Cigna vs. Kaiser Permanente: ACA Health Insurance

In Moneygeek's analysis of 2026 ACA marketplace plans, Kaiser Permanente earned a 94.6 Quality Rating System score versus Cigna's 73.71 and approved 92% of claims versus Cigna's 77% approval rate. Kaiser Permanente's monthly premiums are $158 to $205 lower than Cigna's across both plan types.

Cigna covers 11 states while Kaiser Permanente operates in seven, with Colorado and Virginia as the only overlapping markets. ACA plans apply to working-age adults under 65, while Medicare sections apply to adults 65 and older or those with qualifying disabilities.

Cigna and Kaiser Permanente limit network options to HMO and EPO plans. Neither insurer offers PPO or POS coverage. HMO plans require you to select a primary care doctor, who manages your treatment and issues referrals to specialists. EPO plans let you see specialists without a referral. Both plan types limit coverage to network providers except in emergencies.

Kaiser Permanente's 20.9-point quality advantage doesn't come with a higher price tag. HMO members save $1,896 per year by choosing Kaiser Permanente over Cigna; EPO members save $2,460.
Kaiser Permanente scores 96.11 in medical care quality, Cigna scores 71.73. That 24-point gap is the largest single-dimension difference in our QRS comparison. Plan administration tells a similar story: Kaiser Permanente at 91.68 versus Cigna's 80.29.

Cigna scores 93.59 versus Kaiser Permanente's 91.51. That 2-point lead doesn't close the overall gap: Kaiser Permanente's total QRS score is 94.6 against Cigna's 73.71.

Kaiser Permanente rejects 8.3% of claims while Cigna rejects 23%. Cigna members see their claims denied at nearly three times the rate of Kaiser Permanente members.
Kaiser Permanente wins on price and quality, but its seven-state footprint is a real constraint. If you live outside California, Colorado, Hawaii, Maryland, Oregon, Virginia or Washington, Kaiser Permanente isn't an option. Cigna's 11-state presence covers nine states Kaiser Permanente doesn't: Arizona, Florida, Georgia, Illinois, Indiana, Mississippi, North Carolina, Tennessee and Texas.

For residents of those states, Cigna is the only choice between these two insurers. If you're in an overlapping state and have frequent out-of-state travel or care needs, Kaiser Permanente's tighter network may also create coverage problems since both insurers limit you to HMO and EPO networks.
Cigna's 23% denial rate is the number that should give prospective members pause. In our analysis, that's nearly one in four submitted claims rejected, versus one in 12 at Kaiser Permanente. Members who anticipate regular care, prescription management or specialist visits will notice that difference.

Cigna's medical care QRS score of 71.73 also trails Kaiser Permanente by 24 points, a gap too large to attribute to measurement variance. Buyers in Colorado or Virginia, where both insurers operate, should compare Kaiser Permanente plans first given the price and quality data.

Cigna uses Attained Age pricing, which means premiums increase as policyholders age. Plan G starts at $162 per month at 65 and reaches $203 by 75. Plan N costs $175 at 65 and rises to $227 at 75. Plans A through D range from $205 to $269 at 65 and from $249 to $318 at 75.

F	$252	N/A	$307	N/A
G	$162	N/A	$203	N/A
N	$175	N/A	$227	N/A

Plan G is Cigna's most cost-efficient starting point at $162 per month for a 65-year-old, the lowest entry price among Cigna's available plans. The $41 monthly increase to age 75 reflects Attained Age pricing compounding over time. Buyers who expect to hold a Medigap plan for 15-plus years should model total 10-year cost, not just the age-65 rate.

Plan G costs $1,944 per year at 65 and $2,436 per year at 75, a $492 annual increase over that decade. A buyer who enrolls at 65 and holds Plan G to 75 pays $492 more in their 10th year than in their first. That's the Attained Age curve made concrete. Issue Age and Community Rated Medigap plans don't work this way, your age at enrollment either locks your rate or pools it with other members.

And because Kaiser Permanente doesn't sell Medigap at all, shoppers in this category should compare Cigna against other Medigap carriers. Plan G from a Community Rated insurer in your state is the most direct alternative to Cigna's Attained Age Plan G for buyers concerned about long-term rate growth.

Cigna vs. Kaiser Permanente: Medicare Advantage

Cigna operates Medicare Advantage plans in 29 states compared to Kaiser Permanente's eight-state footprint. Cigna includes 86% of plans with $0 premiums versus Kaiser Permanente's 36%. Kaiser Permanente has a 4.37 CMS Star rating compared to Cigna's 3.66 and lower maximum out-of-pocket limits. Cigna offers PPO plans while Kaiser Permanente limits plan types to HMO and HMO-POS networks.

