The real monthly cost breakdown — Aetna plan premium, Medicare Part B, Part D drug cap, copays by plan type — plus the honest comparison against Blue Cross and UnitedHealthcare that most guides skip.
Aetna Medicare Advantage plan premiums range from $0 to $204/month depending on plan type and location. But every senior still owes the Medicare Part B premium — $202.90/month in 2026 — regardless of which Aetna plan they choose. High-income earners pay even more through IRMAA surcharges. That Part B amount is the floor of your monthly Medicare cost.
Aetna is now part of CVS Health — and that ownership shapes what makes it genuinely different from competitors. With over 3.5 million Medicare Advantage members, plans available in 43 states and Washington D.C., and some of the highest CMS Star Ratings among major carriers, Aetna sits in a strong position. But the right question isn’t whether Aetna is good in general. It’s whether the specific plan available in your county fits your doctors, your prescriptions, and your realistic annual healthcare use.

How much does Aetna Medicare Advantage cost per month for a single person? Aetna plan premium: $0 to $184/month (HMO) or up to $204/month (PPO) · Plus Part B premium still owed: $202.90/month standard · Total monthly baseline: $202.90 to $406.90 before copays · 82% of Medicare-eligible seniors in Aetna’s service areas have access to a $0-premium plan · What you actually pay varies entirely by your county — enter your ZIP at aetna.com to see real plan optionsThe “$0 premium” language in most Aetna marketing is accurate but incomplete. When Aetna says a plan has a $0 premium, it means you pay Aetna nothing on top of what Medicare already deducts from your Social Security check each month. That Social Security deduction is the Part B premium — $202.90/month in 2026, up from $185 in 2025, a $17.90 monthly increase. That amount is your baseline Medicare cost and continues regardless of which Aetna plan — or any other Medicare Advantage plan — you’re enrolled in. For most single seniors with household income at or below $109,000 (2024 MAGI), the standard $202.90 applies. Income above that threshold triggers IRMAA surcharges, potentially pushing your Part B premium from $284.10 all the way to $689.90 per month. If you recently sold a home, converted retirement accounts, or had other large income events, check whether IRMAA applies to you at ssa.gov.

How much does Medicare cost at age 65? Part A: $0 for most people (40+ quarters of Medicare-taxed work) · Part B: $202.90/month standard · Part D drug plan (standalone): ~$35–$60/month average if not bundled · Medicare Advantage (Part C) like Aetna: often replaces Parts A, B, D together with possible $0 additional premium · Original Medicare + Medigap Plan G + Part D: typically $388–$458/month total · Medicare Advantage route: often $202.90/month total if a $0 premium plan is available at your addressAt 65, Medicare splits into different pieces that you can combine in two main ways. The Original Medicare path keeps you in the federal program and pairs Parts A and B with a standalone Part D drug plan and an optional Medigap supplement that covers the 20% Original Medicare doesn’t pay. This path typically costs $388–$458 per month for Part B plus Plan G plus Part D, with broader provider access but no extra benefits. The Medicare Advantage path — where Aetna operates — replaces Original Medicare with a private plan that bundles everything (often including dental, vision, hearing, and Part D) and can cost as little as $202.90/month total if a $0-premium Aetna plan is available in your county. The important trade-off: Medicare Advantage restricts you to a network, while Original Medicare lets you see any provider that accepts Medicare in the entire country.

Is Aetna a good supplemental insurance for seniors? Aetna offers two separate Medicare products that often get confused · Aetna Medicare Advantage (Part C): replaces Original Medicare entirely — not a supplement · Aetna Medicare Supplement (Medigap): works alongside Original Medicare to cover the 20% cost-share gap — this IS a supplement · For Medigap: Aetna offers standardized plans (Plan G, Plan N) but UnitedHealthcare is typically $40–$60/month cheaper for the same Medigap benefits in most states · For Medicare Advantage: Aetna earns a weighted CMS Star Rating of 4.2 — among the highest of major carriersThe word “supplemental” creates confusion because Aetna sells both types of Medicare coverage. Medigap (Medicare Supplement) is a specific product that sits on top of Original Medicare — you keep Original Medicare as your primary coverage, and your Medigap policy pays most or all of the 20% coinsurance that Original Medicare leaves to you. Aetna sells Medigap plans, but in most states, UnitedHealthcare’s Medigap is $40–$60/month cheaper for identical standardized benefits under the same federal rules. For Medicare Advantage — the Part C replacement product — Aetna’s 4.2 weighted star rating from CMS puts it above the national average. NerdWallet specifically calls out Aetna’s strong quality scores as a key advantage. But Aetna does get below-average marks on customer satisfaction surveys, which is worth weighing if ease of dealing with insurance claims matters to you.

