the doctor, the lab and the facility separately, because they are billed independently.
Extra services during the same visit
If your doctor discusses a new problem during the visit, the office may bill a separate problem-focused visit alongside the preventive one. You might owe a copay for that part. It is not wrong, but it is worth asking about up front.
Grandfathered plans
A small number of older plans that have not changed substantially since March 2010 are exempt from the rule. They are increasingly rare, but your plan documents will say if the plan is grandfathered.
Frequency and age limits
Plans can apply reasonable limits, such as covering one routine screening per year. They may also use “reasonable medical management,” for example choosing a particular brand of preventive medication but offering an exception process if your doctor shows a medical need.
A Worked Example
Here is an illustrative scenario with made-up numbers. Maria is 47 and has an in-network primary care doctor. Her annual preventive visit includes a blood pressure check, a depression screening, a flu shot and a referral for a first colonoscopy. The visit is billed as preventive, so she pays $0.
During the same visit she mentions a rash that has been itching for two weeks, and the doctor examines it and writes a prescription. The office adds a separate problem visit charge, and her plan applies a $35 copay for it. Her colonoscopy, scheduled at an in-network center, is covered at no cost as a screening. A polyp is found and removed, and the plan treats that as part of the same procedure. In total she pays $35, plus whatever her pharmacy benefit charges for the prescription. The lesson is that preventive coverage is generous, but any extra service attached to it may be billed under normal rules.
How This Fits With High-Deductible Plans and HSAs
Preventive care is one of the few things a high-deductible health plan can cover before you reach your deductible. That matters if you are weighing a lower premium against higher out-of-pocket exposure. Our article on high-deductible health plan pros and cons explains how this works with a health savings account, and HSA vs FSA compares the account options.
Steps to Use Your Preventive Benefits Well
- Find your plan’s preventive list. Log in to your insurer’s member portal, or call the number on your card, and ask for the preventive services schedule.
- Book an annual visit with an in-network primary care provider. Say it is a preventive or wellness visit when you schedule.
- Ask which screenings you are due for. Your age, family history and personal history affect the list.
- Verify the facility and lab. Ask whether they are in-network and how the service will be coded.
- Keep your explanation of benefits. If you receive a bill for something that should have been free, compare it to the explanation of benefits and call the insurer.
- Appeal if needed. A miscoded preventive claim can often be corrected. See how to appeal a denied health insurance claim.
Frequently Asked Questions
Is an annual physical always free?
A preventive visit is generally covered at no cost in-network, but a visit focused on a medical problem is billed differently. The label on the claim matters.
Do I have to meet my deductible first?
No. Covered preventive services must be provided without cost sharing, so the deductible does not apply to them when billed correctly.
Are vaccines covered?
Vaccines recommended by the CDC’s advisory committee are covered without cost sharing under most plans, usually in-network or at a participating pharmacy. Ask the pharmacy to verify.
Does Medicare have free preventive care too?
Yes, Medicare covers many preventive services, and some are free while others carry a share of the cost. The rules differ from private plans, so check Medicare.gov.
What if my doctor orders a test that is not on the recommended list?
It may still be covered as medically necessary, but it would follow your normal deductible and coinsurance rules rather than the no-cost preventive rule.
Is birth control really free?
Many plans cover FDA-approved contraceptive methods without cost sharing, but some employers and plan types are exempt on religious or moral grounds, and plans may use formularies. Confirm your specific plan.
How do I know if my plan is grandfathered?
Your summary plan description should say so. If you cannot find it, HR or the insurer can confirm it.
Bottom Line
Free preventive care under the ACA is one of the most useful benefits in health insurance, yet many people skip it or get billed by mistake. Stay in-network, understand the difference between a screening and a diagnostic test, and ask how a visit will be coded before you go. Used well, these benefits can help you find problems early without spending a dollar of your deductible. You can also build habits that support what your doctor finds, such as the ones in daily habits that improve your health.
