What Is Private Health Insurance?
*Updated December 29th, 2025
Private health insurance is a major part of the insurance system in the United States, providing health coverage for more than half the population. If you’re trying to understand how it compares to public health programs and how a health insurance plan fits your needs, this guide breaks it all down.
You’ll learn what private health insurance is, how public health insurance differs, how health insurance works, and what to consider when picking the right health plan.
Understanding Private Health Insurance
Private health insurance refers to health insurance coverage offered by private insurance companies rather than government insurance programs like Medicare, Medicaid, the Children’s Health Insurance Program (CHIP), or the State Children’s Health Insurance Program. In other words, private health insurance is managed and sold by health insurers that operate in the private market.
A private health insurance plan can be purchased in two main ways:
-
As an individual plan through a health insurance marketplace (also called a health insurance exchange) or directly from an insurance company
This is one of the most common types of health insurance coverage in the U.S., and it plays a key role alongside public health insurance programs.
Employer-Sponsored Health Insurance
Most Americans get private health insurance through employer-sponsored health coverage. With health insurance from an employer, the employer typically pays part of the insurance premiums, helping employees access lower health insurance costs.
Eligibility depends on employment status, and many plans allow you to add dependents. For many households, employer-sponsored health is the most affordable way to access a strong health insurance plan.
Individual and Family Plans
If you don’t have employer-sponsored health, you can buy private coverage on your own through the health insurance marketplace or a private insurer.
ACA marketplace plans may qualify you for premium tax credits, which help reduce your monthly premium. These plans are divided into metal tiers (Bronze, Silver, Gold, Platinum) based on cost-sharing and expected out-of-pocket spending.
This route provides multiple health insurance options, especially for the self-employed, freelancers, early retirees, or anyone between jobs.Supplemental and Short-Term Plans
Some people add extra coverage or fill gaps with additional plans:
-
Dental and vision insurance (often offered as supplemental policies)
-
Short-term health insurance (temporary coverage, usually with limited benefits and fewer protections)
While short-term health insurance can help with brief transitions, it generally does not include all essential health benefits and may differ from regulated private health insurance that meets ACA standards.
How Health Insurance Works
To choose the right coverage, it helps to understand how health insurance works in practice. Whether you’re evaluating public or private options, most plans involve a mix of monthly costs and out-of-pocket expenses when you use care.
How Private Health Insurance Works
Here’s how private health insurance work for most people:
Premiums
A premium is what you pay each month to keep your health insurance coverage active. Health insurance premiums vary by plan type, age, location, and coverage level. Higher premiums often mean lower out-of-pocket costs, but not always.
Deductibles, Copays, and Coinsurance
In addition to premiums, most private plans include cost-sharing:
-
Deductible: what you pay before your plan pays for most services
-
Copayments: flat fees for certain visits or prescriptions
-
Coinsurance: a percentage split between you and the insurer after you meet the deductible
These factors directly shape your total health care costs.
Networks
Many private health plans use provider networks to control costs:
-
In-network care is usually cheaper
-
Out-of-network care can cost more—or may not be covered
Knowing your network is key when comparing health insurance companies.
Public Health Insurance and Public Health Programs
Public health insurance refers to government-funded or government-run health insurance program options such as Medicare, Medicaid, and CHIP. In general, public health insurance is funded through taxpayer dollars and administered by federal and state agencies, often under the oversight of Health and Human Services.
Some people also receive care through specific public systems like the Indian Health Service, depending on eligibility.
These public health insurance options can provide crucial coverage, but plan rules, provider access, and benefits can differ from private plans.
Public and Private Health Insurance: What’s the Difference?
The biggest distinction between public and private health insurance comes down to funding, eligibility, and administration.
-
Public insurance is generally tied to age, income, disability status, or other eligibility rules.
-
Private health insurance is purchased through employers or by individuals, and is run by insurance companies and other private entities.
In many cases, people combine coverage types—using a public program as a base and adding private coverage to fill gaps.
Benefits of Private Health Insurance
There are several benefits of private health insurance, especially for people who want flexibility and broader choices.
Comprehensive Coverage
Most ACA-compliant private plans include essential health benefits and cover a wide range of health care services, including preventive care, hospitalization, prescription drugs, and more.
Choice of Providers
Private coverage often includes larger networks, giving you more ability to choose specialists, hospitals, and providers you prefer.
Faster Access to Care
Compared to some public programs, private plans may offer quicker access to non-emergency services and specialist appointments.
Customizable Insurance Options
Private plans offer a range of configurations—HMOs, PPOs, EPOs, and HDHPs—letting you tailor your health plan to your budget and healthcare usage.
Types of Private Health Insurance
If you’re comparing types of private health insurance, these are the most common:
-
Employer-sponsored health insurance
-
Individual ACA marketplace plans
-
Plans purchased directly from a health insurance provider
-
Supplemental plans like dental and vision
-
Limited-duration options like short-term health insurance
Understanding these different types of private health plans can help you match coverage to your needs.
Who Should Consider Getting Private Health Insurance?
You may want to get private health insurance if you:
-
Don’t have employer coverage
-
Are self-employed or freelancing
-
Want more plan flexibility than certain public programs offer
-
Need coverage not provided through public health insurance programs
If you’re weighing public or private options, your eligibility, budget, and provider preferences will usually drive the decision.
Common Misconceptions About Private Health Insurance
Myth 1: Private Insurance Is Always Expensive
Many people assume private health insurance costs are always high, but premium tax credits can lower premiums for ACA marketplace plans. Employer contributions can also reduce costs significantly.
Myth 2: Private Insurance Doesn’t Cover Pre-Existing Conditions
For ACA-compliant plans, insurers can’t deny coverage or charge more due to medical history.
Myth 3: Private Plans Always Have High Out-of-Pocket Costs
Plan design varies widely. Some higher-premium plans offer lower deductibles and lower out-of-pocket spending overall.
How to Choose the Right Private Health Insurance Plan
To pick the best private health insurance plan, compare:
-
Monthly premium
-
Deductible and copays
-
Network size and preferred doctors
-
Prescription coverage
-
Total annual cost (including out-of-pocket maximum)
Use marketplace tools to compare health insurance options side-by-side, and consider whether you qualify for premium tax credits.
