Medicare Advantage
Does Aetna offer a new Indianapolis plan for 2027?
INDIANAPOLIS — Fall 2026. Aetna will offer five Medicare Advantage plans in Marion County for 2027, one more than it offered this year. The new addition is a Chronic Condition Special Needs Plan, and none of Aetna's current Indianapolis plans are leaving for next year. If you already have an Aetna plan, your Annual Notice of Change (ANOC) spells out what is different for 2027 — and you have until December 7, 2026 to make a change that takes effect January 1.

What Aetna Medicare Advantage plans are available in Indianapolis for 2027?
Aetna is offering 5 Medicare Advantage plans in Marion County — the county Indianapolis is in — for 2027. The breakdown by type is 2 HMOs and 3 PPOs, and all 5 include Part D prescription drug coverage. Two of the HMOs are Chronic Condition Special Needs Plans (C-SNPs), designed for people with specific long-term conditions; Aetna is not offering a Dual Eligible SNP or Institutional SNP in the county for 2027.
The full list of Aetna plans in the county for 2027, in alphabetical order:
- Aetna Medicare Chronic Care (HMO C-SNP) — with drug coverage — new for 2027
- Aetna Medicare Chronic Care Total (HMO C-SNP) — with drug coverage
- Aetna Medicare Eagle (PPO) — with drug coverage
- Aetna Medicare Signature (PPO) — with drug coverage
- Aetna Medicare Value Care (PPO) — with drug coverage
The table on this page shows every plan Aetna is offering in the county. We cannot publish premiums, copays, deductibles, networks, drug lists or star ratings for any of them — those are personal to each plan and have to be checked on the official Medicare Plan Finder.
What is new or not returning from Aetna in Marion County for 2027?
One Aetna plan is new in Marion County for 2027: Aetna Medicare Chronic Care (HMO C-SNP). No Aetna plans in the county are leaving for next year, and none have been renamed.
Special Needs Plans like C-SNPs are only open to people who have a qualifying chronic condition (for example, diabetes or certain heart conditions). The specific conditions each C-SNP covers are listed in the plan's Evidence of Coverage; if you think a C-SNP may fit, call Medicare or check the Plan Finder to confirm you qualify.
If you are already enrolled in one of Aetna's returning plans — Chronic Care Total, Eagle, Signature or Value Care — your 2027 coverage is a continuation of your current plan, not a new policy. The ANOC Aetna mailed in September tells you what is changing on January 1.
How do I check an Aetna plan against my doctors and prescriptions before December 7?
The fastest way is the Medicare Plan Finder at medicare.gov. Enter your ZIP code (or log in with your Medicare account), add your prescriptions and preferred pharmacy, and the tool will show how each plan covers your drugs and estimate your yearly cost. For doctors and hospitals, use the plan's provider directory on Aetna's site, or call the number on the plan's page to confirm a specific provider is in-network for the 2027 plan year — networks can shift from one year to the next.
If you prefer the phone, 1-800-MEDICARE (TTY 1-877-486-2048) is open 24/7 and can walk you through the same comparison. Have your Medicare number and a list of your prescriptions handy.
A quick checklist before December 7, 2026:
- Pull out your Annual Notice of Change and read what is different for 2027.
- Confirm your primary doctor, any specialists you see, and your preferred pharmacy are in-network.
- Check that your prescriptions are on the plan's 2027 formulary (and at what tier).
- If you take expensive drugs, look into the Medicare Prescription Payment Plan, which lets you spread Part D out-of-pocket costs across the year.
What else should Indianapolis residents know for the 2027 plan year?
The Annual Enrollment Period runs October 15 through December 7, 2026, and any change you make takes effect January 1, 2027. If you do nothing, your current plan renews as described in its ANOC. There is also a Medicare Advantage Open Enrollment Period from January 1 – March 31, 2027, when people already in an MA plan can switch to a different MA plan or go back to Original Medicare one time.
A few 2027 figures CMS has already confirmed and that apply nationwide:
- The Part D out-of-pocket cap rises to $2,400 in 2027 (up from $2,100 in 2026).
- The Part D maximum deductible is $700 in 2027 (up from $615 in 2026).
- The Part D national base beneficiary premium is $41.33 for 2027 — that is a formula input, not what any specific plan charges.
CMS has not yet announced the 2027 Part B standard premium and deductible or the 2027 IRMAA income brackets; those are typically published in November.
Aetna is one of 11 carriers offering Medicare Advantage in Marion County for 2027, and all carriers together offer 79 plans in the county. If an Aetna plan does not fit your doctors or drugs, there are other options to compare on the Plan Finder.
