Humana and Kaiser Permanente take almost opposite approaches to Medicare Advantage. Humana is a nationwide carrier available in the vast majority of states. Kaiser is a regional, tightly integrated system available in only 8 states and Washington D.C. — but where it operates, it routinely posts some of the highest quality ratings in the entire industry. Here’s how they actually compare in 2026.
The Quick Answer
- Kaiser Permanente consistently earns some of the highest CMS star ratings of any Medicare Advantage carrier — virtually all of its members are enrolled in plans rated 4 stars or higher — thanks to an integrated model where Kaiser owns its own hospitals and clinics. The catch: it’s only available in 8 states plus D.C.
- Humana trades some of that consistency for reach — it’s available in far more states and counties, with strong dental, vision, and hearing benefits on every plan, but its average star rating (around 3.61 in 2026) trails Kaiser’s by a wide margin.
If you live in Kaiser’s service area, it’s genuinely one of the highest-rated options available anywhere in the country. If you don’t, Humana is likely to be one of your broadest-reaching alternatives.
Kaiser Permanente Medicare Advantage
Kaiser is structured differently from almost every other major Medicare Advantage carrier: instead of contracting with a network of independent doctors and hospitals, Kaiser owns and operates its own facilities and employs its own physicians. That integration is the whole story behind its ratings.
What stands out about Kaiser in 2026:
- Available in only 8 states (California, Colorado, Georgia, Hawaii, Maryland, Oregon, Virginia, Washington) plus Washington D.C.
- Roughly 1.9–2 million Medicare Advantage members, making it the fifth-largest MA insurer nationally despite its limited footprint
- Virtually all Kaiser MA members are enrolled in plans rated 4 stars or higher — a consistency almost no other carrier matches
- Five separate Kaiser health plans earned the full 5-star rating for 2026, out of only 34 five-star contracts nationwide
- Frequently posts 4.5–5 star ratings in California, Colorado, and Oregon specifically
- Best-in-class scores on member complaints — a reflection of coordinated care across primary care, specialists, and pharmacy all being part of the same system
Where it tends to fall short: it’s simply not an option for the vast majority of the country. If you live outside its 8-state service area, Kaiser isn’t available to you at all — and even within its footprint, you’re committing to Kaiser’s own network of doctors and hospitals with essentially no flexibility to go outside it for routine care.
Humana Medicare Advantage
Humana takes the traditional Medicare Advantage approach: a broad network of contracted, independent providers, spread across nearly the entire country.
What stands out about Humana in 2026:
- One of the broadest Medicare Advantage footprints in the country, though it did exit 3 states and 194 counties for 2026 as part of a broader industry pullback to protect margins
- An average CMS star rating around 3.61 for 2026, with roughly 20% of members in plans rated 4 stars or higher — individual contracts range widely, from about 3.0 up to 4.5 stars
- Dental, vision, and hearing coverage included on all plans, with some D-SNP (Special Needs Plan) options offering dental allowances up to $5,000
- Competitive OTC (over-the-counter) allowances and wellness perks like SilverSneakers
- Part B Giveback benefits on many plans
Where it tends to fall short: its average star rating is meaningfully lower than Kaiser’s, and like most major carriers, Humana has been trimming some extra benefits and narrowing certain networks for 2026 to manage rising costs.
Side-by-Side Comparison
| Humana | Kaiser Permanente | |
|---|---|---|
| States available | Most of the U.S. (reduced slightly for 2026) | 8 states + Washington D.C. |
| Average CMS star rating (2026) | ~3.61, ranges 3.0–4.5 by contract | Near-universal 4+ stars; multiple 5-star plans |
| Network model | Contracted network of independent providers | Owned facilities, employed physicians (fully integrated) |
| Dental/vision/hearing | Included on all plans | Included, varies by region |
| Member satisfaction | Mixed, varies by plan | Best-in-class complaint scores |
| Best known for | National reach, extra benefits, D-SNP dental | Highest quality ratings, coordinated care |
Pros and Cons
Kaiser Permanente — Pros:
- Among the highest CMS star ratings of any carrier, consistently
- Fully coordinated care — your primary doctor, specialists, hospital, and pharmacy are all in the same system
- Best-in-class member satisfaction scores
Kaiser Permanente — Cons:
- Only available in 8 states plus D.C. — not an option for most of the country
- Little to no flexibility to see providers outside the Kaiser system for routine care
- Moving out of Kaiser’s service area means starting your plan search over
Humana — Pros:
- Available in far more states and counties nationally
- Strong dental/vision/hearing benefits on every plan, with generous D-SNP dental options
- Broad network of independent providers to choose from
Humana — Cons:
- Average star rating trails Kaiser’s significantly
- Individual plan quality varies a lot — some contracts as low as 3.0 stars
- Network and benefit cuts in some states and counties for 2026
Which One Should You Choose?
- Choose Kaiser Permanente if: you live in one of its 8 states (or D.C.), you’re comfortable receiving all your care within one integrated health system, and quality ratings and coordinated care matter most to you.
- Choose Humana if: you live outside Kaiser’s service area (which is true for most of the country), you want a broad network of independent providers, or you specifically want strong dental benefits through a D-SNP plan.
For most people reading this, the decision will actually be made for you by geography — Kaiser simply isn’t available outside its 8-state footprint. If you do live in one of those states, though, it’s worth taking a close look, since its star ratings are genuinely hard to match.
Frequently Asked Questions
Is Kaiser Permanente available nationwide? No. Kaiser Medicare Advantage plans are only available in California, Colorado, Georgia, Hawaii, Maryland, Oregon, Virginia, Washington, and Washington D.C.
Why does Kaiser get such high star ratings? Kaiser owns its own hospitals and clinics and employs its own doctors, rather than contracting with independent providers. That integration — shared electronic health records, coordinated referrals, unified pharmacy — tends to reduce duplicate testing and medication errors, which shows up directly in CMS quality metrics.
Can I keep my current doctor with a Kaiser plan? Generally no, unless your doctor is already part of the Kaiser system. Enrolling in Kaiser typically means switching to Kaiser-affiliated providers for your routine care.
Did Humana reduce its coverage area for 2026? Yes. As part of an industry-wide pullback to manage costs, Humana exited 3 states and 194 counties for the 2026 plan year. Always confirm current availability in your specific ZIP code.
Does a lower Humana star rating mean a bad plan? Not necessarily — averages blend many different contracts. Some Humana plans rate as high as 4.5 stars. Always check the specific plan’s rating for your county rather than relying on the company-wide average.
Bottom Line
Humana and Kaiser Permanente represent two different philosophies: Humana bets on national reach and broad provider choice, while Kaiser bets on tight integration and consistently high quality within a limited footprint. If you live in Kaiser’s 8-state service area, its star ratings are hard to beat. Outside that footprint, Humana is one of the more broadly available options, though it’s worth checking the specific plan’s rating in your county rather than the company average.
