• Medical insurance (HMO, PPO, and other network designs)
• Prescription drug coverage
• Dental and vision benefits
• Behavioral health and mental health services
• Wellness programs, disease management, and care coordination
• Telehealth and digital health tools via the Aetna Health app and member portals

Aetna Medicare: Plans and Options

Aetna is a major player in the Medicare market, offering products for seniors and people with disabilities who are eligible for Medicare. Its Medicare lineup includes:

Medicare Advantage (Part C) Plans These private plans combine Medicare Part A (hospital) and Part B (medical) coverage and often include extra benefits not available under Original Medicare. Many Aetna Medicare Advantage plans also incorporate Part D prescription drug coverage (MAPD plans).

Common plan types:

• HMO — Requires use of in-network providers (except emergencies) and usually a primary care physician (PCP) with referrals for specialists.
• HMO-POS — Similar to HMO but with limited out-of-network options at higher cost.
• PPO — Greater flexibility to see out-of-network providers (at higher cost-sharing); referrals typically not required.
• Special Needs Plans (SNPs) — Designed for specific populations:
  • Dual-Eligible SNPs (D-SNPs) for people eligible for both Medicare and Medicaid
  • Chronic Condition SNPs (C-SNPs) for those with certain severe or disabling chronic conditions
  • Institutional SNPs (I-SNPs) for people in long-term care facilities

Medicare Prescription Drug Plans (Part D) Standalone drug plans that can be paired with Original Medicare. Features often include preferred pharmacy networks, mail-order options, and coverage for a range of medications.

Medicare Supplement (Medigap) Insurance These plans help cover out-of-pocket costs left by Original Medicare (deductibles, coinsurance, and copayments). They do not include prescription drug coverage and generally have no network restrictions for Medicare-accepting providers.

Additional Supportive Benefits Commonly Found in Aetna Medicare Advantage Plans

• Routine dental, vision, and hearing coverage (including hearing aids in many plans)
• Fitness benefits such as SilverSneakers
• Over-the-counter (OTC) allowances via a benefits card
• Transportation to medical appointments
• Meal programs after hospital stays
• Care coordination and personalized support for members with chronic conditions
• $0 or low copays for primary care and certain preventive services in many plans
• Annual out-of-pocket maximums that limit total member spending on covered services

Many plans offer $0 monthly premiums (members still pay the standard Medicare Part B premium). Availability, benefits, and costs vary significantly by county and plan.

Aetna has also offered specialized options such as Medicare Eagle plans that coordinate with VA benefits for eligible veterans.

Star Ratings and Quality Focus

Aetna has reported strong performance in CMS Star Ratings for many of its Medicare Advantage contracts. In recent years, a high percentage of its Medicare Advantage members have been enrolled in plans rated 4 stars or higher. Strong Star Ratings can translate into higher quality bonuses and better plan stability.

Key Advantages of Aetna Medicare Advantage

• Integrated medical and often prescription drug coverage in one plan
• Extra benefits beyond Original Medicare (dental, vision, hearing, fitness, OTC, transportation)
• Care management and support for chronic conditions
• Access to a large provider network (scope varies by plan type and location)
• Digital tools including the Aetna Health app for claims, ID cards, and support
• Coordination opportunities through the broader CVS Health network

Plan Types, Eligibility, and Costs

Eligibility

• Must be enrolled in Medicare Part A and Part B
• Live in the plan’s service area
• SNPs have additional eligibility criteria based on dual eligibility, chronic conditions, or institutional status

Cost Factors

• Monthly plan premium (many $0 options available)
• Medicare Part B premium (still required)
• Deductibles, copays, and coinsurance
• Annual out-of-pocket maximum
• Prescription drug costs (tiers, preferred pharmacies, mail order)

Costs and benefits change annually and differ by location. Always review the Summary of Benefits and Evidence of Coverage for the specific plan and year.

Customer Experience Insights

Member feedback is mixed but often highlights:

• Convenience of extra benefits (dental, vision, fitness)
• Useful mobile app and digital tools
• Solid coverage for routine and preventive care
• Occasional frustrations with prior authorizations, claim processing times, or customer service consistency

Overall ratings across review platforms typically fall in the mid-range (around 3.5–4.0 out of 5), with performance varying by plan type and region.