Cigna and Kaiser Permanente overlap in Colorado, Georgia, Maryland, Oregon, Virginia and Washington. California and Hawaii are Kaiser Permanente's exclusive markets in this comparison, with neither served by Cigna's Medicare Advantage plans. Cigna is the single Medicare Advantage option in 23 states. Kaiser Permanente limits plan types to HMO and HMO-POS networks while Cigna adds PPO flexibility for members who want out-of-network provider access.

Cigna HMO plans average $8 per month, with 85% requiring no premium beyond Medicare Part B. Kaiser Permanente charges $46 per month on average for HMO plans, with 38% offering $0 premiums. HMO-POS plans cost $34 for Cigna versus $46 for Kaiser Permanente and Cigna has more zero-premium options at 60% compared to Kaiser Permanente's 31%.


HMO	85%	38%	$8	$46	$5,585	$4,815
HMO-POS	60%	31%	$34	$46	$5,329	$5,708
PPO	83%	N/A	$1	N/A	$6,578	N/A

Kaiser Permanente's HMO maximum out-of-pocket limit is $4,815 versus Cigna's $5,585. That $770 difference is what a member with serious illness or hospitalization could pay out-of-pocket before coverage takes effect. Cigna's lower premiums don't eliminate that gap, for high-utilization members, Kaiser Permanente's lower ceiling likely saves more than Cigna's $38 monthly premium advantage on HMO plans.

That $456 annual premium saving deserves a closer look. Cigna's HMO members pay $456 less per year than Kaiser Permanente's, but carry $770 more in maximum out-of-pocket exposure, a member who hits the MOOP ceiling in a high-utilization year ends up $314 worse off with Cigna than with Kaiser Permanente, even after accounting for the premium saving. The math only favors Cigna for members who stay healthy enough to avoid large claims. For anyone managing a chronic condition or expecting surgery, Kaiser Permanente's $4,815 ceiling is the number that matters.

Kaiser Permanente holds 4.37 stars for both HMO and HMO-POS plans. Plans at this rating qualify for special enrollment periods and Medicare quality bonuses. Cigna's HMO plans average 3.77 stars and its HMO-POS plans reach 3.96. Cigna's PPO plans average 3.01, below the 4-star threshold for quality bonuses. Plans rated four stars or higher receive enhanced dental, vision or hearing benefits, Kaiser Permanente's plans qualify; none of Cigna's plans do.
Buyers outside California, Colorado, Georgia, Hawaii, Maryland, Oregon, Virginia and Washington have no access to its plans at all. Kaiser Permanente provides only HMO and HMO-POS plans, so members who need out-of-network provider access, whether for a specialist, a second opinion or care while traveling, have nowhere to go within this insurer.

Buyers on fixed incomes who need a $0-premium plan should also look elsewhere first.

Only 36% of Kaiser Permanente's Medicare Advantage plans have no monthly premium, compared to 86% at Cigna. And for HMO-POS plans specifically, Kaiser Permanente's average maximum out-of-pocket of $5,708 is actually $379 higher than Cigna's $5,329, the one plan type where Kaiser Permanente's cost protection advantage disappears entirely.
None of Cigna's Medicare Advantage plans reach the four-star CMS threshold that qualifies members for enhanced dental, vision or hearing benefits. Its HMO plans average 3.77 stars, its HMO-POS plans 3.96 and its PPO plans 3.01. For buyers who use their Medicare Advantage coverage heavily, that quality gap translates directly into fewer supplemental benefits and no access to Medicare's quality bonus enrollment periods.

Cigna's PPO plans offer the out-of-network flexibility Kaiser Permanente can't match, but they carry a $6,578 average maximum out-of-pocket the highest of any plan type in this comparison and the weakest star rating at 3.01. Buyers choosing Cigna PPO for flexibility are accepting both higher cost exposure and lower rated coverage. Members with high usage who qualify for Kaiser Permanente's service area are better protected by Kaiser Permanente's $4,815 HMO maximum out-of-pocket ceiling.

Which One Should You Choose?

Kaiser Permanente is the stronger ACA marketplace option: its 94.6 QRS score, 8.3% claim denial rate and lower premiums across both plan types make a clear case. Cigna is the only Medicare Supplement option since Kaiser Permanente doesn't sell Medigap. For Medicare Advantage, the choice comes down to priorities: Cigna's 86% zero-premium plans and 29-state reach versus Kaiser Permanente's 4.37 CMS star rating and $770 lower HMO out-of-pocket cap. Buyers in overlapping states with frequent care needs should lean toward Kaiser Permanente. Buyers prioritizing low monthly cost or PPO access should compare Cigna.
