Kaiser Permanente Medicare star ratings
Average star rating, weighted by enrollment: 4.41
Kaiser Permanente Medicare Advantage plans are rated well above the industry average, receiving an average rating of 4.41 stars out of 5 from the Centers for Medicare & Medicaid Services (CMS) for 2025, weighted by enrollment. For comparison, the average weighted star rating for plans from all providers is 3.95.
CMS maintains its own database of star ratings, which rank each plan from best (5 stars) to worst (1 star). The agency bases these ratings on plans’ quality of care and measurements of customer satisfaction, and ratings may change from year to year.
. For Medicare Advantage prescription drug plans with a premium, Kaiser’s average monthly premium is $82.85, which is higher than most competitors.
Even as a Medicare Advantage user, you’ll still be responsible for paying your Medicare Part B premium, which is $185 per month in 2025. However, some plans cover part or all of this cost
Requirements for copays, coinsurance and deductibles vary depending on your plan, location and the services you use. Other out-of-pocket costs to consider include:
Whether the plan covers any part of your monthly Medicare Part B premium.
The plan’s yearly deductibles and any other deductibles, such as a drug deductible.
Copayments and/or coinsurance for each visit or service. For instance, there may be a $10 copay for seeing your primary doctor and a $45 copay for seeing a specialist.
The plan’s in-network and out-of-network out-of-pocket maximums.
Whether your medical providers are in-network or out-of-network, or how often you may go out of network for care.
Whether you require extra benefits, and if the plan charges for them.

Kaiser Permanente Medicare Advantage plan types
Kaiser Permanente offers mostly HMO Medicare Advantage plans, but also offers some PPO plans.
Plan availability may vary by county. Plan offerings may include the following types:
HMO plans
A health maintenance organization (HMO) generally requires that you use a specific network of doctors and hospitals. You may need a referral from your primary doctor in order to see a specialist, and out-of-network benefits are usually very limited.
HMO-POS plans
HMO point-of-service plans are HMO plans that allow members to get some out-of-network services, but you’ll pay more for those services.
PPO plans
Preferred provider organization (PPO) plans provide the most freedom, allowing you to see any provider that accepts the insurance. You may not need to choose a primary doctor, and you don’t need referrals to see specialists. You can seek out-of-network care, although it may cost more than seeing an in-network doctor.
SNPs
Special needs plans (SNPs) restrict membership to people with certain diseases or characteristics. Hence, the benefits, network and drug formularies are tailored to the needs of those members. Kaiser Permanente offers one type of SNP:
Dual-Eligible SNP: For people who are entitled to Medicare and who also qualify for assistance from a state Medicaid program.

Medicare Advantage review methodology
The Medicare Advantage marketplace is concentrated among just a handful of companies; in many places, one insurer serves more than half of the market. NerdWallet reviewed 26 Medicare Advantage brands, with some insurers having more than one brand under their umbrella. (For example, Blue Cross Blue Shield includes the brands Anthem and Highmark.) At the national level, these reviews include nine of the 10 largest brands by enrollment. At the state level, our research includes at least one major insurer in 47 of the 49 states that offer Medicare Advantage plans, and includes the top two insurers in 35 of those states. (Alaska doesn't offer Medicare Advantage plans.) We also look at online search volume to identify regional and other notable players in the space.
NerdWallet’s Medicare Advantage reviews are based on ratings data from the Centers for Medicare & Medicaid Services, as well as pricing, plan availability by state, plan types available, consumer experience, extra benefits offered and more. These reviews are a guide, but we encourage you to shop around and compare several plans to find the best coverage and rate for you. NerdWallet does not receive compensation for any reviews.
