Aetna Medicare Advantage in Delaware for 2027: 6 Plans, County by County

DOVER, Del. — For the 2027 plan year, Aetna (which CMS groups as Aetna (CVS Health)) is bringing six Medicare Advantage plans to Delaware, according to the federal government's Medicare Advantage Landscape Source Files for CY2027. Those plans sit inside a wider statewide field of 38 Medicare Advantage plans from eight carriers in all. This article, from an independent Medicare education site that is not the government and not affiliated with Aetna or any other insurance carrier, walks through what Aetna is offering in Delaware next year, how to tell if a given plan reaches your county, and what the calendar looks like between now and the January 1, 2027 effective date.

What is Aetna offering across Delaware for 2027?

Aetna has 6 Medicare Advantage plans in Delaware for the 2027 plan year: 5 HMOs and 1 PPO. Within those six, 2 are Chronic Condition Special Needs Plans (C-SNPs), designed for people living with certain qualifying chronic conditions. Aetna is not offering a Dual Eligible SNP (D-SNP) or an Institutional SNP (I-SNP) in Delaware for 2027.

Five of the six plans include Part D prescription drug coverage built in; one does not. The full plan-by-plan breakdown appears in the table on this page, including each plan's type and whether it carries drug coverage. For context, Delaware's 2027 Medicare Advantage landscape totals 38 plans from eight carriers, including Aetna; Aetna is one voice in that field, not the whole conversation.

Which Aetna Delaware plans reach the most counties in 2027?

All six of Aetna's 2027 Delaware plans are listed in 3 counties — which, in a three-county state (New Castle, Kent and Sussex), means each plan's service area is filed statewide at the county level. The plans are: Aetna Medicare Advantra Eagle Plus (HMO), Aetna Medicare Advantra Signature (HMO), Aetna Medicare Chronic Care (HMO C-SNP), Aetna Medicare Chronic Care Total (HMO C-SNP), Aetna Medicare Enhanced (HMO), and Aetna Medicare Premier (PPO).

A county-level filing in the CMS Landscape file does not guarantee that every doctor, hospital or pharmacy in that county participates with a given plan. The service area tells you where you may enroll; the plan's own provider directory and Evidence of Coverage tell you who is in network and what is covered.

What is new or not returning from Aetna in Delaware for 2027?

For 2027, Aetna is adding 1 new Medicare Advantage plan in Delaware and ending 1 plan that was offered in 2026. The new entrant for 2027 is Aetna Medicare Enhanced (HMO), which is listed in all three Delaware counties and includes drug coverage.

If you are currently enrolled in an Aetna plan that is not continuing into 2027, you should receive an Annual Notice of Change (ANOC) from Aetna explaining what is happening and your options. That notice typically arrives in the fall before Annual Enrollment 2027 opens. Reading it carefully is the simplest way to see whether your current plan is one of the five Aetna plans continuing in Delaware, the one new plan, or the one that is going away.

How do I check whether an Aetna plan is offered in my Delaware county and covers my doctors and drugs?

The fastest way to confirm availability in New Castle, Kent or Sussex County is the Medicare Plan Finder at medicare.gov, which lets you enter your ZIP code and see every Medicare Advantage plan filed in your county for 2027, including Aetna's. You can also call 1-800-MEDICARE (1-800-633-4227), which is open 24 hours a day, seven days a week.

For doctors, hospitals and specialists, use the plan's provider directory — not a general web search — because networks are plan-specific and can change year to year. For prescriptions, use the plan's formulary (drug list), checking each medication by name, dosage and tier. The Evidence of Coverage document for each plan is the authoritative source for benefits, cost-sharing, prior authorization rules and appeal rights. Those details are not reproduced in this article.

What should I do in Delaware before December 7, 2026?

Annual Enrollment 2027 runs October 15 – December 7, 2026, and any plan choice made in that window takes effect January 1, 2027. Before December 7, 2026, three steps tend to be the most useful: read your ANOC if you already have a Medicare Advantage or Part D plan; make a short list of your current doctors, hospitals and prescriptions; and run that list against any plan you are considering using the Plan Finder.

The December 7, 2026 date is a calendar deadline, not a sales deadline. If you are happy with your current coverage and it is continuing into 2027, you generally do not have to do anything to stay in it. If your plan is ending or changing in ways that no longer fit, Annual Enrollment 2027 is the window to switch.

Where can Delaware residents get free help comparing 2027 Medicare plans?

Two free, official resources are available to anyone in New Castle, Kent or Sussex County. The first is medicare.gov, where the Plan Finder lists every Medicare Advantage and Part D plan available in your ZIP code for 2027, with the ability to enter your drugs and preferred pharmacies. The second is 1-800-MEDICARE (1-800-633-4227), which is staffed 24/7 and can walk you through enrollment, disenrollment and plan comparisons.

For questions specific to one of Aetna's six Delaware plans — a benefit, a copay, a network question, a star rating or a formulary tier — contact Aetna directly using the member or prospective-member number on the plan's materials, or review the plan's Evidence of Coverage.
