There are many good health insurers, but finding the one that best meets your needs takes some time.

To help, the Insure.com editors gathered rate data and looked at health insurers’ AM Best financial stability scores and National Committee for Quality Assurance ratings, which evaluate health plans on member satisfaction, among other factors. We also surveyed members to gauge each company’s level of customer experience and its policy offerings. We asked customers if they trusted their insurer, whether they planned to renew their current policies and what they thought about their insurance company’s digital experience.

Based on that data and other important insurance metrics, we rated the best health insurance companies of 2023 and gave each from one to five stars.

The top health insurer is Kaiser Permanente with 4.2 (or, more precisely, 4.164) stars, according to our analysis, followed closely behind by UnitedHealthcare also with 4.2 (or 4.158) and Aetna with 3.8 stars.

“Consumers certainly want to save money and receive a low premium when choosing an insurance company. However, it is important to also consider factors such as financial ratings, regulatory compliance and customer satisfaction,” says David Marlett, Managing Director, Brantley Risk & Insurance Center at Appalachian State University, and an Insure.com editorial advisor. “These rankings incorporate all of these issues and provide the consumer with a more comprehensive approach to evaluating insurance options.”

Below is a list of the top 10 health insurance companies and a review of each.

Insure.com in the fall of 2022 surveyed more than 1,500 people about insurance. The survey was conducted by online market research company Slice MR. Respondents were asked to rank their insurers.

The editors then selected – based on the number of survey responses – the top companies for further evaluation. 

Insure.com’s editors also gathered AM Best grades, National Committee for Quality Assurance (NCQA) scores and more to make their final selection of the nation’s best health insurance companies.

Some familiar names, such as Health Care Service Corp. and Oscar Health, didn’t make the top 10 list because those companies didn’t generate enough survey responses for the editors to do a fair evaluation.
