Several options exist for getting a free or no-cost checkup in the United States, depending on your insurance status and income. If you have health insurance through an employer or the marketplace, preventive visits are already covered at zero cost to you. If you’re uninsured or underinsured, federally funded health centers, free clinics, local health departments, and university-run clinics all offer checkups on a free or sliding-fee basis.
If You Have Insurance: Preventive Visits Cost $0
Under the Affordable Care Act, most health insurance plans must cover a set of preventive services with no copay, no deductible, and no coinsurance. This includes annual wellness visits, blood pressure checks, diabetes and cholesterol screenings, many cancer screenings (mammograms, colonoscopies), routine vaccinations, flu shots, and counseling for issues like smoking, weight management, and depression. Well-baby and well-child visits are also fully covered.
The key word is “preventive.” If you go in for a wellness visit and the doctor discovers a problem that requires follow-up testing or treatment, those additional services may be billed separately. To avoid surprise charges, schedule your appointment specifically as a preventive or wellness visit and confirm with your insurance beforehand that the provider is in-network. The specific screenings you qualify for depend on your age, sex, and risk factors. Adults 45 to 75 are covered for colorectal cancer screening. Women 40 to 74 are covered for mammograms every two years. HIV screening is covered for everyone ages 15 to 65. Hepatitis C screening is covered for adults 18 to 79.
Federally Qualified Health Centers
If you’re uninsured or can’t afford your plan’s out-of-pocket costs, federally qualified health centers (FQHCs) are the most widely available option. These are community clinics funded by the federal government to serve people regardless of ability to pay. They exist in all 50 states and charge on a sliding fee scale based on your income, meaning visits can be completely free if your earnings are low enough.
You can find the nearest one by visiting findahealthcenter.hrsa.gov, the official search tool run by the Health Resources and Services Administration. Enter your zip code and set a search radius anywhere from 5 to 250 miles. These centers provide physicals, blood work, vaccinations, chronic disease management, and often dental and mental health services. You don’t need to prove citizenship or immigration status to be seen.
Free and Charitable Clinics
Free clinics operate as nonprofits staffed largely by volunteer doctors, nurses, and other healthcare professionals. They typically serve uninsured adults who earn too much for Medicaid but too little for marketplace insurance. Services usually include basic physicals, blood pressure and blood sugar checks, cholesterol panels, and referrals to specialists when needed.
The National Association of Free and Charitable Clinics (nafcclinics.org) maintains a directory you can search by location. Availability varies by region. Some clinics operate only certain days of the week and may require an appointment, so call ahead.
Student-Run Clinics at Medical Schools
Many medical schools operate student-run free clinics that provide checkups to people who are uninsured or underinsured. Medical students perform the visits under the supervision of licensed physicians, and research published in Academic Medicine found that these clinics deliver preventive and primary care at a quality comparable to typical providers. They offer screenings for HIV, cholesterol, blood sugar, depression, anxiety, and substance use, along with vaccinations, blood pressure checks, mammogram referrals, and Pap tests.
Some of these clinics also hold walk-in events like vaccine drives and blood pressure screening days. If you live near a university with a medical school, check its website or call the campus health system to ask about community clinic hours. There’s no centralized directory, so a quick search for “student-run free clinic” plus your city name is the fastest route.
Local Health Departments
City and county health departments commonly offer certain preventive services for free, particularly immunizations, HIV testing, STI screenings, and tuberculosis testing. Not every health department provides full physicals, but many can handle the basics and connect you with a community health center for anything more comprehensive. Search your city or county name plus “department of public health” to find what’s available locally.
CDC Cancer Screening Programs
If you’re specifically concerned about breast or cervical cancer screening, the CDC’s National Breast and Cervical Cancer Early Detection Program provides free or low-cost mammograms and Pap tests to women who are uninsured or underinsured. Eligibility requirements are straightforward: ages 40 to 64 for breast cancer screening, 21 to 64 for cervical cancer screening, and household income at or below 250% of the federal poverty level. For a single person in 2026, that’s roughly $39,900 per year. The program operates through local partners in every state, and you can find your nearest location through the CDC’s website.
How Income Affects Your Options
Most sliding-fee and free programs use the federal poverty level (FPL) as their benchmark. For 2026, the FPL is $15,960 for an individual and $33,000 for a family of four. If your income falls below 100% of FPL, you’ll generally qualify for free services at community health centers and may also be eligible for Medicaid in states that expanded it. Between 100% and 200% of FPL, you’ll typically pay a small fee on the sliding scale. Between 100% and 400% of FPL, you qualify for premium tax credits that can make marketplace insurance (and its free preventive benefits) affordable.
If your income fluctuates or you’re between jobs, don’t assume you need to wait until you have insurance. Community health centers and free clinics are designed precisely for these gaps. Bring a recent pay stub or tax return to help the clinic determine your fee, but most will see you even if you have no documentation at all.
