Health Insurance is an extremely competitive business however unlike auto insurance (where the top providers have secured almost 70% of the market) even the most well-known health insurance companies only have a small percentage of the market.
In a report published by the NAIC (National Association of Insurers Commissioners) the top 10 Accident and Health Insurance Companies in the USA for 2010 are listed below.
These numbers only represent a national market share. In many states some companies have significantly more market share and some have little or no presence. You can view the top health insurance companies by state and learn more about your health insurance options here.
1. UnitedHealth Group – 13.6% Market Share and over 84 Million Policyholders
With annual revenues of over $80 billion and a market share of 12.36%, United is the largest healthcare provider in the nation. A large portion of United’s business comes from its Medicare supplement and Medicare Part C coverage, which is endorsed by AARP. Medicare coverage is a booming industry as Americans live longer and expect quality healthcare for more years than in the past. United also offers many employer-administered group plans for governmental organizations and private enterprises.

When reviewing the data about the top health insurance companies in the USA it’s important to note that the Blue Cross Blue Shield brand is significantly higher than any of these reports detail at first look. Most health insurance companies often sell insurance under the same name nationwide but Blue Cross Blue Shield is actually an organization made up of many different chapters and collectively they had an 11% market share nationwide with over 68 Million policyholders. The average consumer would most likely view Blue Cross Blue Shield brand is the second largest health insurance company but for statistical purposes each BCBS chapter needs to be reported separately.

Are these the Best Health Insurance Companies in the USA?
Having a large market share is certainly one way to gauge customer satisfaction however it’s a little more complicated when it comes to health insurance. Most people have never voluntarily chosen one insurance company over the other but simply opted into a group plan offered from a single or very limited number of companies by their employer. Health insurance is very personal and you should never rely on any published market share report to determine whether or not a particular provider is the best health insurance company for your unique profile.
