Which preventive screenings are covered free by insurance?

Under the ACA, most preventive screenings with an A or B rating from the U.S. Preventive Services Task Force (USPSTF) are covered at 100% with no copay at in-network providers. This includes blood pressure screening, cholesterol testing, colorectal cancer screening, mammograms, cervical cancer screening (Pap smears), and depression screening, among others. Screenings with a C or I rating may require cost-sharing.

What's the difference between a preventive screening and a diagnostic test?

A preventive screening is ordered proactively for someone without symptoms to detect disease early. A diagnostic test is ordered because a symptom, prior result, or risk factor indicates a problem may exist. Insurance coverage differs significantly — a screening mammogram for a woman with no symptoms may be fully covered, while a diagnostic mammogram ordered because of a lump may trigger a deductible or copay.

How much does a colonoscopy cost without insurance in 2026?

A colonoscopy without insurance costs $1,800 to $3,500 at most facilities, with urban markets on the higher end. Community health centers and ambulatory surgery centers typically charge 30–50% less than hospital outpatient settings for the same procedure. Cash-pay negotiated rates are frequently available and can reduce costs to $900–$1,800.

At what age should I get my first colonoscopy?

The USPSTF recommends colorectal cancer screening starting at age 45 for average-risk adults — down from 50 in prior guidelines. People with a first-degree relative diagnosed with colorectal cancer before age 60 should begin screening at age 40 or 10 years before the relative's diagnosis, whichever comes first.

Do I need a doctor's order to get preventive screenings?

Most preventive screenings require a physician or nurse practitioner order to be covered by insurance. Some labs (Quest, LabCorp) allow direct-pay ordering for cholesterol panels and metabolic tests without a physician order, typically for $40–$80 — useful for uninsured patients or those who want results before seeing a doctor.

Preventive Health Screenings by Age: What to Get and What They Cost in 2026

June 10, 2026 · Guide · 6 min read

Preventive screenings catch disease before symptoms appear — when treatment is cheapest and outcomes are best. The USPSTF (U.S. Preventive Services Task Force) publishes evidence-based recommendations for each screening by age and risk group; most A and B-rated screenings are fully covered by insurance under the ACA with no cost-sharing at in-network providers. This guide maps the recommended screenings decade by decade, with 2026 self-pay costs for the uninsured.

Why Preventive Screenings Save More Than They Cost

Stage 1 colorectal cancer has a 5-year survival rate above 90%. Stage 4 colorectal cancer: below 15%. The difference between those outcomes is typically a colonoscopy catching polyps before they become cancer — at a cost of $1,800 to $3,500, fully covered by most insurance as preventive care. The economics of prevention are not subtle: the USPSTF estimates that each preventive colonoscopy generates approximately $9,000 in net health cost savings over a patient's lifetime through avoided treatment costs.

Yet CDC data shows that fewer than 75% of eligible adults have received a colorectal cancer screening, and fewer than 60% of adults maintain current cervical cancer screening. Cost is one barrier — but for most insured adults, these screenings cost nothing out-of-pocket. The barrier is more often scheduling friction and not knowing what to prioritize.

Screening by Age Group

Ages 18–29

Young adults have fewer chronic disease screenings but several important preventive measures:

Blood pressure: Annual screening at every office visit. Target: below 120/80. Covered at no cost under ACA. Self-pay: $0 (available at most pharmacies with automated cuffs).
Cervical cancer (Pap smear): Every 3 years starting at age 21 for average-risk women. Combined Pap + HPV co-testing every 5 years from age 25. Covered under ACA. Self-pay: $80–$200 for the test alone; $150–$350 all-in at an OBGYN office visit.
STI screening: Annual chlamydia and gonorrhea screening for sexually active women under 25 and for men who have sex with men. HIV screening at least once for all adults 15–65; more frequently for those at higher risk. Covered under ACA. Self-pay: $80–$180 for comprehensive STI panels through community health centers or direct-pay labs.
Depression screening: Recommended by USPSTF for all adults. Covered under ACA. Typically administered as a PHQ-9 questionnaire during an office visit.
BMI and obesity screening: Calculated at every visit. BMI above 30 triggers a referral recommendation for behavioral counseling.

Ages 30–39

Blood pressure: Continue annual screening. High blood pressure affects approximately 25% of adults in their 30s and is often asymptomatic.
Cervical cancer: Pap + HPV co-testing every 5 years (or Pap alone every 3 years) continues through age 65.
Cholesterol (lipid panel): Baseline lipid panel recommended by age 35 for men; for women and younger adults with risk factors (family history, diabetes, obesity) earlier screening is warranted. Covered under ACA for high-risk individuals. Self-pay: $30–$80 for a lipid panel at direct-pay labs; $150–$350 all-in at a physician office.
Diabetes (prediabetes) screening: USPSTF recommends screening adults aged 35–70 who are overweight or obese. A fasting blood glucose or HbA1c test. Covered under ACA for eligible patients. Self-pay: $25–$60 for a standalone HbA1c test.
Breast cancer: Average-risk women should discuss mammogram timing with their provider between ages 40–50. Women with BRCA1/2 mutations or first-degree relatives with breast cancer before 50 should begin earlier.

