Aetna vs. Cigna vs. Kaiser Permanente 2021 Review

Updated February 2021.

Most of the advice published about health insurance focuses on how to choose an insurance plan that meets your needs. This article focuses on choosing a health insurance company.

Specific plans and costs discussed in this article may vary depending on your location, age, and other demographic information.

If you’re considering plans from any of these three companies, this article will help you better understand what each health insurer offers and which insurance carrier may be best for you.

We'll cover:

Best Company user ratings and reviews

Side-by-side comparison of customer ratings, 4 and 5 star reviews, and overall scores

(Ratings as of February 3, 2021)

Although each insurer has a fair number of 4- and 5-star reviews, each company also has a fair proportion of 1-star reviews. Aetna has 29 percent 1-star reviews. Cigna's is higher at 40 percent. Kaiser Permanente has 34 percent 1-star reviews.

Negative reviews are common in the health insurance industry. For all health insurance reviews received by Best Company in 2020, 24 percent were 1 star. In 2019, 41 percent were 1 star. Since we considered reviews from all years for Aetna, Cigna, and Kaiser Permanente, it's hard to say exactly how these companies compare to annual industry findings. However, the proportions of 1-star reviews each insurer has don't stand out considering industry patterns.

As you consider good and bad reviews about health insurance companies, keep in mind that insurers offer a wide variety of plans. Plans have different network structures, cost-sharing rules, and coverage restrictions. Health insurance plan offerings can also vary by location, so consider where the reviewer is from as you read reviews.

Everyone's medical needs are also different, which can affect how plan members experience the insurance provider. If reviewers share details on why they had difficulty, that can help you know what questions to ask and decide whether or not to buy from an insurance company.

Complaints about Aetna, Cigna, and Kaiser Permanente have similar themes. Reviews mention issues with claims, coverage denial, and difficulty resolving problems. These similarities show that the difficulties are common across these insurers. Choosing one over the other doesn't necessarily mean you'll avoid these problems.
