The average American family spent $24,000 on health insurance in 2025 — that is premiums plus out-of-pocket costs combined, according to the Kaiser Family Foundation. For a single individual, the figure was closer to $8,500. Those numbers make health insurance one of the largest expenses in most household budgets, yet the majority of people spend less time choosing their health plan than they spend picking a new phone.
Here is what makes this so costly: picking the wrong plan type can easily waste $2,000-$5,000 per year. A healthy 28-year-old on a PPO plan might be paying $200/month more in premiums than necessary when an HDHP with an HSA would cover them just as well and provide a tax-advantaged savings account on top. A family with a member who has a chronic condition might choose an HDHP to save on premiums, then get crushed by $8,000 in out-of-pocket costs before the deductible kicks in.
This guide breaks down every major plan type, explains the jargon that insurers rely on to confuse you, and gives you a framework to make the right choice during open enrollment.
Key Takeaways
- HMO plans have lower premiums and require referrals and in-network care, making them best for people who do not mind a gatekeeper and want predictable costs.
- PPO plans cost more in premiums but offer the flexibility to see any provider without referrals, including out-of-network doctors at higher cost-sharing.
- HDHP plans paired with an HSA offer the lowest premiums and a triple tax-advantaged savings account, making them ideal for healthy individuals who can cover the higher deductible.
- The “cheapest” plan is not always the best value — total annual cost (premiums plus expected out-of-pocket spending) is what matters.
- An HSA is the most tax-advantaged account in the U.S. tax code, combining tax-deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses.
Health Insurance Jargon, Translated
Before comparing plans, you need to understand the terminology. Insurers weaponize jargon to make comparison shopping harder, so here is a plain-language glossary of the terms that actually matter.
Premium: The amount you pay monthly to have the insurance policy, regardless of whether you use any medical services. Think of it as a subscription fee.
Deductible: The amount you must pay out of pocket before insurance begins covering costs. A $2,000 deductible means you pay the first $2,000 of medical bills yourself each year. Preventive care (annual checkups, vaccinations, screenings) is typically covered before you meet the deductible under all ACA-compliant plans.
Copay: A fixed dollar amount you pay for a specific service. “$30 copay for a primary care visit” means you pay $30 and the insurer pays the rest, regardless of the visit’s total cost.
Coinsurance: A percentage of costs you pay after meeting your deductible. “20% coinsurance” means you pay 20% of covered services and the insurer pays 80%.
Out-of-pocket maximum: The absolute most you will pay in a year for covered services. Once you hit this number, the insurer pays 100% of covered costs for the rest of the year. For 2026, the ACA caps this at $9,450 for individual plans and $18,900 for family plans.
Network: The group of doctors, hospitals, and pharmacies that have contracted with your insurer for negotiated rates. Using in-network providers almost always costs significantly less than going out-of-network.
HMO: The Gatekeeper Model
A Health Maintenance Organization (HMO) plan requires you to choose a primary care physician (PCP) who acts as your gatekeeper to the healthcare system. Need to see a dermatologist? Your PCP must provide a referral first. Want to see an orthopedic surgeon for your knee? Referral. Every specialist visit routes through your PCP.
HMO plans almost exclusively cover in-network care. If you see an out-of-network provider without emergency circumstances, you pay the entire bill yourself.
Typical HMO costs:
- Monthly premiums: Lower than PPO (often 15-25% less)
- Deductibles: Low or none for in-network services
- Copays: Fixed amounts ($20-$40 for PCP, $40-$75 for specialists)
- Out-of-pocket max: $5,000-$8,000 individual
Best for: People who are comfortable with a single PCP coordinating their care, who live in an area with a strong HMO network (Kaiser Permanente regions, for example), and who prioritize lower premiums and predictable costs over flexibility.
Worst for: People who want to self-refer to specialists, who travel frequently and need coverage in multiple regions, or who have existing relationships with out-of-network doctors they want to keep.
PPO: Maximum Flexibility, Maximum Cost
A Preferred Provider Organization (PPO) plan gives you the freedom to see any provider — in-network or out-of-network — without referrals. You can book an appointment with any specialist directly. You can see a doctor in another state without worrying about network restrictions.
The tradeoff is cost. PPO premiums are the highest of any standard plan type. Out-of-network care is covered but at a significantly higher cost-sharing rate.
