Who is bigger, Humana or Aetna?

The main downside of Humana includes below-average customer satisfaction, a high volume of complaints regarding claim denials, and a recent drop in quality star ratings from the Centers for Medicare & Medicaid Services (CMS).

Customer Satisfaction and Quality Ratings

• Low satisfaction scores: Humana ranks below average for customer satisfaction in the majority of Medicare markets according to J.D. Power studies.
• Declining star ratings: Only about 37% of Humana members are enrolled in plans rated 4 out of 5 stars or higher by CMS, reflecting a notable drop in quality ratings.
• User complaints: Many customers report long hold times, unhelpful offshore customer service, and difficulties with billing errors or unauthorized dis-enrollments.

Network and Coverage Limitations

• Strict provider networks: Many plans—particularly HMO options like Humana Gold Plus—restrict care to a specific network of doctors and require primary care physician referrals or prior authorizations for specialists. Going out-of-network can lead to steep or complete out-of-pocket costs.
• Claim denials: Users frequently log complaints about denied coverage for specific medical procedures, prescription drugs, dental care, and vision benefits.
• Regional exits: Humana has scaled back or exited underperforming counties and commercial markets (such as the ACA marketplace), which can lead to reduced plan choices or disruption in local availability.

Lack of Under-65 Commercial Options

• No individual under-65 plans: Humana has fully exited the Affordable Care Act (ACA) marketplace, short-term medical plans, and employer-sponsored group health insurance, meaning they do not offer health plans for individuals under 65 who do not qualify for Medicare, Medicaid, or military coverage.

Doctors and health systems are leaving Humana's Medicare Advantage networks mainly due to payment disputes, low reimbursement rates, and rising operational costs.

As detailed by Newsweek, private insurers like Humana trim networks and drop unprofitable plans to boost profit margins. At the same time, many major hospital systems are choosing to cut ties with insurance networks.

Key Reasons for the Split

• Low Pay Rates: Humana often pays doctors and hospitals less than traditional government Medicare pays for the same care.
• Payment Delays: Health systems state that insurers fail to meet contract payment terms or slow down approvals for patient care.
• Rising Costs: Hospitals face higher expenses for staff and technology, making low insurance payouts unsustainable.
• Profit Goals: Humana cuts plans in certain counties to reach financial targets, which forces doctors and patients out of network.

Reports from KFF Health News show that when large medical groups drop these plans, patients must choose between finding new doctors or switching their insurance coverage.

The primary downsides of Aetna health insurance include high customer service complaints, above-average out-of-pocket maximum limits, and a complete exit from the individual Affordable Care Act (ACA) marketplace.

⚠️ Common Disadvantages of Aetna

• Customer Service Hurdles:
  • Long hold times
  • Unhelpful or uncoordinated representatives
  • Delayed claims processing
• High Out-of-Pocket Costs:
  • Higher maximum out-of-pocket (MOOP) limits compared to some competitors
  • Higher average monthly premiums on certain individual or family products
• Stricter Prior Authorizations:
  • Higher-than-average denial rates for certain Medicare Advantage prior authorization requests
• Reduced Marketplace Availability:
  • No longer offers individual or family ACA-compliant marketplace plans (withdrawn as of 2026), shifting focus strictly to employer, group, and Medicare markets.

Aetna is reducing its footprint by dropping nearly 90 Medicare Advantage plans across 34 states and exiting the Affordable Care Act (ACA) Marketplace entirely across 17 states.

Aetna stopped offering individual and family plans on the ACA Health Insurance Marketplace at the end of 2025 across 17 states, affecting about one million enrollees. Full individual market exits include:

Medicare Advantage Reductions

Aetna is cutting specific plans (mostly PPOs) and reducing county-level availability across 34 states for the 2026 plan year, continuing a strategy into 2027 of shedding hundreds of thousands of enrollees nationwide.

• Specific county-level pullbacks include New Hampshire (Belknap, Carroll, Cheshire, Grafton, Merrimack, Strafford, and Sullivan counties) and widespread plan discontinuations in states like Pennsylvania, Florida, Texas, and Georgia.

Neither UnitedHealthcare is universally better than Aetna; the right choice depends on your specific needs, location, and whether you want a larger provider network or better quality ratings.

Network and Coverage

• UnitedHealthcare: Offers a massive national footprint with a large provider network available across all 50 states. It often stands out for robust individual and health savings account (HSA) options.
• Aetna: Owned by CVS Health, it provides near-nationwide coverage and frequently scores higher on government quality ratings, particularly for Medicare Advantage plans.

Costs and Perks

• UnitedHealthcare: Tends to feature lower maximum out-of-pocket spending caps on certain Medicare plans, though general plans can sometimes carry higher price points.
• Aetna: Frequently features a higher percentage of $0-premium plans and integrates well with CVS pharmacy benefits (CVS Caremark).

Customer Satisfaction

• Both major insurers often score around the industry average or slightly below on independent customer satisfaction surveys, meaning experiences can vary significantly depending on your local market.
