Aetna's 2027 Medicare Advantage lineup in San Antonio: two new plans, four renamed

San Antonio, fall 2026 — Aetna's Medicare Advantage menu in Bexar County is shifting for 2027. The carrier is offering 11 Medicare Advantage plans in the county next year, up from 9 this year, with two brand-new plans, four that have been renamed, and none pulled from the market. If you already have an Aetna plan here, your Annual Notice of Change (ANOC) is the single most important piece of mail you'll get this fall — and the Annual Enrollment Period runs October 15 through December 7, 2026, for coverage that starts January 1, 2027.

MyMedicarePlans.org is an independent consumer site. We are not Aetna, and Aetna is one of 15 carriers offering Medicare Advantage plans in Bexar County for 2027 (98 plans in all). This article walks through Aetna's slate so you can check it against your own doctors and prescriptions before December 7.

How many Aetna Medicare Advantage plans are offered in San Antonio for 2027?

Aetna is offering 11 Medicare Advantage plans in Bexar County — the county San Antonio sits in — for the 2027 plan year. That's up from 9 Aetna plans in 2026. All 11 include Part D prescription drug coverage.

By plan type, the 2027 Aetna lineup breaks down as 8 HMOs and 3 PPOs. Four are Dual Eligible Special Needs Plans (D-SNPs) for people who have both Medicare and Medicaid, and two are Chronic Condition Special Needs Plans (C-SNPs) for people with qualifying long-term conditions. Aetna has no Institutional SNPs (I-SNPs) in the county for 2027.

Plan availability is set at the county level by CMS, so these counts describe Bexar County — not just the city limits.

Which Aetna plans are new, renamed, or leaving Bexar County for 2027?

Two Aetna plans are new in Bexar County for 2027, four are renamed versions of 2026 plans, and none of Aetna's 2026 plans are leaving the county.

The two new plans are:

• Aetna Medicare Chronic Care Total (HMO C-SNP)
• Aetna Medicare QMB Only Care (HMO D-SNP)

The four renamed plans — same plan structure under a new name — are:

• Aetna Medicare Chronic Care (HMO C-SNP), formerly Aetna Medicare Prime Chronic Care (HMO C-SNP)
• Aetna Medicare Full Dual Care (HMO D-SNP), formerly Aetna Medicare Dual Care (HMO D-SNP)
• Aetna Medicare Full Dual Extra Care (HMO D-SNP), formerly Aetna Medicare Full Dual Care (HMO D-SNP)
• Aetna Medicare QMB Only Extra Care (HMO D-SNP), formerly Aetna Medicare Partial Dual Care (HMO D-SNP)

A renamed plan can still have changes to its benefits, network or formulary from one year to the next. Your Annual Notice of Change — mailed by late September — spells out exactly what is different in your specific plan for 2027.

How do Special Needs Plans in the Aetna lineup work?

A Special Needs Plan is a Medicare Advantage plan built for people who meet certain eligibility rules. Aetna offers two kinds in Bexar County for 2027: D-SNPs and C-SNPs.

• D-SNPs (Dual Eligible Special Needs Plans) are for people enrolled in both Medicare and Medicaid. Aetna has four D-SNPs in the county for 2027. Which one you qualify for depends on your specific Medicaid category, which Texas Medicaid determines.
• C-SNPs (Chronic Condition Special Needs Plans) are for people with a qualifying chronic condition. Aetna has two C-SNPs in the county for 2027. You usually need your doctor to verify the condition.

If you aren't sure whether you're eligible for a SNP, 1-800-MEDICARE and your plan's member services line can both walk you through it.

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

Before you pick or renew any plan, run it through the Medicare Plan Finder at medicare.gov — it's the official tool, it's free, and it checks your drugs and pharmacy against each plan's formulary in Bexar County.

A short checklist that works for any plan on this list:

1. Gather your list. Write down every prescription (name, dose, how often), the pharmacies you use, and the doctors and hospitals you want to keep. 2. Use Plan Finder. Enter your ZIP code and drugs at medicare.gov/plan-compare. It will show you the plans available in Bexar County and estimate your yearly drug costs under each one. 3. Check the provider directory. Each plan has its own network. Confirm your primary care doctor, specialists and preferred hospitals are in-network for the specific plan you're considering — not just "Aetna" in general. 4. Read the ANOC. If you already have an Aetna plan, your Annual Notice of Change lists what's different for 2027. Even a renamed plan can have changes. 5. Call if you're stuck. 1-800-MEDICARE (TTY 1-877-486-2048) is available 24/7, and the plan's member services number is on your card.

Nothing has to happen on your side for coverage to continue — if you do nothing, your current plan renews for 2027 if it's still offered, with the changes described in your ANOC. The December 7, 2026 deadline matters only if you want to switch, drop or add a plan for January 1.

What 2027 Medicare figures are already confirmed?

A few program-level numbers for 2027 are already set by CMS and apply no matter which plan you pick:

• Part D out-of-pocket cap: $2,400 in 2027 (up from $2,100 in 2026). Once your out-of-pocket drug spending hits that cap, you pay $0 for covered Part D drugs for the rest of the year.
• Part D maximum deductible: $700 in 2027 (up from $615 in 2026). Individual plans can set a lower deductible.
• Part D national base beneficiary premium: $41.33 for 2027. This is a formula input CMS uses — it is not what any particular plan charges.
• Medicare Prescription Payment Plan: still available in 2027, letting you spread out-of-pocket drug costs across monthly payments instead of paying at the pharmacy counter.

CMS has not yet announced the 2027 Part B standard premium and deductible or the 2027 IRMAA income brackets. Those usually come out in the fall, often in November. We'll update our coverage when they're published.