Typical PPO costs:
- Monthly premiums: Highest (often $100-$250/month more than HMO for comparable coverage)
- Deductibles: Moderate ($500-$2,000 in-network)
- Copays/coinsurance: Varies by service; out-of-network typically 40-50% coinsurance
- Out-of-pocket max: $6,000-$9,000 individual in-network; $15,000+ out-of-network
Best for: People who want flexibility, who see multiple specialists, who travel or live in areas with limited in-network options, or who have a specific doctor they refuse to give up.
Worst for: Healthy individuals who rarely use medical services beyond preventive care — they are paying premium prices for flexibility they do not use.
HDHP: Low Premiums, High Deductible, and the HSA Superpower
A High Deductible Health Plan (HDHP) has lower monthly premiums but requires you to pay a higher deductible before insurance kicks in. For 2026, the IRS defines an HDHP as a plan with a deductible of at least $1,650 for individual coverage or $3,300 for family coverage.
The real appeal of an HDHP is not the low premiums — it is the Health Savings Account (HSA) that becomes available when you enroll in one.
Typical HDHP costs:
- Monthly premiums: Lowest (often $50-$150/month less than a PPO)
- Deductibles: High ($1,650-$5,000 individual, $3,300-$10,000 family)
- Coinsurance: Typically 20-30% after deductible
- Out-of-pocket max: $8,050 individual, $16,100 family (2026 IRS limits)
The HSA: The Best Account in the Tax Code
An HSA is a savings account available exclusively to HDHP enrollees that provides a triple tax advantage no other account matches:
- Tax-deductible contributions. Every dollar you put in reduces your taxable income. If you contribute the 2026 maximum of $4,300 (individual) or $8,550 (family) and you are in the 22% bracket, you save $946 or $1,881 in federal taxes.
- Tax-free growth. Money in the HSA can be invested in mutual funds and ETFs, just like a 401(k) or IRA. All growth — dividends, interest, capital gains — is completely tax-free.
- Tax-free withdrawals for medical expenses. When you use HSA funds for qualified medical expenses (doctor visits, prescriptions, dental, vision, and more), you pay no taxes on the withdrawal.
No other account in the U.S. tax code offers tax benefits at all three stages. A Traditional IRA gives you a deduction going in but taxes withdrawals. A Roth IRA offers tax-free withdrawals but no deduction going in. The HSA does both and adds tax-free growth in the middle.
The power move: if you can afford to pay medical expenses out of pocket, max out your HSA contributions and let the money invest and grow. There is no requirement to use HSA funds in the year they are contributed. You can invest your HSA for decades, let it compound, and withdraw tax-free in retirement for medical expenses (or for any purpose after age 65, at which point it functions like a Traditional IRA with ordinary income taxes but no penalty).
Best for: Healthy individuals and families who can absorb the higher deductible, who want to maximize tax-advantaged savings, and who can treat the HSA as a long-term investment account.
Worst for: People with chronic conditions requiring frequent medical care, who would hit the deductible early and often, making the premium savings irrelevant relative to the high out-of-pocket costs.
How to Choose: A Decision Framework
Forget comparing plans in the abstract. The right plan depends on your expected healthcare usage. Here is a practical decision framework.
Step 1: Estimate Your Annual Healthcare Spending
Look at last year’s medical expenses. Include doctor visits, prescriptions, lab work, imaging, therapy, and any procedures. If you are generally healthy and only see a doctor for an annual physical, your expected spending might be $500-$1,000. If you have a chronic condition, regular specialist visits, or expensive medications, it might be $5,000-$15,000.
Step 2: Calculate Total Annual Cost for Each Available Plan
Total annual cost = (monthly premium times 12) + expected out-of-pocket costs.
For each plan available to you, estimate the out-of-pocket costs based on your expected usage. This is where most people make the critical mistake: they compare premiums alone and ignore total cost.
Example — healthy individual, expected $800 in medical expenses:
- HMO: $350/month premium times 12 = $4,200 + $200 in copays = $4,400 total
- PPO: $500/month premium times 12 = $6,000 + $200 in copays = $6,200 total
- HDHP: $250/month premium times 12 = $3,000 + $800 (paid toward deductible) = $3,800 total, minus $946 in HSA tax savings = $2,854 effective total
The HDHP wins by over $1,500 for a healthy person. That gap widens even further if you invest the HSA contributions.
