Do I really need health insurance?

Who this guide is for

You're young, generally healthy, and you're not sure health insurance is worth the money. Maybe you haven't been to a doctor in two years. Maybe you're currently uninsured and weighing whether to enroll. Maybe someone told you it's "just for old people" or "a waste if you're not sick."

This guide doesn't try to talk you into anything. It lays out the actual math: what things cost when you don't have coverage, what coverage costs, and what you get for it. You can do the arithmetic yourself and decide. If you're self-employed and want the fuller picture on coverage strategy, see our guide to health insurance when you're self-employed.

1. Why does insurance matter if I never go to the doctor?

What you're deciding: Whether the logic behind "I don't need insurance because I'm healthy" actually holds up.

The logic isn't unreasonable on its face. If you're in your 20s or 30s, generally healthy, and you rarely see a doctor, it's fair to ask why you'd pay a monthly premium for something you barely use.

Here's the piece that logic misses: insurance was never mainly about routine visits. A yearly checkup and the occasional prescription are small, predictable costs. You could pay for most of those out of pocket without insurance and often come out ahead in a given year.

Insurance is not a subscription to doctor visits. It's a ceiling on financial damage from medical events you can't predict or control. You don't buy homeowners insurance because you expect your house to burn down. You buy it because if it does, the cost would be catastrophic, and insurance caps how much of that cost lands on you.

Health insurance works the same way. The question isn't "will I use a lot of routine care this year?" It's "if something unpredictable happens, how much of the bill am I personally exposed to?" For most healthy young adults, the honest answer without coverage is: all of it, with no ceiling.

That doesn't mean coverage is automatically worth it for everyone at every price. It means the comparison has to include the unpredictable events, not just the routine ones. The next section puts real numbers on those events.

2. What could actually happen without coverage?

What you're deciding: Whether the financial risk of being uninsured is large enough to matter to you.

These aren't worst-case horror stories. They're common events that happen to healthy people regularly, with typical U.S. billed costs for someone with no insurance. Actual costs vary widely by region, hospital, and case severity, so treat these as illustrative ranges, not quotes.

Appendectomy: roughly $30,000-$50,000. Appendicitis doesn't check your health history first. It's one of the most common emergency surgeries in your age group.
Broken leg from a bike or sports accident: roughly $7,500-$35,000, depending on whether it requires surgery, hardware, and physical therapy.
ER visit for chest pain that turns out to be nothing: roughly $2,000-$5,000. Chest pain gets worked up seriously regardless of the eventual diagnosis, and the workup (EKG, bloodwork, imaging, observation) is billed even when you're sent home fine.
ACL tear: roughly $20,000-$50,000 including surgery and rehab. Common in anyone who plays recreational sports.
A mental health crisis requiring ongoing care: roughly $1,000-$2,000 per month for therapy and medication management, and that's before any inpatient stay.
A cancer diagnosis in your 20s or 30s: it happens, and it is not rare enough to dismiss. Treatment costs can run $100,000 or more depending on the cancer type and treatment course.
Being a passenger in a car accident: even when you're not at fault and even when you're generally uninjured going in, an ER visit, imaging, possible surgery, and rehab can add up to tens of thousands of dollars.

None of these require you to have done anything wrong or lived recklessly. That's the point. Insurance isn't a bet against your own bad decisions. It's a bet against the ordinary unpredictability of being a person with a body.

Without coverage, you may be billed the hospital's full list price for all of it, though many hospitals offer discounted cash prices, financial assistance, or charity care, so ask about them. And uninsured care has no spending cap.

3. Is there still a penalty for not having insurance?

What you're deciding: Whether skipping coverage carries a direct financial penalty where you live.

Eligibility check: This depends entirely on your state.

The federal individual mandate penalty (the tax penalty for not having coverage) was reduced to $0 starting in 2019. At the federal level, there is currently no tax penalty for being uninsured.

However, a handful of states and the District of Columbia have their own individual mandates with their own penalties for residents who go without qualifying coverage:

California
Massachusetts
New Jersey
Rhode Island
District of Columbia

Vermont is a separate case: it requires residents to have coverage, but there is no tax penalty attached to its mandate.

If you live in one of these states or DC, check your state's specific rules before assuming there's no cost to going uninsured. If you don't, there's no direct penalty tied to your tax return. But the absence of a penalty doesn't mean the absence of risk. The financial exposure described in the section above is the real "cost" of being uninsured, whether or not your state adds a penalty on top of it.

4. What are my cheapest coverage options?

What you're deciding: Which type of plan fits your budget if cost is your main concern.

This is the central fork in this guide. Before comparing plan types, one thing determines a lot of your options: whether you might qualify for free or low-cost coverage through Medicaid or a subsidized Marketplace plan. If there's a chance you do, that changes the math substantially, so don't rule anything out based on assumed cost. Go to Decision 5 first if you're at all unsure about your income eligibility, then come back here.

