Yes, a yearly physical is generally considered preventive care, and most health insurance plans are required to cover it at no cost to you. Under the Affordable Care Act, non-grandfathered plans must cover preventive services without charging a copay, coinsurance, or deductible. But there’s an important catch that trips up millions of people every year: what starts as a preventive visit can quickly become a diagnostic one, and that’s when surprise bills show up.
What the Law Actually Requires
The ACA requires non-grandfathered health plans to cover preventive services that carry an “A” or “B” rating from the U.S. Preventive Services Task Force, along with immunizations recommended by the CDC and additional screenings for women, children, and adolescents supported by federal guidelines. These services must be offered with zero cost-sharing, meaning you pay nothing out of pocket when you receive them from an in-network provider.
The specific preventive services covered at no cost include a wide range of screenings and checks:
- Cancer screenings: mammograms for women 40 to 74, cervical cancer screening for women 21 to 65, colorectal cancer screening for adults 45 to 75, and lung cancer screening for long-term smokers aged 50 to 80
- Heart and metabolic health: blood pressure screening for adults 18 and older, diabetes screening for adults 35 to 70 who are overweight, and cholesterol-related interventions for adults 40 to 75 with risk factors
- Infectious disease testing: HIV screening for ages 15 to 65, hepatitis B and C screening, and syphilis screening for those at increased risk
- Mental health: depression screening for adults and adolescents, anxiety screening for adults and children 8 and older, and screening for unhealthy alcohol and drug use
- Routine vaccinations: flu, COVID-19, pneumonia, and other recommended immunizations
Your annual physical is the visit where most of these screenings happen. The exam itself typically includes measuring your height, weight, and blood pressure, checking blood sugar and cholesterol risk, discussing age-appropriate cancer screenings, evaluating for depression, and reviewing your vaccination status.
How a Free Visit Becomes a Paid One
This is where most confusion and frustration comes from. A preventive visit covers routine checkups when nothing is wrong. Diagnostic care kicks in the moment you bring up a specific symptom, discuss an ongoing condition, or your provider investigates something that doesn’t look right.
The same service can be billed either way depending on the reason behind it. A mammogram ordered as part of routine age-based screening is preventive. A mammogram ordered because you found a lump is diagnostic, and your normal cost-sharing applies. The distinction isn’t about the test itself; it’s about why the test was ordered.
Here’s what catches people off guard: if you mention a new symptom or discuss a chronic condition during your annual physical, your provider may bill part of the visit as a separate diagnostic encounter. Your preventive exam stays covered at no cost, but the additional evaluation for that knee pain or medication adjustment for your blood pressure can generate a separate charge. Your provider’s office documents both services independently, and the diagnostic portion goes through your plan like any other office visit, potentially subject to your copay and deductible.
This doesn’t mean you should avoid mentioning health concerns during your physical. It means you should know that doing so may result in two charges on your statement: one at $0 for the preventive portion, and one at your normal cost-sharing rate for the diagnostic portion.
Medicare Covers Wellness Visits, Not Physicals
If you’re on Medicare, the rules are different in a way that matters. Medicare covers an Annual Wellness Visit at no cost, but this is explicitly not a physical exam. The wellness visit focuses on updating a personalized prevention plan based on your health risks. It includes a health risk questionnaire, a review of your medical and family history, routine measurements like height, weight, and blood pressure, a cognitive assessment for signs of dementia, a review of your prescriptions, and a screening schedule for future preventive services.
What it does not include is a traditional head-to-toe physical examination. Medicare does not cover routine physicals. If your provider performs one during your wellness visit, or if you request additional tests that go beyond what the wellness visit covers, you may owe the full cost out of pocket. New Medicare enrollees also have access to a one-time “Welcome to Medicare” preventive visit, which must occur within the first 12 months of Part B enrollment. Your first Annual Wellness Visit cannot take place within 12 months of that initial visit, though you don’t need the Welcome to Medicare visit to qualify for annual wellness visits going forward.
Plans That Don’t Have to Cover It
The ACA’s preventive care mandate does not apply to grandfathered health plans. These are plans that existed before March 23, 2010, and have not made significant changes to their cost-sharing structure, benefits, or employer contribution levels since then. Grandfathered plans are not required to offer free preventive care, though some do voluntarily. If you’re unsure whether your plan is grandfathered, your benefits summary or your insurer’s customer service line can tell you. The number of grandfathered plans shrinks every year, but they still exist.
In-Network Providers Matter
Even with a non-grandfathered plan, the no-cost guarantee only applies when you see an in-network provider. Insurance plans are not required to waive cost-sharing for preventive services delivered out of network. The one exception is when no in-network provider is available to deliver the service, in which case the plan must still cover it without cost-sharing. In practice, this means scheduling your annual physical with an in-network doctor is one of the simplest ways to protect yourself from an unexpected bill.
How to Keep Your Visit Fully Covered
When you schedule, ask for a “preventive” or “wellness” visit specifically. Some offices schedule these differently from problem-focused appointments, allotting different time and using different billing codes from the start. Providers bill preventive physicals under a distinct set of procedure codes reserved for comprehensive preventive evaluations, and using the right code is what triggers your plan to process the visit at zero cost.
During the visit, be aware that raising new concerns is completely appropriate, but understand the billing implications. If your provider needs to evaluate a new problem or manage an existing condition beyond simple screening, that work will likely be billed separately. You can always ask your provider’s billing staff beforehand how they handle situations where a preventive visit overlaps with diagnostic care. Some offices will let you know in the moment if something is about to shift the visit into billable territory, giving you the option to schedule a follow-up instead.
Checking your explanation of benefits statement after the visit is also worth the two minutes it takes. Look for two separate line items if your provider addressed both preventive and diagnostic concerns. The preventive portion should show $0 in patient responsibility. If it doesn’t, and you saw an in-network provider for standard screenings, it’s worth calling your insurer to ask why.
