The best private health insurance companies

Kaiser Permanente tops quality rankings, with NCQA scores near 4.5 out of 5, well above the national average, and an integrated model where doctors, hospitals, and pharmacy work as one system. That coordination suits members who want preventive care and predictable costs, with strong digital tools for appointments, records, and messaging.
The catch is geography: Kaiser serves 8 states plus D.C., including California, Colorado, Georgia, Hawaii, Maryland, Oregon, Virginia, and Washington, so most Americans cannot buy it. Members must generally use Kaiser facilities. For people in Kaiser states, it is clearly the best quality pick, since its integrated model and NCQA scores lead the industry.
What we like- Highest NCQA ratings near 4.5
- Integrated doctors, hospitals, and pharmacy
- Strong preventive care
Watch out for- Available in 8 states plus D.C. only
- Must use Kaiser facilities
- Smaller footprint

How we chose
We compared NCQA quality ratings, AM Best financial strength ratings, NAIC complaint levels, network size, plan variety, and digital experience. We also weighed medical loss ratios, since a higher ratio means more of your premium goes toward care rather than administration and profit. Companies with 4 plus NCQA ratings scored highest on quality, while companies with below-average complaint levels scored higher on service. We favored insurers with broad state availability and noted where availability is limited. We did not enroll in any plan hands-on, and premiums vary by state and plan.
Buying guide: what to check before you enroll
Start with your doctors, since the best plan is worthless if your doctors are out of network. Check the drug formulary for your prescriptions, since pharmacy costs vary sharply by plan. Compare total costs, not premiums alone: add the deductible, copays, coinsurance, and out-of-pocket maximum, since a low premium with a high deductible can cost more for people who use care often. Check NCQA ratings and complaint levels for your specific plan, not just the company, since ratings vary by plan. Confirm whether your state marketplace offers subsidies, since ACA subsidies can cut premiums sharply for eligible buyers. Finally, get a quote for your ZIP code, age, and household size before you decide, since national averages hide large state differences. Talk to a licensed broker if the choice is unclear, since brokers can compare plans across insurers at no direct cost to you, and they know which local plans have the strongest networks in your area. This article is not financial or medical advice, and plan details change yearly, so verify benefits on the insurer site before enrolling.
Frequently asked questions
What is the best private health insurance company?
Kaiser Permanente ranks highest on quality where available, while Blue Cross Blue Shield offers the widest network and UnitedHealthcare offers the largest national footprint. The best choice depends on your state and doctors.
How much does private health insurance cost?
Premiums vary sharply by state, age, household size, and plan metal tier, so no single figure applies. Get a quote for your ZIP code and compare total costs, including deductibles and out-of-pocket maximums.
What is an NCQA rating?
The National Committee for Quality Assurance rates health plans from 1 to 5 stars on clinical quality, patient experience, and preventive care. A rating of 4 or higher is exceptional.

People who use care rarely may save with a low premium and high deductible, while people who use care often usually save with a higher premium and lower deductible. Compare total costs for your expected use.

Generally, you need a qualifying life event, such as losing job coverage or moving, to buy outside open enrollment, though Medicaid and some state programs accept enrollment year-round. Check your state marketplace rules.
