Which one is better, Cigna or Aetna?

Neither Cigna nor Aetna is universally better; the right choice depends on your network needs, prescription drugs, and location.

Network and Availability

• Aetna: Generally features a larger domestic U.S. network and higher overall market share, making it strong for stateside care and group employer plans. Owned by CVS Health, it integrates well with CVS pharmacy benefits and MinuteClinics.
• Cigna: Excels in global and international coverage, but its domestic U.S. network can be more concentrated in specific metro areas rather than rural regions.

Costs and Plan Features

• Aetna: Often scores higher on government and Medicare ratings, but can have higher average out-of-pocket costs or copays depending on the plan.
• Cigna: Frequently praised for digital user tools, wellness incentives, and diverse dental plan options. However, user reviews note occasional friction with medication pre-authorizations.

Which Should You Choose?

• Choose Aetna if: You want a massive domestic doctor network, easy access to CVS-affiliated services, or strong Medicare Advantage options.
• Choose Cigna if: You need robust international coverage, prefer strong digital/wellness tools, or want multi-tiered dental options.

Doctors and healthcare systems leave Aetna's network primarily due to disagreements over reimbursement rates, heavy administrative burdens, and failed contract negotiations.

Key Reasons Providers Leave Aetna

• Low Reimbursement Rates: Providers often state that Aetna's payment rates do not keep up with inflation, rising operational costs, or the rates paid by other insurers.
• Administrative Hassles: Doctors face extensive paperwork, prior authorization (precertification) requirements, and claim denials that increase office overhead and delay care.
• Contract Impasses: When annual or multi-year contracts expire, Aetna and large medical groups (such as university health systems or regional hospitals) frequently fail to agree on financial terms, forcing providers out-of-network.
• Aetna's Market Reductions: Parent company CVS Health has pulled back from specific regional markets, scaling back certain Affordable Care Act (ACA) exchange footprints and Medicare Advantage plans, which structurally alters local networks.

Cigna is generally considered larger than Aetna in total corporate revenue and overall membership when counting Cigna's massive pharmacy benefit management division, Evernorth, though Aetna has a larger direct medical insurance membership base and broader domestic footprint.

Size Comparison Breakdown

• Total Revenue and Parent Size: The Cigna Group brings in higher overall revenue due to Evernorth (including Express Scripts), whereas Aetna operates as a subsidiary of CVS Health, which itself has massive total retail and pharmacy revenue.
• Medical Memberships: Aetna provides traditional health insurance and medical plans to roughly 36 to 39 million people. Cigna Healthcare's direct medical plan membership is smaller, covering around 20 million domestic medical members, though it serves millions more globally and through pharmacy services.
• Domestic Network: Aetna features a larger direct U.S. provider and hospital network footprint across more states, while Cigna stands out more for its extensive international coverage network.
• User Sentiment: Opinions on Reddit show mixed experiences for both companies, with users noting that service quality often depends more on local doctor availability than the parent company's national size.

Doctors and medical groups are dropping or considering dropping Cigna Healthcare primarily due to its controversial automatic downcoding policy for office visits and ongoing reimbursement and contract disputes.

Automatic Downcoding Policy

• Lower Payments: Cigna implemented a policy that automatically "downcodes" higher-level Evaluation and Management (E/M) office visits (such as levels 4 and 5) to lower levels without reviewing the actual medical records.
• Administrative Burden: Instead of getting paid appropriately by default, physicians are forced to file tedious, time-consuming written appeals with full documentation to reverse the downcoding, taking time away from patient care.
• Regulatory Pushback: Medical associations and state regulators—such as the Maryland Insurance Administration—have pushed back or ordered halts on these types of automated underpayment practices, citing legality and fairness concerns.

Contract and Reimbursement Disputes

• Profit Pressures: Major for-profit insurers face pressure to improve margins, leading to aggressive utilization of automated claims adjustments, strict prior authorizations, and low reimbursement rates.
• Network Terminations: Health systems and independent physician groups frequently clash with Cigna during annual contract renewals over fair compensation, resulting in some regional networks dropping Cigna coverage entirely.

UnitedHealth Group is the No. 1 health insurance company in the United States by size, market share, and net premiums written.

When looking at customer satisfaction and quality ratings, Kaiser Permanente frequently ranks as the No. 1 overall health insurance provider for customer experience and plan performance. Other top-rated and major national providers include Blue Cross Blue Shield, Aetna (CVS Health), and Centene Corporation.

Top Health Insurers by Category

• Largest by Enrollment and Revenue: UnitedHealth Group (serving roughly 45 to 49 million members).
• Best for Customer Satisfaction: Kaiser Permanente, which combines coverage and care in an integrated system.
• Best for National Network & Variety: Blue Cross Blue Shield Association (offering local plans across all 50 states).
