Aetna's 2027 Medicare Advantage lineup in Las Vegas: one plan gone, one new, four renamed

Las Vegas, fall 2026 — Aetna's Medicare Advantage menu for Clark County is set for 2027, and most of the movement this year is in the names on the paperwork rather than the size of the lineup. Aetna (which CMS lists as Aetna (CVS Health)) will offer 11 Medicare Advantage plans in the county next year — the same count as 2026 — but one plan is not coming back, one is brand new, and four are being renamed. If you are already in an Aetna plan here, that means the plan card in your wallet may read differently in January even if your coverage largely carries over.

MyMedicarePlans.org is an independent consumer site, not Aetna and not Medicare. Aetna is one of 10 carriers selling Medicare Advantage in Clark County for 2027, and together those carriers offer 72 plans. This article walks through Aetna's slice of that market so you can check it against your own doctors and prescriptions before the December 7, 2026 deadline.

What Medicare Advantage plans does Aetna offer in Las Vegas for 2027?

Aetna offers 11 Medicare Advantage plans in Clark County, the county Las Vegas is in, for the 2027 plan year. Seven are HMOs and four are PPOs. Ten include Part D prescription drug coverage; one does not. Two are Dual Eligible Special Needs Plans (D-SNPs) for people with both Medicare and Medicaid, and one is a Chronic Condition Special Needs Plan (C-SNP).

The table below lists every Aetna plan available in the county for 2027, with its type and whether it includes drug coverage. Plan names are shown exactly as CMS lists them.

What is new or not returning in Aetna's 2027 lineup?

One Aetna plan sold in Clark County in 2026 is not being offered again in 2027, and one plan is new: Aetna Medicare Full Dual (HMO D-SNP), a Dual Eligible Special Needs Plan with drug coverage.

Four plans are being renamed for 2027. The new names, with what they were called in 2026, are:

• Aetna Medicare Partial Dual (HMO D-SNP) — was Aetna Medicare Dual Prime (HMO D-SNP)
• Aetna Medicare Prime (HMO) — was Aetna Medicare Prime Extra (HMO)
• Aetna Medicare Prime Extra (HMO) — was Aetna Medicare Prime (HMO)
• Aetna Medicare Signature (HMO) — was Aetna Medicare Signature Extra (HMO)

Because two of the renames swap the "Prime" and "Prime Extra" labels, read your Annual Notice of Change (ANOC) carefully — the plan you are enrolled in for 2026 may not match the 2027 plan that now carries the same name. Your ANOC lists the specific benefit, cost and network changes for your plan.

What are Special Needs Plans, and which does Aetna sell here?

Special Needs Plans (SNPs) are Medicare Advantage plans built for people with specific situations. Aetna offers three in Clark County for 2027: two D-SNPs — Aetna Medicare Full Dual (HMO D-SNP) and Aetna Medicare Partial Dual (HMO D-SNP) — and one C-SNP, Aetna Medicare Chronic Care (HMO C-SNP).

D-SNPs are for people who qualify for both Medicare and Medicaid. C-SNPs are for people with certain chronic conditions. To enroll in a SNP, you must meet the eligibility rules for that plan; the carrier will verify this.

What happens if I do nothing before December 7, 2026?

If you take no action, your current plan renews on January 1, 2027 as described in its Annual Notice of Change — as long as the plan is being offered again. If your plan is one that is not returning, Medicare will send you a non-renewal notice and you will have a Special Enrollment Period to pick a new plan.

The Annual Enrollment Period runs October 15 through December 7, 2026. Changes made during that window take effect January 1, 2027. There is also a Medicare Advantage Open Enrollment Period from January 1 through March 31, 2027, which lets people already in a Medicare Advantage plan make a one-time switch.

What 2027 Medicare figures have been confirmed, and what has not?

CMS has confirmed several Part D figures for 2027. The Part D out-of-pocket cap will rise to $2,400 in 2027 (up from $2,100 in 2026). The Part D maximum deductible will be $700 in 2027 (up from $615 in 2026). The Part D national base beneficiary premium for 2027 is $41.33 — that is a formula input used across the program, not what any specific plan charges.

The 2027 Part B standard premium and deductible have not been announced yet. CMS typically releases those figures later in the fall, usually in November, along with the 2027 IRMAA income brackets and surcharges. For reference, in 2026 IRMAA surcharges begin above $109,000 in income for a single filer.

The coverage gap, often called the "donut hole," was eliminated starting in 2025, so Part D now has three phases. The Medicare Prescription Payment Plan remains available as an option to spread drug costs across the year in level monthly amounts.

How do I check an Aetna plan against my doctors and prescriptions before December 7?

Use the Plan Finder at Medicare.gov or call 1-800-MEDICARE (available 24/7). Enter your ZIP code and your current medications, and the tool will show which plans cover them and at what tier. To confirm a doctor or hospital is in network, check the plan's provider directory or call the member services number on the plan page.

A good checklist before you pick:

1. Pull your current prescription list, including dosages. 2. List the doctors, specialists and hospitals you want to keep. 3. Read your 2026 plan's ANOC to see what is changing. 4. Compare on Medicare.gov, not on any one carrier's own site. 5. If anything is unclear, call 1-800-MEDICARE or the plan directly.

Networks, formularies and costs can change year to year, so a plan that fit in 2026 may fit differently in 2027.