If you already know you'll be paying close to full price, here are the lowest-cost legitimate categories, compared honestly.

Catastrophic plans

Eligibility check: Generally available only to people under 30, or anyone with a hardship or affordability exemption regardless of age. For 2027, people whose income is under 100% or over 250% of the federal poverty level (and therefore ineligible for tax credits) can also qualify through a hardship exemption.
Low monthly premium, high deductible.
Covers at least three primary care visits per year and preventive care before you've met your deductible, same as other ACA plans.
After the deductible, covers essential health benefits like any ACA plan.
Who this fits: Younger, healthy consumers who want the lowest possible premium and are comfortable paying most routine costs out of pocket in exchange for protection against a major event.

Bronze plans

Eligibility check: Available to everyone shopping the individual market, no age restriction.
Low premium relative to other metal tiers, high deductible.
Can be paired with a Health Savings Account: starting in 2026, every Marketplace Bronze plan counts as HSA-compatible.
Covers essential health benefits and preventive care at no cost in-network. The plan can't put a yearly or lifetime dollar limit on essential health benefits, and your own yearly spending on covered in-network care is capped by the out-of-pocket maximum ($10,600 in 2026; $12,000 in 2027, individual).
Who this fits: Healthy consumers who want ACA protections (no denial or higher price for pre-existing conditions, a yearly out-of-pocket maximum) at the lowest premium among plans open to everyone. Bronze plans pay about 60% of costs on average, so expect a high deductible; if you qualify for savings, compare Silver.

Short-term medical insurance

Eligibility check: Uses medical underwriting, meaning your health history can get you declined or can result in specific conditions being excluded. Not available in every state; some states ban or heavily restrict it.
Cheaper premiums than ACA plans, sometimes significantly.
Not ACA-compliant: may exclude pre-existing conditions, may not cover essential health benefits, may cap total payouts, and is not minimum essential coverage, so it does not satisfy a state coverage mandate.
Who this fits: Generally healthy people with no ongoing conditions or prescriptions who want a lower premium and understand they're accepting narrower, less certain coverage in exchange.
Who this doesn't fit: Anyone with a pre-existing condition, anyone who wants guaranteed coverage for a serious diagnosis, anyone in a state that restricts these plans.

The honest comparison: Catastrophic and Bronze plans usually cost more per month than short-term plans, but your spending on covered in-network care is capped each year and they can't turn you down or exclude your conditions. That cap does not include premiums, out-of-network care, non-covered services, or balance bills. Short-term plans cost less per month but leave real gaps in exactly the situations described in Decision 2: a new serious diagnosis, a condition you already have, or a payout cap that runs out mid-treatment.

5. Do I qualify for free or low-cost coverage?

What you're deciding: Whether you can get covered for close to nothing before assuming you can't afford insurance at all.

A lot of young adults assume coverage is unaffordable without checking. Two paths are worth ruling out first.

Medicaid

Eligibility check: Income-based. In states that expanded Medicaid, adults generally qualify with household income up to 138% of the federal poverty level. Starting by January 1, 2027, most expansion adults ages 19-64 must also show 80 hours a month of work, school, or community service to keep coverage, with exemptions for certain groups. Eligibility rules and the expansion status vary by state, so whether you qualify depends on where you live and your specific household income.
Medicaid generally has no monthly premium, or a very low one depending on the state.
Many young adults who would qualify never apply because they assume their income is too high or that Medicaid is only for parents or people with disabilities. That assumption is often wrong, especially in expansion states.

$0-premium Marketplace plans

Eligibility check: Depends on your household income relative to the federal poverty level and the subsidy structure in effect for the current plan year.
Depending on income, some consumers, particularly those at the lower end of the eligible range, can still find a Bronze plan with a $0 monthly premium after the premium tax credit. $0-premium plans are less common than in recent years: the enhanced subsidies that drove many of them expired on December 31, 2025.

What to do before assuming you can't afford coverage: Check your eligibility for both before ruling out insurance on cost grounds. The income thresholds and subsidy amounts change from year to year, so even if you didn't qualify in a past year, it's worth checking again for the current one.

6. What does a basic plan actually cover for me?

What you're deciding: Whether even the cheapest ACA plan gives you anything beyond catastrophic protection.

Every ACA-compliant plan, regardless of metal tier, is required to cover the same set of essential health benefits, including:

Recommended preventive care at no cost in-network. Recommended checkups, vaccines, screenings, and contraception are $0 when you use an in-network provider. Which services are free depends on your age and risk (for example, colorectal cancer screening for ages 45-75), and follow-up care or treatment tied to a screening may carry costs.
Mental health and substance use treatment. Covered as an essential health benefit, not an add-on. This matters more than it might seem: mental health care is one of the most commonly used benefits among young adults with coverage.
Prescription drugs. Covered, though your specific costs depend on the plan's formulary and whether you've met your deductible.
Emergency services. Covered as an essential health benefit, and you can't be charged more than the in-network rate for emergency services at an out-of-network hospital or provider. Ground ambulances are not covered by this federal protection and may still bill out-of-network rates unless state law says otherwise.
Lab work. Covered as part of diagnostic services.

