By far the most members of any health insurance provider, UnitedHealthcare (a division of UnitedHealth Group) stands head and shoulders above the competition. There are more than 45 million people covered by Anthem, making it the second biggest health insurance company. Following their acquisition by CVS Health Corp., Aetna and Wellpoint, which encompass multiple Blue Cross Blue Shield plans, are now under the ownership of Elevance Health (previously Anthem).
It boasts more members than any other customer-owned health insurance in the United States and provides coverage to residents of five states: Texas, Montana, New Mexico, and Oklahoma. The following health insurance providers rank highest in each state for both individual and group coverage. Kaiser Permanente holds 12.81 percent of the total health insurance market share for individual health insurance and plans in the ACA market, making it the largest overall health insurer. Additionally, Cigna continued to grow its small business health plan model, which it had started with Oscar Health. The size of an insurance company should not be the only factor considered when picking one.
Additional important factors to think about include coverage options, customer service, pricing, and network providers. It is wise to shop around for the plan that meets your requirements the best by comparing different options.