Example — family with chronic condition, expected $12,000 in medical expenses:
- HMO: $900/month times 12 = $10,800 + $2,000 in copays/coinsurance = $12,800 total
- PPO: $1,200/month times 12 = $14,400 + $2,500 in copays/coinsurance = $16,900 total
- HDHP: $650/month times 12 = $7,800 + $8,000 (deductible) + $1,200 (coinsurance) = $17,000 total, minus $1,881 HSA tax savings = $15,119 effective total
The HMO wins for a family with high medical usage, saving over $2,000 annually compared to the PPO.
Step 3: Factor in Non-Financial Considerations
Cost is not everything. Ask yourself:
- Do I have a preferred doctor who is only in certain networks?
- Do I need regular specialist access without referral hassles?
- Am I comfortable managing a high deductible if an unexpected medical event occurs?
- Do I want the long-term investment benefits of an HSA?
Open Enrollment Tips
Open enrollment is typically in the fall (November-December for ACA marketplace plans, varies by employer). This is your annual chance to switch plans without a qualifying life event.
Review every year. Plans change annually — premiums increase, networks shrink, formularies drop medications. Last year’s best choice may not be this year’s.
Check the formulary. If you take prescription medications, verify they are covered on the plan’s drug formulary and at what tier. A drug moving from Tier 2 to Tier 3 can double your copay.
Verify your doctors. Confirm your preferred providers are still in-network before you enroll. Networks change constantly.
Max your HSA if eligible. If you choose an HDHP, set up automatic contributions to your HSA from the start. Many employers also contribute to your HSA — this is free money, much like a 401(k) match.
Common Mistakes
Choosing the lowest premium without calculating total cost. A $200/month HDHP premium looks great until you have a $10,000 medical event and owe the full deductible. The cheapest premium and the cheapest total cost are often different plans.
Not using preventive care. All ACA-compliant plans cover preventive care at no cost — annual physicals, vaccinations, cancer screenings, blood pressure checks. Skipping these saves nothing and catches problems late when they are more expensive (and dangerous) to treat.
Leaving HSA money in cash. Many HSA providers default to a savings account earning minimal interest. If you do not need the funds for near-term medical expenses, invest them in index funds for long-term growth. Over 20-30 years, the difference between cash and invested HSA funds can be $50,000 or more.
Ignoring out-of-network costs. Emergency care is covered regardless of network under the No Surprises Act. But non-emergency out-of-network care — choosing to see an out-of-network surgeon, for example — can result in bills that count toward a separate, much higher out-of-pocket maximum or are not covered at all.

Frequently Asked Questions
Can I switch from an HMO to a PPO mid-year?
Generally, no. You can only change health insurance plans during open enrollment or if you experience a qualifying life event (marriage, birth of a child, job loss, moving to a new coverage area). Plan your choice carefully during enrollment season because you are locked in for the year.
Is an HSA the same as an FSA?
No. A Flexible Spending Account (FSA) is offered through employers, has a lower contribution limit ($3,300 in 2026), and operates on a “use it or lose it” basis — unspent funds at year-end are forfeited (some plans allow a $640 rollover). An HSA has higher limits, rolls over indefinitely, is portable if you change jobs, and can be invested for growth. The HSA is superior in almost every way but requires HDHP enrollment.
What happens to my HSA if I switch to a non-HDHP plan?
You keep the money. You can still use existing HSA funds for medical expenses tax-free. You just cannot make new contributions while enrolled in a non-HDHP plan. The account stays open and the investments continue to grow.
How do I know if my medications are covered?
Every insurer publishes a formulary — a list of covered drugs organized by tier. Tier 1 (generics) has the lowest copays, Tier 2 (preferred brands) is moderate, and Tier 3-4 (non-preferred/specialty) are the most expensive. Search “[insurer name] formulary” or call the insurer’s member services line. If a critical medication is not covered or is on an expensive tier, that plan may not be right for you regardless of its premium.
Does health insurance cover mental health services?
Yes. Under the Mental Health Parity and Addiction Equity Act, health insurers must cover mental health and substance use disorder services at the same level as physical health services. Copays, deductibles, and visit limits for therapy and psychiatric care cannot be more restrictive than those for medical/surgical care. However, finding in-network mental health providers can be challenging due to provider shortages, so verify network availability before enrolling.