Which is better — Blue Cross or Aetna for seniors? Blue Cross Blue Shield: varies dramatically by state because each BCBS affiliate is independently operated — quality, network, and costs differ significantly from state to state · Aetna: more nationally consistent with CVS Health integration, ~4.2 weighted CMS stars · BCBS is stronger in states with high-performing affiliates (Michigan, Minnesota) · Aetna is stronger in the Northeast, Mid-Atlantic, and Florida · The comparison only makes sense at your specific address — compare plans at medicare.gov by entering your ZIP codeThe Blue Cross vs. Aetna question doesn’t have a universal answer because “Blue Cross Blue Shield” isn’t one company — it’s a federation of independent regional insurers (Anthem, Highmark, CareFirst, BCBS of Michigan, and dozens more) operating under the BCBS brand. A BCBS plan in Michigan might earn 4.5 stars while a BCBS plan in a different state earns 3.5 stars, and both appear as “Blue Cross” to you. Aetna, by contrast, operates under one company structure with CVS Health’s resources behind it. The CVS connection is a meaningful differentiator: Aetna members can access over 1,000 CVS MinuteClinic locations for routine care, often at $0 copay, and get preferred pricing at CVS pharmacies. If you use CVS regularly or live near CVS locations, that integration can be worth more in practical value than the star rating alone.

Who is better — UnitedHealthcare or Aetna for Medicare? UnitedHealthcare: available all 50 states (vs Aetna’s 43), largest Medicare Advantage enrollment, generally better pricing on Medigap policies · Aetna: higher CMS Star Ratings on Medicare Advantage (4.2 weighted vs UHC’s 4.10), CVS pharmacy integration, $0 MinuteClinic copays · For Medigap: UHC wins on price in most states by $40–$60/month · For Medicare Advantage: Aetna wins on star quality scores; UHC wins on geographic coverage · For people who use CVS regularly: Aetna’s pharmacy integration offers practical advantages UHC doesn’t matchBoth are legitimate, large carriers — the real question is which one has better plans available at your specific address and covers your specific doctors. UnitedHealthcare’s national footprint (all 50 states vs. Aetna’s 43) means it’s the only option in some rural areas where Aetna doesn’t operate. For Medigap policies specifically, UHC consistently comes in cheaper — sometimes $40–$60/month less for the same Plan G or Plan N coverage, which adds up to $480–$720/year. For Medicare Advantage, Aetna’s weighted CMS star rating advantage is measurable but not dramatic. The CVS integration is Aetna’s clearest differentiator — walk-in MinuteClinic access at $0 copay, preferred pharmacy pricing, and 24/7 telehealth through CVS Health Virtual Care are benefits no other major Medicare Advantage carrier currently replicates at the same scale.

How do I find my Aetna copay for a specific service? Copays vary by plan type, plan tier, and specific service — there is no universal Aetna copay chart · Primary care: typically $0 on most plans · Specialist: $20–$50 depending on plan · Emergency care: $90–$130 · Hospital inpatient: $375–$450 per admission on many plans · Tier 1 generics: $0 at preferred pharmacies on 91% of Aetna plans · Tier 2 generics: $0 on 91% of plans · Official source: your specific plan’s Evidence of Coverage document, available at aetna.com or by calling the member number on your cardThe only place that has your actual copay for a specific service under your specific plan is your plan’s Evidence of Coverage (EOC) document. That document — usually 200+ pages — lists every service, every copay, every coinsurance percentage, and every authorization requirement for your exact plan. You can find it at aetna.com under “Plan Documents” or by calling the member services number on the back of your Aetna insurance card. For prescription drugs specifically, Aetna’s formulary (drug list) shows what tier each medication falls into and what you’ll pay at each tier. NerdWallet’s analysis found that 91% of Aetna Medicare Advantage plans have $0 copays on Tier 1 and Tier 2 generic drugs at preferred pharmacies, which is a consistent strength. For specialty drugs in Tier 4 and Tier 5, expect significant cost-sharing until you hit the $2,100 annual drug cap — after which all covered drugs are $0 for the rest of the year.

