Aetna Medicare Advantage Plans: 2026 Coverage, Costs & Reviews

According to KFF's 2025 Medicare Advantage analysis, Aetna Medicare Advantage is the third-largest Medicare Advantage business in the U.S., accounting for approximately 12% of the entire MA market as part of CVS Health Corporation. In 2026, Aetna provides Medicare Advantage Prescription Drug plans in 43 states and Washington D.C., for approximately 57 million Medicare-eligible adults. The plans have an excellent rating. More than 81% of Aetna MA members are enrolled in 4-star or higher plans with CMS, and 63% of them are in a 4.5-star plan, according to CVS Health's announcement for the 2026 Star Ratings. This is well up from the industry weighted average of 4.02.

This guide explains what Aetna MA does in 2026, how it works with CVS pharmacy and CVS MinuteClinic, the costs and the real issues brokers need to discuss with their clients when considering CVS Health. Data sources include the CVS Health corporate disclosures, the CMS Star Ratings data, Medicare.gov, and KFF. 

What Aetna Medicare Advantage offers in 2026

Aetna's 2026 Medicare Advantage portfolio centers around three plan structures and several specialized products. The standard Medicare Advantage Prescription Drug (MAPD) plans bundle hospital, medical, and prescription coverage with the supplemental benefits typical of Medicare Advantage: dental, vision, hearing, fitness (SilverSneakers), and over-the-counter allowances.

What's notable about Aetna's 2026 offering:

• $0 premium plans available in every county where Aetna operates. Aetna estimates 82% of Medicare-eligible adults in their service areas have access to a $0 premium plan

• $2,100 annual out-of-pocket maximum on prescription drugs, matching the federally mandated cap

• $0 copay on Tier 1 drugs at in-network pharmacies for over 98% of existing General Enrollment MAPD members, with up to a 100-day supply

• C-SNP expansion to 18 states in 2026, including 16 new states, for members with diabetes, chronic heart failure, or specific cardiovascular conditions

• D-SNP plans for those dual-eligible for Medicare and Medicaid

• SilverScript stand-alone Part D plans ranging from $0 monthly (for full Extra Help recipients in 18 states) to $14.70 to $116 monthly for other members

The C-SNP expansion is the most consequential 2026 change. C-SNPs (Chronic Condition Special Needs Plans) cap copays at $0 for primary care and certain specialists treating the qualifying condition, plus carry an Extra Benefits Card. For someone with diabetes or heart failure shopping Medicare Advantage, an Aetna C-SNP can mean meaningfully lower out-of-pocket costs than a standard MAPD plan.

The CVS Health integration: real benefit or bundle play?

Aetna Medicare Advantage members get tighter integration with CVS Pharmacy and MinuteClinic than members of competing plans. CVS owns Aetna, and the parent company has invested heavily in connecting the pharmacy benefit manager (PBM, Caremark), retail pharmacy footprint (~9,000 locations), and the insurance plan into one ecosystem.

Where the integration creates real value:

• Prescription convenience. Filling at CVS, Walgreens, Walmart, Kroger, Albertsons, or H-E-B works at preferred pharmacy pricing. CVS doesn't lock members into CVS Pharmacy as the only preferred option, which surprised some observers.

• MinuteClinic access. The 1,000+ walk-in clinics inside CVS stores are in-network for Aetna MA members, often with $0 copays for routine care

• Mail order through Optum (despite being owned by UnitedHealthcare, this remains the prescription mail-order option for many Aetna plans) and CVS Caremark Mail Service

• Extra Benefits Card usability. Members can spend OTC and grocery allowances at participating CVS Pharmacy locations

Where the integration's value is overstated:

• Most major drugs are available everywhere. The CVS network advantage matters only if your specific medications need specialty handling

• MinuteClinics handle limited care. They're useful for vaccines, basic illness, minor injuries, but not chronic disease management or complex care

• Dental, vision, and hearing benefits are administered through third-party networks (Zelis, dental network partners) and are essentially identical across major Medicare Advantage carriers

Brokers I work with generally don't recommend Aetna because of CVS integration alone. The decision usually comes down to local provider networks and total out-of-pocket costs.

Aetna Medicare Advantage cost structure in 2026

Aetna medicare advantage cost varies by plan type and county. The general structure for 2026:

The $2,100 prescription drug OOP cap is new for 2025 onward, mandated by the Inflation Reduction Act. It applies to all Medicare Part D plans, not just Aetna. The cap protects members from catastrophic drug costs that could previously exceed $7,000 to $10,000 annually under the old "donut hole" structure.

For someone comparing Aetna against AARP/UnitedHealthcare or Humana in the same county, total cost calculations should focus on: (1) which of your providers are in each plan's network, (2) which of your prescription drugs are on each plan's formulary and at what tier, and (3) the maximum out-of-pocket exposure if you have a high-cost medical year.

What 2026 Star Ratings actually mean for Aetna

Aetna's 2026 Star Ratings performance is genuinely strong relative to competitors. The 81% of members in 4-star+ plans compares favorably to:

• UnitedHealthcare: 78% in 4-star+ plans for 2026

• Humana: 20% in 4-star+ plans for 2026 (a sharp decline from previous years)

• Industry average: 67% in 4-star+ plans

Star Ratings affect both members (through quality of care metrics) and insurers (4-star+ plans qualify for federal bonus payments). The ratings cover member satisfaction, customer service quality, complaints, member experience with care, and clinical care quality.

A few caveats worth noting:

• Specific plan ratings vary widely. "Aetna Medicare" as a contract has plans rated 2 stars (the lowest tier), per Healthcare Finance News reporting on the 2026 Star Ratings release. Always check the specific plan rating for your county before enrolling, not just the parent company's average

• The 81% figure is enrollment-weighted. Aetna's most popular plans tend to be highly-rated; less-popular plans may rate lower

• Star Ratings don't measure cost. A 4.5-star plan with high deductibles and limited drug coverage may cost more in real dollars than a 4-star plan with better cost-sharing structure

CVS Health legal concerns: what to know

To understand Aetna, it's important to note that legal challenges have cropped up against parent CVS Health in 2025 and 2026. Two stand out:

A federal court ordered CVS Caremark (the PBM subsidiary) to settle for almost $290 million in damages for allegedly overcharging Medicare over a decade on prescription drugs. CVS' long-term-care arm, Omnicare, filed for Chapter 11 bankruptcy separately after being fined $949 million by the federal government for overcharging for drugs.

Neither impacts Aetna Medicare Advantage members on a day-to-day basis or claims. However, they pose a valid question about CVS Health's compliance culture and financial constraints of the parent company. This context is important for members assessing the stability of the long-term plan. The move comes after regulators in some states have began to investigate CVS Health's Medicare businesses.

When Aetna makes sense

Aetna is worth strong consideration if:

• You take prescriptions and want the $2,100 annual cap with $0 Tier 1 copays

• You have a qualifying chronic condition (diabetes, heart failure, certain cardiovascular conditions) and could benefit from a C-SNP

• You're dual-eligible and Aetna offers a D-SNP in your area

• You fill prescriptions at CVS, Walgreens, Walmart, Kroger, or Albertsons (preferred pharmacies)

• Your providers are in-network in your specific county

Aetna may not be the best fit if:

• You prefer Original Medicare with Medigap for maximum provider flexibility

• Your providers aren't in Aetna's local network

• You're concerned about CVS Health's long-term stability given the parent company's legal issues

• The specific plan in your county has a low Star Rating (always verify on Medicare.gov)
