Best Health Insurance Companies | man balancing companies

The 12 top health insurance companies, reviewed!

There’s a difference between health insurance companies and health insurance plans. When you sign up for health insurance, you’re actually joining one of many plans that are sold by a health insurance company. Luckily, the best health insurers have different plans to suit all sorts of folks.

The top 12 health insurance companies make up just over 50 percent of revenue in the American health insurance market. They collect roughly $515 billion in premiums – the monthly price you pay to stay on a plan – each year. You can decide which health insurer is best.

Another 113 companies split most of the remaining American health insurance market.

Each of these companies will offer multiple different plans. They generally have to offer different plans in different states. They’ll even have doctors that participate in some of their plans but not others.

You can compare health insurance plans by looking at several different features – including:

  • Coinsurance – the percentage of care that you pay for on your own.
  • Deductibles – how much you contribute entirely on your own before your insurance begins to pay for care.
  • Out-of-pocket maximum – once you spend this amount, your plan pays 100 percent of costs.

That’s just a sample of how plans differ from one another. For a more meaningful comparison, re-start your search by comparing individual health insurance plans.
