Detailed Breakdown
Kaiser Permanente Kaiser Permanente has topped Insure.com‘s annual ranking for six straight years, with the score built 60% from a customer survey, 25% from NCQA health plan ratings, and 15% from NAIC complaint index data. It also posts a notably low 8.1% denial rate on its EPO plans. The catch: Kaiser and Molina offer the best rates but aren’t available in every state — Kaiser currently operates in California, Colorado, DC, Georgia, Hawaii, Maryland, Oregon, Virginia, and Washington.
Blue Cross Blue Shield (BCBS) BCBS wins on reach. It’s the overall leader for plan variety, offering HMO, PPO, EPO, and POS options with Silver-tier HMO plans averaging $490/month. It also earned the highest digital experience score among analyzed companies for online premium payment and account management, though it has also drawn negative feedback over denied claims and high premiums in some regions, despite praise for its extensive provider network.
UnitedHealthcare For sheer scale, UnitedHealthcare offers the nation’s largest network — over 1.3 million providers and 6,500 hospitals — paired with comprehensive coverage and digital health tools. This makes it a strong pick if you travel often or want flexibility in choosing doctors.
Aetna If low hassle at claim time matters most, Aetna posts the lowest complaint level among the companies analyzed, which typically signals a smoother claims process and stronger member satisfaction.
Oscar & Ambetter For marketplace shoppers focused purely on price, NerdWallet’s picks for best marketplace health insurance highlight Oscar for low premiums and Ambetter for dental coverage.
Cigna Cigna stands out for international travelers and expats, thanks to its global network and highly rated virtual care — though its ACA plan availability is limited in some states.
Cost Breakdown by Metal Tier (2026)
| Metal Tier | Avg. Monthly Premium | Notes |
|---|---|---|
| Bronze (EPO) | ~$501 | Lowest starting premium |
| Bronze (POS) | ~$692 | Most expensive at Bronze |
| Silver (POS) | ~$661 | Drops below HMO at this tier |
| Silver (KFF benchmark, 40yo) | ~$625 | Up from $497 in 2025 |
| Platinum (EPO) | ~$1,317 | Highest tier cost |
One pattern many shoppers miss: EPO plans start as the cheapest option at Bronze but become the most expensive by Platinum, while POS plans start most expensive at Bronze and become the cheapest by Silver.
How to Save Money on Health Insurance
- Check subsidy eligibility first — many ACA marketplace buyers qualify for premium tax credits that aren’t reflected in “sticker price” quotes.
- Compare metal tiers, not just brands — the cheapest plan type at Bronze isn’t always cheapest at higher tiers, so re-compare at your likely usage level.
- Use a marketplace calculator before shopping — a Health Insurance Marketplace Calculator helps estimate monthly costs and whether you qualify for subsidies before comparing carriers.
- Check network size against your actual doctors — a cheaper plan with an out-of-network primary doctor often costs more long-term.
- Review NAIC complaint data — a low sticker price from a high-complaint insurer can cost you in denied claims and appeal time.
Coverage Types & Plan Structures Explained
- HMO (Health Maintenance Organization): Lower premiums, requires a primary care doctor and referrals for specialists.
- PPO (Preferred Provider Organization): More flexibility to see specialists without referrals, usually higher premiums.
- EPO (Exclusive Provider Organization): No referrals needed, but no out-of-network coverage except emergencies.
- POS (Point of Service): Hybrid of HMO and PPO — needs referrals but allows some out-of-network care at higher cost.
- Metal Tiers (Bronze to Platinum): Higher tiers mean higher premiums but lower out-of-pocket costs when you actually use care.