How much is Medicare Part C per month? Medicare Part C (Medicare Advantage) plan premium: $0 to $204/month for Aetna plans · Industry-wide average: ~$143/month for all MA plans, but Aetna and most large carriers have many $0-premium options · Part C does not replace your Part B premium — you still owe $202.90/month · Total monthly cost: Part B + Part C plan premium (which may be $0) + any drug or service copaysPart C is the official Medicare name for Medicare Advantage. When you enroll in Part C through a carrier like Aetna, you’re not buying something extra on top of Original Medicare — you’re replacing Original Medicare with a private insurance plan that must cover everything Medicare Parts A and B cover, and usually more. The monthly cost of the Part C plan itself (the plan premium) is what Aetna charges above and beyond what Medicare already deducts for Part B. For many Aetna plans, that additional charge is $0. For PPO plans with broader network flexibility, it can reach $204/month. The Part B premium ($202.90 in 2026) continues regardless. So your total monthly Medicare cost when enrolled in Aetna Part C is: $202.90 (Part B) + your specific Aetna plan premium (often $0) + whatever copays and deductibles you incur during the month.

How much is Medicare for high income earners? IRMAA surcharges apply to singles earning above $109,000/year (2024 income) or couples above $218,000 · Part B premium range: $202.90 to $689.90/month depending on income bracket · Part D IRMAA surcharge: $14.50 to $91.00/month additional · Highest combined monthly Medicare cost (Part B + Part D IRMAA): up to $780.90/month before any plan costs · These surcharges are based on your 2024 tax return — regardless of what your income is todayThe IRMAA surcharge is the Medicare cost that surprises high-income seniors most, because it hits before you’ve made any plan choices. If your 2024 Modified Adjusted Gross Income exceeded $109,000 as a single filer, your 2026 Part B premium is automatically higher than the standard $202.90 — and the surcharge is applied per person, meaning a married couple both on Medicare each pays the higher amount individually. The surcharge is calculated on a five-bracket scale. At the very top bracket (income above $500,000 for single filers or $750,000 for joint filers), the Part B premium reaches $689.90/month per person. One important protection: if your income dropped recently due to retirement, death of a spouse, or divorce, you can appeal the IRMAA by filing Form SSA-44 with the Social Security Administration to request a reduction based on your current income rather than the two-year-old figure CMS uses by default.
Aetna offers three main plan structures. Your county determines which ones are available at your address. Costs shown are representative ranges — always verify your specific plan at aetna.com.

|---|---|---|---|
| CMS Star Rating (avg) | 4.2 weighted (MA) | 4.10 weighted | Varies by affiliate (3.5–4.5+) |
| States available | 43 + DC | All 50 + DC | All states (varies by region) |
| $0 premium availability | 82% of service areas | Many markets | Varies by affiliate |
| Unique advantage | CVS/MinuteClinic integration | Broadest national network | Strong local provider relationships |
| Medigap price vs Aetna | Standard (higher in most states) | Often $40–$60/month cheaper | Varies by state affiliate |
| Customer satisfaction | Below-average in surveys | Average | Varies by affiliate |
| $0 generic drugs | 91% of plans at CVS preferred pharmacy | Many plans | Varies by plan |

