Most explanations of private health insurance are written either by someone selling it or by someone who thinks it shouldn't exist. This one tries to be neither. Here is what it is, how it works, and the situations where it is genuinely the wrong choice.
What 'private' actually means here
Private health insurance, in this context, means an individual medical plan sold outside the ACA Health Insurance Marketplace by a nationally recognized carrier. It is real insurance: a regulated contract with a licensed insurer, overseen by your state's department of insurance.
It is not a health sharing ministry, not short-term medical, and not a discount card. Those are different products with different rules, and they get conflated constantly — usually by people who want the comparison to be confusing.
The one difference that drives everything else
Marketplace plans are guaranteed issue. The carrier must accept you regardless of health history, and in exchange everyone's premium reflects the cost of covering everyone.
Private plans are medically underwritten. The carrier asks about your health and can decline. That is the trade: because the pool is healthier, premiums are lower — often dramatically. Every other difference on this page follows from that single fact.
What it typically costs
An unsubsidized bronze marketplace premium of around $750 a month with a $5,000-plus deductible is common. A private PPO for a healthy applicant in the same situation often lands near $300 with a far lower deductible.
Those figures aren't your rate. What you pay depends on your age, your state, your health history, and the plan you pick — and only a licensed advisor can confirm it.
What underwriting is actually like
It is a health questionnaire, sometimes followed by a prescription-history check. There is no physical exam on most plans.
Conditions that are well-controlled are frequently fine. Conditions in active treatment are where declines happen. The productive question is never 'will I be approved' in the abstract — it is 'which carriers will take this specific history', which is the thing an advisor actually knows.
Who should not buy one
There are four clear cases, and no honest guide can skip them:
- You qualify for Medicaid. Take it. It is cheaper and usually better.
- You receive a substantial ACA premium tax credit. The subsidized plan almost certainly wins.
- Your employer pays most of your premium. Stay on the group plan.
- You are 65 or Medicare-eligible. That is a separate system with separate rules.
How to compare two plans properly
Premium is the number everyone looks at and the least useful one on its own. Compare the four together: monthly premium, deductible, out-of-pocket maximum, and whether your doctors are in network.
Then read the exclusions. Every plan has them; the question is whether they touch anything you actually use.