This is worth sitting with for a moment if you think of insurance as only mattering when something goes catastrophically wrong. Even the cheapest ACA plan covers recommended preventive care at no cost in-network, and covers mental health and substance use treatment, though copays or deductibles usually apply to treatment. Preventive care catches problems early, before they become the expensive events described in Decision 2. None of this applies the same way to short-term plans, which are not required to cover these benefits.

7. What about just paying cash for care?

What you're deciding: Whether skipping insurance and paying out of pocket for whatever comes up is a workable strategy.

For routine care, the cash-pay math is genuinely reasonable:

Cash-pay urgent care visit: roughly $100-$300.
Cash-pay primary care visit: roughly $75-$250.
Cash-pay prescriptions: varies widely by medication; discount programs can bring costs down significantly for many common drugs.

If your healthcare use in a given year is limited to a couple of routine visits and a prescription or two, paying cash may cost less than a year of premiums. That's a fair, honest comparison, and it's why some healthy people conclude insurance isn't worth it for a "normal" year.

Where the cash-pay strategy breaks down is anything from Decision 2. One ER visit for something that turns out to be serious, one broken bone that needs surgery, one unexpected diagnosis, and the "savings" from years of not paying premiums can be gone in a single bill, with more owed after that.

It's also worth knowing that uninsured patients can be billed higher list prices than insured patients, who benefit from negotiated rates their insurer has already secured with the provider, though many hospitals offer discounted cash prices or financial assistance, so ask before paying. Paying cash doesn't just mean paying the same price without a middleman. It can mean paying more than an insured person would for the same service, unless you get a discounted cash price or financial assistance; compare cash prices and ask for a good faith estimate.

So the cash-pay strategy can work, but only for the routine layer of care. It offers no protection at all for the unpredictable layer, which is the layer that actually creates financial risk.

8. The real math: insured vs. uninsured

What you're deciding: How the numbers actually net out across a few realistic scenarios.

Here's a simplified comparison using illustrative figures. Your actual premiums, deductibles, and out-of-pocket maximum depend on your plan, location, age, and the current plan year, so treat the dollar amounts as directional, not a quote.

If you go uninsured:

Nothing happens: You keep whatever you would have spent on premiums. Call it a clean win for that period, financially speaking.
One moderate event (a broken bone, an ER visit that needs a workup): You're out several thousand dollars, paid in full, at uninsured billing rates, with no cap.
One major event (a surgery, a serious diagnosis, a bad accident): You're out tens of thousands of dollars or more, with no cap, and a real chance of medical debt that affects your credit and finances for years.

If you have the cheapest compliant plan (Catastrophic or Bronze), which some low-income enrollees may still get at a $0 premium:

Nothing happens: You paid your premium (a modest monthly amount for most, though some low-income enrollees may pay $0) and got free preventive care and mental health access you didn't have to think about.
One moderate event: You pay toward your deductible and coinsurance, but for covered in-network care you won't pay more than your plan's out-of-pocket maximum for the year. You know in advance what the worst case costs you.
One major event: Same principle. Your spending on covered, in-network care for the year is capped at your plan's out-of-pocket maximum ($10,600 in 2026; $12,000 in 2027, individual). Premiums, out-of-network care, services the plan doesn't cover, and balance bills don't count toward the cap. This is the scenario where the math tips hardest in favor of having coverage.

The expected-value takeaway: If you assume nothing will ever go wrong, going uninsured wins by the amount of the premium. But moderate and major medical events are common enough among healthy young adults, not rare edge cases, that the expected cost of going uninsured over several years is generally higher than the cost of the cheapest available coverage, especially once you account for subsidies, which for some low-income enrollees can still bring premiums to $0 or close to it (less common since the enhanced credits expired at the end of 2025). The math isn't about whether something will happen to you specifically. It's about what happens to your finances in the years it does.

Your action plan

Check your Medicaid eligibility first. Income thresholds vary by state; don't assume you're over the line without checking.
Check whether you qualify for a $0 or low-premium Marketplace plan. Subsidy levels change year to year.
If you don't qualify for either, compare Catastrophic, Bronze, and short-term options based on your age, health history, and state's rules.
Confirm your state's individual mandate status if you live in California, Massachusetts, New Jersey, Rhode Island, or DC (Vermont requires coverage but attaches no penalty).
Enroll during Open Enrollment. For 2027 coverage it runs November 1 through January 15 on HealthCare.gov; enroll by December 15 for coverage starting January 1. State marketplaces may differ. Or check whether a qualifying life event gives you a Special Enrollment Period right now; if so, keep proof of your life event, because HealthCare.gov verifies most special enrollment sign-ups.
Once covered, use your free preventive care. It's already included in your premium.
