Key Takeaways

Preventive care is covered at $0 on all ACA-compliant plans, with no copay or deductible required.

Covered services include USPSTF Grade A and B screenings, routine immunizations, and annual wellness visits.

Short-term health plans and grandfathered plans are exempt from the ACA's no-cost preventive care mandate.

Seeing an out-of-network provider for a preventive service means cost-sharing rules apply and the $0 benefit does not.

What Is Preventive Care?

Preventive care is a specific set of services defined by federal guidelines, not every routine appointment where nothing seems wrong. Under the Affordable Care Act, these services are designed to detect or prevent illness before symptoms appear. On ACA-compliant health insurance plans, they're covered at $0, with no copay and no deductible.

The ACA mandates $0 cost-sharing for preventive services on qualifying plans, with no deductible applied first
Covered services include USPSTF Grade A and B recommendations, ACIP immunizations, and HRSA preventive care guidelines
The $0 requirement applies only when the visit is coded as preventive, not when a diagnosis or treatment is delivered in the same visit
Short-term health plans and grandfathered plans are not required to follow ACA preventive care rules
"Routine" or "wellness" visit language on an Explanation of Benefits does not guarantee $0 cost if the provider codes the visit differently

What Does Preventive Care Cover?

Three federal bodies: the U.S. Preventive Services Task Force (USPSTF), the Advisory Committee on Immunization Practices (ACIP), and the Health Resources and Services Administration (HRSA) determine which services qualify as preventive care under the ACA.

Annual Wellness Visits

ACA plans cover one annual wellness visit per year at no cost for adults. The visit must be billed as a wellness or preventive visit, not a sick visit, for the $0 cost rule to apply.

Cancer Screenings

Screenings with a USPSTF Grade A or B rating are covered at $0, including colorectal cancer screening, mammograms, cervical cancer screening, and lung cancer screening for high-risk adults. Age and frequency eligibility rules apply.

Immunizations

Vaccines recommended by the ACIP for routine use are covered at $0 on ACA plans, including flu shots, the COVID-19 vaccine (subject to plan year and legal requirements), HPV vaccine and shingles vaccine. The plan covers both the administration fee and the vaccine itself.

Blood Pressure and Cholesterol Screening

Preventive screenings for hypertension and high cholesterol are covered at no cost for adults within USPSTF-recommended age ranges. If a diagnosis follows the screening, follow-up treatment visits are typically subject to normal cost-sharing.

Prenatal and Pediatric Preventive Care

ACA plans cover prenatal care visits, gestational diabetes screening and HRSA-recommended preventive services for infants, children, and adolescents at $0. Well-child visits are covered from birth up to age 21.

Depression and Substance Use Screening

Depression screening for adults and adolescents and alcohol misuse counseling carry a USPSTF Grade B rating and are covered at $0. Behavioral health preventive services are included in the ACA's Essential Health Benefits framework.

What Preventive Care Does Not Cover

Not every doctor visit qualifies for $0 coverage under ACA preventive care rules. Out-of-network visits, treatment delivered during a preventive appointment, services with a USPSTF Grade C or D rating, and visits on non-ACA plans can all generate charges. The main reason a plan can bill you after a preventive visit: if the provider adds a diagnosis code or delivers treatment during the same appointment, that portion of the claim is no longer governed by the ACA's no-cost mandate.

Out-of-Network Provider Visits

The $0 cost rule applies only to in-network providers. Receiving a USPSTF-recommended screening from an out-of-network provider means your standard deductible, copay and coinsurance rules apply instead.

Treatment Delivered During a Preventive Visit

When a provider diagnoses a condition or delivers treatment during the same appointment as a preventive service, the visit may be split-billed. The preventive portion remains $0, but the treatment portion is subject to normal cost-sharing.

Services Not Yet Rated Grade A or B

Services with a USPSTF Grade C, D, or I rating are not mandated to be covered at $0. Some plans choose to cover them, but ACA law does not require it. Check your plan's Summary of Benefits and Coverage to confirm.

Grandfathered and Short-Term Plans

Plans in effect before March 23, 2010 that qualify as grandfathered, and short-term health plans, are not subject to the ACA's preventive care mandate. Cost-sharing for preventive services on these plans depends entirely on each plan's own terms.

Coverage applies only to ACA-compliant plans. Grandfathered plans and short-term health plans may not include no-cost preventive care.

How Does the No-Cost Preventive Care Rule Work?

The $0 rule activates only when your provider codes the visit correctly as preventive. On ACA-compliant plans, the deductible is bypassed entirely, the law prohibits insurers from applying a deductible before covering USPSTF Grade A and B services or ACIP immunizations. You owe nothing out of pocket for these services regardless of whether you've met your annual deductible, as long as you stay in-network and the visit is billed as preventive under CMS guidelines.

A common billing scenario that produces unexpected charges: when your provider adds a diagnosis code to a preventive visit, the plan may split the claim into two parts. The preventive element stays at $0. The diagnostic or treatment element is processed under your normal coinsurance and copay rules. This outcome reflects how ACA billing rules work in practice, not a plan error.

GETTING BILLED AFTER A FREE PREVENTIVE VISIT?

Before your appointment, ask the provider's billing office to code the visit as preventive-only and to schedule any follow-up concerns as a separate appointment. If a bill arrives for a visit you believe should have been $0, request an itemized statement showing the billing codes used, then contact your insurer to ask whether a preventive-coding correction can be submitted by the provider.