Ages 40–49

This is the decade when chronic disease prevention becomes most time-sensitive:

Mammogram: USPSTF recommends biennial mammograms starting at 40 for average-risk women. American Cancer Society recommends annual starting at 45. Both are covered under ACA. Self-pay: $150–$350 for a standard mammogram; $250–$600 for 3D mammography (tomosynthesis), which is not always covered.
Colorectal cancer screening: Begins at 45 for average-risk adults. Options include: colonoscopy every 10 years ($1,800–$3,500 self-pay), Cologuard stool DNA test every 3 years ($600–$700 self-pay), or annual FIT (fecal immunochemical test) stool test ($25–$50 self-pay). Covered under ACA when ordered as preventive.
Blood pressure: More frequent monitoring warranted if previous readings were elevated. Home blood pressure monitors cost $30–$80.
Blood glucose/diabetes: Screen all overweight/obese adults 35–70. HbA1c above 5.7% indicates prediabetes; above 6.5% indicates diabetes.
Lung cancer: Annual low-dose CT scan for adults 50–80 with a 20 pack-year smoking history who currently smoke or quit within the last 15 years. Covered under ACA. Self-pay: $150–$400.

Ages 50–59

Colorectal cancer: Continue screening per chosen method. If Cologuard or FIT returns a positive result, colonoscopy is required — and the follow-up colonoscopy may be billed as diagnostic, not preventive, affecting cost-sharing.
Breast cancer: Continue biennial or annual mammograms based on individual risk profile and provider guidance.
Osteoporosis: Bone density scan (DEXA) is recommended for women 65+, but earlier if risk factors exist (smoking, family history, low BMI, early menopause, corticosteroid use). Self-pay: $150–$350.
Abdominal aortic aneurysm (AAA) screening: One-time ultrasound screening for men aged 65–75 who have ever smoked. Covered under Medicare and most private insurance. Self-pay: $200–$500.
Hepatitis C: One-time hepatitis C screening for all adults born between 1945 and 1965 (baby boomers). Covered under ACA. Self-pay: $40–$100.
Shingles vaccine: Two doses of Shingrix recommended at age 50+. Covered by most insurance. Self-pay: $180–$220 per dose.

Ages 60–69

Bone density (DEXA): All women 65+; men with risk factors. Self-pay: $150–$350.
Cognitive screening: No USPSTF recommendation for routine cognitive screening in asymptomatic adults — annual wellness visits include informal assessment. If concerned about memory, the Montreal Cognitive Assessment (MoCA) is a validated 10-minute tool your physician can administer.
Hearing: No USPSTF screening recommendation, but audiologist hearing test ($0–$75 at most practices as a screening visit) is prudent by age 65 as a baseline.
Vision: No USPSTF recommendation, but annual or biennial eye exams are recommended by the American Academy of Ophthalmology starting at 65. Self-pay: $100–$200 for a comprehensive exam.
Continue all prior screenings at recommended intervals.

Understanding Insurance Coverage for Screenings

The ACA mandates that non-grandfathered health plans cover USPSTF A and B-rated preventive services with no cost-sharing when received from in-network providers. The critical nuances:

In-network only. The same colonoscopy at an out-of-network facility may not be covered — or may apply to your deductible. Always confirm in-network status before scheduling.
Preventive vs. diagnostic billing matters. If your doctor adds a problem to the visit (discusses a symptom or chronic condition), the billing code can shift from preventive (100% covered) to office visit (cost-sharing applies). Ask the biller to keep preventive services on separate claims if your visit combines preventive and problem-oriented care.
Grandfathered plans are exempt. Plans that existed before March 23, 2010 and have not changed substantially are not required to cover preventive services without cost-sharing.

The guide to ACA preventive care coverage covers all USPSTF A and B-rated services and how to resolve billing disputes when a covered preventive service is incorrectly billed with cost-sharing. And the annual physical cost guide explains exactly what is and is not covered under the ACA wellness visit — a common source of unexpected bills when patients assume everything discussed is covered.

Self-Pay Strategies for the Uninsured

If you are uninsured, the most important cost reduction strategy is choosing the right facility type:

Federally Qualified Health Centers (FQHCs): Sliding-scale fees based on income; many screenings available for $20–$80 total cost
Direct-pay labs (Quest, LabCorp, Any Lab Test Now): Cholesterol, glucose, HbA1c, hepatitis C, and STI panels at $30–$100 without a physician order
Ambulatory surgery centers vs. hospital outpatient: The same colonoscopy costs 30–50% less at an ASC than at a hospital outpatient department
Community health fairs: Free or low-cost blood pressure, glucose, cholesterol, and skin cancer screenings are offered regularly in most metro areas

For all screenings, ask the provider's billing office for their self-pay or cash rate before scheduling. Published "chargemaster" rates are rarely what an uninsured patient actually pays — negotiated rates are typically 40–70% lower. The guide to doctor visit costs without insurance covers the negotiation approach in detail.

Find clinics near you that publish self-pay rates, or browse healthcare providers by city to compare options in your area.
