Health insurance company ratings

In the health insurance industry, a variety of rating agencies evaluate health insurance companies every year based on factors that include financial strength, customer reviews and policyholder complaints. You can use these metrics to evaluate providers and choose the best insurance company for you. The most common third-party ratings for insurance companies include:

  • J.D. Power: J.D. Power is a global marketing information services company that ranks some of the best insurance companies on customer satisfaction. Its rankings give each insurer a number between 0 and 1,000 and use rating factors such as price, customer satisfaction, policy offerings and interaction.
  • A.M. Best Financial Strength Rating: A.M. Best is a credit rating agency that gives health insurance companies a financial health score. A++ or "Superior" is the top grade available. Usually, any company above A- is in an above-average financial situation.
  • Better Business Bureau (BBB): The BBB rating system is a grade given to a company between A+ and F, which is determined by its complaint history and how responsive the company is to complaints.

Checking company ratings and customer evaluations can help you understand what the company values and how it stacks up against its competitors. Then, you can get quotes from these companies to decide which one makes sense for your situation.

How to choose the best health insurance company

When choosing a health insurance company, you should evaluate the policy costs, company features, customer reviews and provider network.

Policy costs, details and company benefits

The most important factor to consider is whether the insurer offers affordable policies that fit your needs.

The price of a health insurance policy can vary widely by insurer. This is typically because some providers offer additional benefits with their policies, such as online member portals or gym memberships.

Additionally, some policies have a wider provider network, which means your health insurance would be accepted by more doctors and medical facilities. However, policies with a bigger network or those that offer you the ability to see any doctor that you want will almost always come with higher monthly premiums.

Finally, besides the monthly premium, you should carefully review the deductibles and copays or coinsurance before choosing a policy. These values can vary greatly not only by policy but also by insurer. By selecting the plan with a deductible and coinsurance that fit your needs, you can save yourself money.

Customer reviews

When evaluating insurers, you should also consider how other customers view the company. By collecting metrics like the NAIC Complaint Index and J.D. Power's customer satisfaction scores, you can better understand how that health insurance company values its policyholders.

Additionally, you should check reviews about the claims process and the ease in which consumers can get their claims filled. Some companies tend to have cheaper health insurance but will lag significantly in customer service. This is important to consider, as claims processing will be integral to your overall customer experience with the health insurance company.
