Which Preventive Screenings Are Free With Insurance?
A routine colonoscopy costs $0 with a non-grandfathered ACA-compliant plan when you stay in network. Delaying that same screening until symptoms appear could mean treatment costs that can directionally exceed $120,000 for late-stage colorectal cancer. Understanding which preventive screenings are free with insurance is a critical financial decision, not just a health one. This guide breaks down the no-cost covered tests, the high cash prices you avoid, and the exact steps to ensure you don’t get a surprise bill.
How This Guide Was Built
This financial guide synthesizes data from the U.S. Preventive Services Task Force (USPSTF) A/B recommendations, the Kaiser Family Foundation’s (KFF) analysis of ACA preventive-service coverage, and published consumer cost sources. We did not run these screenings hands-on — this is a financial analysis based on official coverage rules and published cost data. Last verified: August 2026.
Which Preventive Screenings Are Free With Insurance?
Non-grandfathered, ACA-compliant private health plans must cover USPSTF A/B-rated preventive services at $0 with no copay, deductible, or coinsurance when performed by an in-network provider. This core protection applies to screenings like colonoscopies, mammograms, and blood pressure checks, but excludes grandfathered plans, out-of-network care, and diagnostic follow-ups triggered by a screening result (KFF).
Preventive Screenings by Age
USPSTF and HRSA guidelines specify recommended age ranges for key preventive services: colorectal cancer screening begins at age 45, mammography at 40, cervical screening at 21, and lung cancer screening at 50 for eligible smokers. Blood pressure screening applies to all adults aged 18–79. For specific intervals, consult the linked resources below (KFF; USPSTF).
What Preventive Screenings Cost With and Without Insurance
When covered as a preventive service under an ACA-compliant plan, a screening typically costs $0 out of pocket. Without insurance, cash prices vary widely—a mammogram may run about $400, while a colonoscopy can exceed $2,300. A screening’s price differs from any diagnostic follow-up costs it may reveal (GoodRx; MDsave).
The Biggest Potential Savings: Colorectal Screening
A screening colonoscopy averages roughly $2,322 out of pocket, with a typical range from $1,243 to $4,142. At-home FIT or FIT-DNA tests like Cologuard cost significantly less. With ACA-compliant insurance, covered screening is $0. Treatment for late-stage colorectal cancer can directionally exceed $120,000 in the first year, underscoring early detection’s value (MDsave; CoveredUSA; USPSTF).
Mammograms, Follow-Up Imaging, and the $0 Coverage Expansion
Without insurance, a standard 2D mammogram typically costs between $100 and $600, with a national average near $400. For plan years beginning after December 30, 2025, ACA-compliant plans are required to cover not just the mammogram but also additional diagnostic imaging, pathology, and navigation services needed to complete a breast-cancer screening at $0 cost (GoodRx; Parrott Benefit Group).
How to Get Preventive Screenings at $0
To secure $0 coverage, confirm the service is coded as preventive, not diagnostic. Always use an in-network clinician and facility. Ask the provider’s billing department how the claim will be coded, and verify that any lab fees fall under the preventive benefit. Calling your insurer before scheduling confirms $0 coverage applies to your specific procedure (KFF).

When a “Free” Screening Can Still Generate a Bill
$0 coverage is not automatic; it depends on your plan being non-grandfathered, the provider being in-network, and the service being billed with preventive codes. Diagnostic services, care from out-of-network providers, noncovered plan designs, and any follow-up triggered by symptoms or screening results may not be covered at $0 and can lead to cost-sharing (KFF).
FAQ
Are all preventive screenings free with insurance?
Only services rated A or B by the USPSTF must be covered at $0 by non-grandfathered ACA-compliant plans when delivered in network. Grandfathered plans, short-term health insurance, and certain employer-sponsored plans are not required to offer this coverage, so always verify your specific plan’s benefits (KFF).
Is a colonoscopy free if a polyp is removed?
Not necessarily. If a screening colonoscopy becomes diagnostic (e.g., due to polyp removal), the billing codes change and cost-sharing may apply. The supplied materials do not verify every billing scenario; you must call your insurer before the procedure to confirm coverage (KFF).
Can I get a free mammogram without insurance?
Federally funded programs, like the CDC’s National Breast and Cervical Cancer Early Detection Program, may offer free mammograms to eligible low-income, uninsured individuals. Availability varies by state; contact your state health department to confirm eligibility and find participating providers near you (GoodRx).
Bottom Line: Schedule the $0 Services Before They Become Expensive
Take these steps now: verify your plan’s preventive-care eligibility, confirm your chosen provider is in-network, ask about billing codes, and book recommended screenings before your schedule lapses. A $0 colonoscopy or mammogram today can help you avoid five- or six-figure treatment costs later.
