Health Insurance
Private Health Insurance
A term that covers several different kinds of product — including comprehensive plans and policies that are not comprehensive at all.
Private Health Insurance at a glance
- Not one product
- The phrase describes who sells the coverage, not what the coverage does or which rules apply to it.
- It can be comprehensive
- ACA-compliant major medical plans are sold by private insurers.
- It can be something else
- Limited-benefit products are also private insurance, and they work differently.
- The terms decide
- What a policy covers is a question about that policy, not about the category.
Two different kinds of health coverage
Comprehensive coverage
Major medical coverage
Pays a share of your covered medical expenses, according to the plan's cost-sharing rules.
- Covers the essential health benefit categories
- Cannot refuse you or charge more for a pre-existing condition
- Has a yearly limit on in-network cost sharing for covered essential health benefits
ACA-compliant coverage is sold two ways
Marketplace plans
Bought through the Health Insurance Marketplace, which is the only place premium tax credits and cost-sharing reductions can be applied.
Off-Marketplace ACA-compliant plans
Bought directly from an insurer or through an agent. Subject to the same coverage rules, without the Marketplace financial assistance.
These are different categories of product, not two grades of the same one. A limited-benefit policy is not a substitute for comprehensive coverage, and some people hold one alongside comprehensive coverage rather than instead of it.
Limited or supplemental coverage
Limited-benefit products
Pays set benefits according to the policy's own schedule or covered-event structure.
- Pays set benefits defined by the policy
- Benefits are paid regardless of what the care actually cost
- Coverage, exclusions and limits are specific to each policy
Fixed indemnity is the most common example. Others exist, and what any of them covers depends on the individual policy — which is why the terms matter more here than the category name.
What is private health insurance?
"Private health insurance" describes coverage sold by a private insurer rather than provided through a government program such as Medicaid or Medicare. That is all the phrase establishes. It says nothing about what the policy covers, how it pays, which rules it follows, or how much it costs.
That matters because the phrase is used for two quite different things. Comprehensive major medical plans that meet the ACA's requirements are sold by private insurers — through the Marketplace and, in many places, directly. So are limited-benefit products such as fixed indemnity policies, which pay set benefits under their own terms and are not a substitute for comprehensive coverage. Both are private insurance. Only one of them is comprehensive major medical coverage.
What the term can mean
Two broad groups, and the difference between them is the most consequential thing about any offer you are looking at.
- ACA-compliant private major medical coverageSold through the Marketplace, or in many places directly from an insurer or through an agent. The same coverage rules apply either way; only the Marketplace can apply premium tax credits and cost-sharing reductions.
- Other private insurance productsFixed indemnity and other limited-benefit structures, sold privately and governed by their own policy terms. What each covers, excludes and limits is specific to the policy.
What it does not automatically mean
Each of these is true of some private policies and false of others. None of them follows from the word "private", and an offer that implies otherwise is describing a particular product rather than the category.
- Not automatically medically underwrittenACA-compliant plans cannot use your health against you. Whether any particular non-ACA policy asks health questions depends on that policy and on state rules.
- Not automatically cheaperA lower premium can reflect less coverage rather than a better price, and a plan bought outside the Marketplace cannot carry the Marketplace's financial assistance.
- Not automatically a broader networkNetworks are set by the individual plan. Some private plans have narrow networks and some limited-benefit policies have no network arrangement at all.
- Not automatically a PPOPlan structure — HMO, PPO, EPO and others — is a feature of the specific plan, and plans of every structure are sold both on and off the Marketplace.
- Not automatically without a deductibleCost sharing is whatever the policy says it is.
- Not automatically outside the ACA's rulesMany privately sold plans are ACA-compliant. Whether a specific policy is comprehensive major medical coverage is a question to ask directly, in writing.
Questions that establish what you are being offered
Worth asking in writing, and worth asking before price. Each is phrased so that it does not assume its own answer.
- Is this comprehensive major medical coverage?
- Is this policy ACA-compliant?
- How does this policy treat pre-existing conditions, and how does that compare with an ACA-compliant plan?
- What provider network applies, and what happens if I use a provider outside it?
- How are prescriptions covered, and is there a formulary I can read?
- Is there a deductible, and which services are subject to it?
- What are the copays and coinsurance, by service?
- Is there a yearly limit on what I pay out of pocket, and what does it exclude?
- Are there benefit limits — per service, per day, per year or per lifetime?
- What is excluded?
- Is coverage medically underwritten, and can the policy be rescinded or rated after issue?
- Can the policy be renewed, and on what terms?
- What would this policy pay if I had a major hospitalization or an expensive course of treatment?
Common misconceptions
Each of these is repeated often enough to be worth answering directly.
Often heard
Private health insurance means not ACA-compliant.In practice: Most comprehensive individual coverage in the United States is sold by private insurers, including every plan in the Marketplace. Whether a specific policy is ACA-compliant is a property of that policy.
Often heard
Going private always saves money.In practice: It depends entirely on the policy, on what it covers, and on whether Marketplace financial assistance would have been available to you. A lower premium can mean a lower level of coverage.
Often heard
Private plans always have bigger networks.In practice: Networks are set plan by plan. The only way to know is to check your own providers against the specific plan's current directory.
