Preventive Care: Free Health Services Your Insurance Must Cover at No Cost
The ACA Preventive Care Mandate
Under the Affordable Care Act, all ACA-compliant health insurance plans must cover a comprehensive list of preventive services at zero cost to you — no copay, no coinsurance, no deductible. These services are free regardless of whether you have met your annual deductible. This is one of the most valuable and most underused benefits in health insurance.
The logic is straightforward: catching health problems early through screening and prevention is dramatically cheaper than treating them after they have progressed. A $200 colonoscopy that detects a precancerous polyp saves the insurance system $200,000 in cancer treatment. Insurers cover preventive care for free because it reduces their long-term claims costs. You benefit by getting essential health monitoring without financial barriers.
Preventive Services for All Adults
Annual wellness visits with your primary care physician are covered at no cost. These are not the same as sick visits — the wellness visit is specifically for preventive screening, health assessment, and counseling. Blood pressure screening at every visit. Cholesterol screening for adults at elevated risk, typically starting at age 20. Type 2 diabetes screening for adults with high blood pressure. Depression screening. Obesity screening and counseling. Alcohol misuse screening and counseling. Tobacco use screening and cessation interventions including FDA-approved medications. Immunizations including flu, tetanus, hepatitis, shingles, and others recommended by the Advisory Committee on Immunization Practices.
Cancer Screenings
Colorectal cancer screening starting at age 45 through various methods including colonoscopy, stool-based tests, and CT colonography. Lung cancer screening with low-dose CT for adults 50 to 80 with a significant smoking history. Cervical cancer screening (Pap smear and HPV testing) for women. Breast cancer screening (mammography) for women over 40. These are all covered at 100 percent with no cost-sharing.
Women-Specific Preventive Services
Contraception — all FDA-approved contraceptive methods, sterilization procedures, and patient education. Well-woman visits. Breastfeeding support, supplies, and counseling. Gestational diabetes screening. Domestic violence screening and counseling. HPV testing. Osteoporosis screening for women over 60. These services address health needs specific to women and are covered without cost-sharing.
Children and Adolescent Services
Well-child visits from birth through age 18 at recommended intervals. Vision and hearing screening. Developmental screening. Autism screening at 18 and 24 months. Behavioral assessments. Immunizations per the recommended childhood schedule. Obesity screening and counseling. Depression screening for adolescents. Dental coverage through age 18 in marketplace plans. All at zero cost.
The Catch: Preventive vs Diagnostic
The free coverage applies only when the service is preventive — meaning it is performed on someone without symptoms as a routine screening. If the same test is performed because you reported symptoms, it becomes diagnostic and is subject to your deductible and cost-sharing. A colonoscopy performed as a routine age-based screening is free. The same colonoscopy performed because you reported rectal bleeding is diagnostic and may cost you hundreds or thousands depending on your plan.
This distinction creates confusion and unexpected bills. When scheduling preventive services, explicitly tell your provider the visit is for routine preventive screening. Confirm that the billing code will reflect a preventive visit. If a screening discovers something that requires follow-up during the same visit — a polyp removed during a screening colonoscopy, for example — ask your insurer in advance how the follow-up will be billed. Some insurers cover polyp removal as part of the preventive screening. Others bill it separately as a procedure subject to your deductible.
Use These Services
You are paying premiums that include the cost of preventive care whether you use it or not. Skipping free screenings does not save you money — it just means you are paying for services you are not receiving while potentially missing early detection of serious conditions that are cheaper and more treatable when caught early. Schedule your annual wellness visit, stay current on recommended screenings for your age and risk factors, and get your immunizations. It is free. Use it.