Preventive Care vs. Diagnostic Care: What Is the Difference?

The distinction between preventive and diagnostic care isn't about which service you receive, rather it's about why the provider ordered it and how it's billed. The same blood test can be preventive (no charge) or diagnostic (subject to your deductible) depending on the clinical reason documented at the visit. Intent and billing code determine your cost.

Feature	Preventive Care	Diagnostic Care
What it is	A service delivered to detect or prevent illness before symptoms appear	A service ordered to investigate an existing symptom, complaint, or prior abnormal finding
When it applies	Routine checkup, age-appropriate screening, or USPSTF-recommended service	Follow-up to a positive screening, evaluation of a patient complaint, or monitoring a known condition
Cost-sharing on ACA plan	$0 (no copay, no deductible) when in-network	Subject to your plan's deductible, copay, and coinsurance
Who determines the coding	The provider, based on the clinical reason for the visit	The provider, based on the clinical reason for the visit
What changes the classification	Adding a diagnosis code to the visit or ordering additional tests based on a finding	N/A
Real-world example	A colonoscopy ordered at age 45 with no prior symptoms is coded preventive: $0	A colonoscopy ordered because of rectal bleeding is coded diagnostic: your deductible applies

Confirm how your plan codes specific services in the Summary of Benefits and Coverage before your appointment.

Before a scheduled screening, ask the provider's billing office how the visit will be coded. If the provider plans to review a prior finding during the same appointment, ask whether that converts the visit to diagnostic and whether that portion can be scheduled separately to preserve $0 cost on the preventive element.

Which Health Insurance Plans Must Cover Preventive Care at No Cost?

ACA-compliant individual and small group plans, whether sold on or off the Marketplace, must cover USPSTF Grade A and B services, ACIP immunizations, and HRSA preventive care at $0. This is a legal requirement, not an optional benefit. The ACA's preventive care mandate under PHSA Section 2713 applies to all non-grandfathered group health plans and individual plans, regardless of employer size. Reviewing the best health insurance companies can help you identify plans that go beyond the federal minimum.

Three plan types are exempt from the no-cost preventive care mandate.

Grandfathered plans those in effect before March 23, 2010 that haven't undergone material changes since are not required to comply.
Short-term health plans are not ACA-compliant and can impose deductibles and copays on any service, including screenings.
Some self-insured employer plans that qualify for the grandfathered exemption also fall outside the mandate.

If you're unsure whether your current coverage qualifies, the plan's Summary of Benefits and Coverage will state whether it meets minimum value under the ACA. You can also compare options through the Health Insurance Marketplace or browse most affordable health insurance options for ACA-compliant plans at various price points.

Preventive Care: Bottom Line

ACA-compliant plan members are entitled to free preventive care. Screenings, vaccines, and wellness visits covered under USPSTF Grade A or B ratings cost nothing when you stay in-network and the visit is coded correctly. Short-term and grandfathered plans don't qualify. To confirm your services are covered, review your plan's Summary of Benefits and Coverage and ask your provider's billing office how each visit will be coded before you arrive. The average cost of health insurance already factors in these mandated benefits, make sure you're using them.

Preventive Care: FAQ

We've answered the most frequently asked questions about preventive care in health insurance:

Does preventive care count toward my deductible?

No. ACA-compliant plans must cover USPSTF Grade A and B services at $0 with no deductible applied — the law explicitly prohibits insurers from requiring you to meet your deductible first. One exception applies to split-billing: if your provider adds a diagnosis code during the same visit, the diagnostic portion of the claim is subject to your normal cost-sharing, even on a fully ACA-compliant plan.

Is an annual physical the same as a preventive care visit?

It depends on how it's billed. An annual wellness visit coded as preventive qualifies for $0 cost-sharing under the ACA. If your provider addresses a health concern, reviews a chronic condition, or adds a diagnosis code during the same appointment, that portion may be split-billed and processed under your normal copay and coinsurance schedule — even if the visit felt routine.

Does preventive care apply to my short-term health plan?

No. Short-term health plans are not ACA-compliant and are not required to cover any service at $0, including USPSTF-recommended screenings or ACIP immunizations. Cost-sharing for preventive services on a short-term plan depends entirely on that plan's own terms and benefit schedule, which vary by issuer.

What happens if I see an out-of-network provider for a preventive service?

The $0 rule does not apply to out-of-network providers. Receiving a USPSTF-recommended screening outside your plan's network means your standard deductible, copay, and coinsurance rules apply — the same as any other out-of-network visit. Always confirm your provider is in-network before scheduling a preventive screening to avoid unexpected out-of-pocket costs.

Are preventive care services the same on every ACA plan?

The federally mandated list is consistent across all ACA-compliant plans: services with USPSTF Grade A or B ratings, ACIP immunizations, and HRSA preventive guidelines are covered at $0. Individual plans may voluntarily cover additional services beyond the mandate, but they cannot cover fewer. Review your plan's Summary of Benefits and Coverage for the full list of covered preventive services and any frequency or age restrictions that apply.

Does Medicare cover preventive care at no cost?

Medicare Part B covers many preventive services at $0, including the Annual Wellness Visit, certain cancer screenings, cardiovascular disease screenings, and diabetes prevention programs — when you see a provider who accepts Medicare assignment. The covered service list and eligibility rules differ from ACA Marketplace plans. Comparing Medicare Advantage plans can help you find a plan that fits your preventive care needs.
