What Is Major Medical Insurance? How to Tell What You Are Buying
By Frank Caballero, licensed health insurance broker (NPN 21032307) · Updated
Major medical is one of the most used phrases in health insurance and one of the least explained. Ads use it loosely, and some products that look like health insurance on a quote screen are something else entirely. Here is what the term means, what sits outside it, and how I check what a plan really is before anyone signs.
Private health insurance
Most people I help end up on a private plan, not a Marketplace plan. Private, medically underwritten health insurance is priced on your age, zip code and health instead of your income, so a strong year never raises your premium and there is no tax credit to pay back in April.
Why people leave the Marketplace
- Premiums keep climbing. Marketplace premiums are rising again for 2027.
- The subsidy cliff. Above 400 percent of the poverty level ($63,840 for one person, $132,000 for a family of four) you pay full price.
- Surprise tax bills. Underestimate your income and you repay the tax credit in April.
- Narrow networks. Many plans are local HMOs or EPOs that need referrals and cover little outside the area.
- High out-of-pocket costs. 2027 out-of-pocket maximums reach $12,000 per person and $24,000 per family.
- One window a year. Outside open enrollment you need a qualifying life event to enroll or switch.
What a private plan does differently
- Start any month. If approved, coverage can begin the first of next month, with no wait for open enrollment.
- Networks that travel. Many private plans use national PPO networks, which can give you in-network doctors outside your home state too. Networks vary by plan.
- Can cost less than full-price Marketplace plans for some healthy applicants above the subsidy line.
- Accident coverage the Marketplace does not offer. A private plan can be paired with accident coverage, a separate policy. What it includes varies by plan.
- Approval is based on health. You answer health questions, and acceptance is not guaranteed.
With a significant health condition, or income low enough for a large tax credit, a Marketplace plan can be the better fit, and I will tell you if it is. Either way you see both side by side.
Private plans are not ACA Marketplace plans. Benefits, exclusions and pre-existing condition rules differ by plan and by state, so review the plan details before you enroll.

What major medical means
Major medical insurance is comprehensive coverage for both the big events and the everyday: doctor visits, hospital stays, surgery, emergency care, prescriptions, lab work and imaging. It pays a share of the actual bill once you meet a deductible, and it limits what you pay in a year with an out-of-pocket maximum. When something serious happens, major medical coverage is what keeps a hospital bill from becoming a financial crisis.
Today the term usually covers:
- ACA-compliant individual plans, sold on HealthCare.gov, state exchanges or directly by insurers. They must cover the ten essential health benefits and cannot deny you for health reasons. The Marketplace coverage guide explains what they include.
- Employer group plans, including COBRA continuation of one.
- Some private, medically underwritten plans that are designed to work like comprehensive coverage. Approval depends on your health answers, and benefits vary by plan.
What major medical is not
Plenty of products are sold next to major medical, or instead of it. Each has a job, but none is a substitute for comprehensive coverage on its own.
- Short-term health plans. Temporary coverage for a gap. They are usually medically underwritten, generally exclude pre-existing conditions, often have a maximum benefit, and do not have to cover the essential health benefits. The short-term vs ACA guide compares the two.
- Fixed indemnity plans. These pay a set dollar amount for a covered event, such as a fixed sum per day in the hospital or per office visit, regardless of what the provider actually charges. If the bill is bigger than the benefit, you owe the rest.
- Hospital indemnity, critical illness and accident plans. These are separate policies tied to specific events, such as a hospital admission, a covered diagnosis or an injury. What they include varies by plan. They can sit alongside a high-deductible plan, not in place of one.
- Limited benefit plans. These cover a short list of services, or cap each benefit at a modest amount.
- Discount medical cards. Not insurance. They offer reduced prices at participating providers and pay nothing toward the bill.
- Health care sharing ministries. Not insurance either. Members share each other's medical bills under the group's guidelines, with no legal guarantee of payment. See the health sharing guide.
Why the difference matters
Picture a three-day hospital stay with surgery, billed at tens of thousands of dollars. On a major medical plan, you pay your deductible and coinsurance up to the out-of-pocket maximum, and the plan pays the rest of the covered, in-network amount. On a fixed indemnity plan that pays a set amount per hospital day and a set amount for the procedure, you receive those amounts and owe the hospital everything else. The indemnity plan's premium may be lower, but the protection is not in the same category.
The same logic applies to prescriptions, cancer treatment, a premature birth or a long rehab stay. Those are the expensive moments that comprehensive coverage exists for, and they are exactly where limited products tend to run out.
How to tell what you are buying
You do not have to read every page of a policy to know what it is. Look for these:
- How it pays. A percentage of the bill after a deductible points to major medical. Fixed dollar amounts per day, visit or event point to indemnity coverage.
- An out-of-pocket maximum. Comprehensive plans have one. If you cannot find it, ask.
- Maximum benefits. Annual, lifetime or per-condition caps on what the plan pays are a sign of limited or short-term coverage.
- Pre-existing condition language. Look for look-back periods, exclusions and waiting periods.
- The core benefits. Check maternity, mental health, prescriptions and rehabilitation. Gaps there are common outside ACA plans.
- Prescription coverage. Is there a real drug list, or only a discount?
- The network. Are providers contracted to accept the plan's payment, or is it only access to discounted prices?
- The term. Does it renew year after year, or end on a fixed date?
- The disclosures. Limited and short-term products often include a notice saying they are not comprehensive coverage. Read the first page of the application and the policy, not just the brochure.
- A Summary of Benefits and Coverage. ACA plans and employer plans must provide this standard document. If a product cannot give you one, ask why.
Where private plans fit
Private, medically underwritten plans are their own category, and they vary widely. Some are built to work much like comprehensive major medical coverage; others pay set amounts for some services, or combine different types of coverage in one package. Approval depends on your health answers, pre-existing conditions may be excluded or lead to a decline, and benefits vary by plan.
That is not a reason to avoid them. For a healthy household above the subsidy line, a private plan can be the best value available. It is a reason to know exactly how the plan pays before you apply, and that is the first thing I go over on a call. The underwriting guide explains how approval works.
Where Marketplace plans fit
Every Marketplace plan is major medical by definition. It accepts everyone, covers pre-existing conditions and has no annual or lifetime dollar limits on essential benefits. The trade-offs are full price above the subsidy line, a once-a-year enrollment window and, in many areas including much of Florida, HMO or EPO networks tied to a local hospital system.
Is a limited plan ever the right call?
Sometimes. A short-term plan can bridge a gap with a known end date. A hospital indemnity or critical illness plan can add cash on top of a high-deductible plan. The problem is when a limited product is sold, or bought, as if it were the main coverage. If a plan sounds inexpensive for everything it seems to promise, read how it pays.
There is no federal penalty for going without comprehensive coverage, but a few states, along with Washington, D.C., have their own coverage requirement. Florida does not. Either way, the real risk of going without major medical is the bill, not the penalty.