For Medicare Advantage: Aetna leads on star quality scores and offers the CVS integration advantage no other carrier can match. UnitedHealthcare leads on geographic reach and plan availability. BCBS quality is entirely local — check specifically what’s available in your county, not what the brand is. For Medigap: UnitedHealthcare is generally cheaper for the same standardized benefits. The best strategy is to run your specific ZIP code through the Medicare Plan Finder at medicare.gov and compare what’s actually available at your address, then check which plan covers your specific doctors and prescriptions.
Maybe — and the “maybe” is important. Every Aetna Medicare Advantage plan has a formulary listing covered drugs by tier. Tier 1 (generic) and Tier 2 (preferred generic) drugs are covered at $0 on 91% of Aetna plans at CVS preferred pharmacies. Higher-tier drugs — specialty biologics for conditions like rheumatoid arthritis, cancer, or MS — can cost several hundred dollars per fill until you hit the $2,100 annual out-of-pocket drug cap. Once you hit $2,100 total in drug costs for the year, those drugs are $0 for the rest of that calendar year. The practical step before enrolling in any plan: go to medicare.gov, use the Plan Finder, and enter every medication you take by name. The tool shows you the projected annual drug cost under each plan — often revealing that a plan with a higher monthly premium charges less for your specific medications than a $0-premium plan with a more restrictive formulary. Also ask about Aetna’s Medicare Prescription Payment Plan, which spreads your drug costs in equal monthly payments interest-free across the year rather than hitting large costs all at once.
You have three paths. First: consider switching your care to an in-network provider who’s new to you — uncomfortable but often more practical than people expect, especially if your current relationship with your doctor is routine rather than long-established. Second: choose the Aetna PPO instead of HMO — the PPO lets you see out-of-network providers with a larger cost share rather than no coverage at all. Your out-of-pocket costs will be higher than for in-network care, but you won’t be paying full retail price. Third: compare other carriers at medicare.gov — your doctor may be in UnitedHealthcare’s network, or a BCBS affiliate’s network, when they’re not in Aetna’s HMO network. Before enrolling in any plan, verify every doctor, specialist, and hospital you regularly use by name in that plan’s provider directory. This one step prevents the most common and costly Medicare Advantage mistake.
- Part B premium jumped to $202.90 in 2026 — up $17.90 from $185 in 2025. If you were budgeting based on last year’s Part B amount, your monthly Medicare cost is already $17.90 higher regardless of your Aetna plan selection.
- The drug out-of-pocket cap increased to $2,100 — up slightly from $2,000 in 2025. After reaching $2,100 in covered drug costs, all covered prescriptions are $0 for the rest of the year.
- Drug deductible maximum: $615 — this applies to Tier 3 and above drugs on plans that have a deductible. Tier 1 and Tier 2 generics are typically exempt from this deductible on most Aetna plans.
- MinuteClinic integration expanded — Aetna’s CVS ownership means broader MinuteClinic access for routine care, vaccinations, and health screenings, increasingly at $0 copay on more plan types.
- Aetna is offering a $0-premium plan in every county where it operates — confirming availability has stayed consistent even as other carriers have reduced $0-premium offerings in some markets.
This is the most important cost comparison most seniors never run. Original Medicare pays 80% of most covered services — you pay 20% indefinitely, with no annual cap. A senior who has surgery, extended hospital stays, or frequent specialist visits under Original Medicare without a Medigap supplement can face tens of thousands of dollars in 20% cost-share bills with no ceiling. Medicare Advantage plans including Aetna’s have a hard out-of-pocket maximum — ranging from well under $4,000 on some Aetna HMO plans to up to $9,350 on PPO plans. Once you hit that ceiling, covered in-network services cost you nothing for the rest of the year. For a senior who needs significant healthcare in a given year, Aetna’s maximum (even a high one) may be far lower than the unlimited 20% exposure of Original Medicare without a Medigap supplement. Original Medicare with a Plan G supplement and Part D drug coverage closes the cost gap — but typically costs $388–$458/month total versus often $202.90/month for a $0-premium Aetna plan. The right answer depends on your specific health use, your preferred doctors, and whether Aetna’s network in your county covers the providers you need.
SHIP advisors in every state offer free, unbiased Medicare counseling — no sales pressure, no commission. Use the buttons below to find local help with Aetna plan comparisons, enrollment, and cost questions.
- Confirm your doctors are in-network. Go to aetna.com and search the specific plan’s provider directory for every physician, specialist, and hospital you use regularly. For HMO plans, being out-of-network means paying full price — not a higher cost share. This single step prevents the most expensive Medicare Advantage mistake.
- Enter your prescriptions into the Medicare Plan Finder. At medicare.gov, the Plan Finder tool calculates your estimated annual drug cost under every available plan. A $0-premium plan often has higher drug costs for your specific medications than a plan with a small monthly premium — only the calculator reveals the true total cost.
- Look at the out-of-pocket maximum, not just the premium. A plan with a $0 premium and a $9,350 MOOP provides far less catastrophic protection than a plan with a $30 premium and a $3,500 MOOP. The MOOP is the ceiling on your financial exposure — it matters more than the monthly premium for seniors with significant health needs.
- Check whether IRMAA applies to you. If your 2024 income (as a single filer) exceeded $109,000, your Part B premium is higher than $202.90 before you make any plan choice. If it applies to you and your income has since dropped due to retirement, file Form SSA-44 to appeal for a reduction based on current income rather than the two-year-old figure CMS uses automatically.
- Call SHIP for a free second opinion. State Health Insurance Assistance Programs provide no-cost, no-commission Medicare counseling in every state. A 30-minute call with a SHIP advisor can surface options and cost comparisons that a carrier’s own agents have no incentive to show you. Find your local SHIP at shiphelp.org or call 1-800-MEDICARE.
