Medicare Advantage

How to Sort Through Medicare Choices in Rockville Centre

Rockville Centre sits in Nassau County, where people turning 65 or reviewing their coverage this fall have a wide field of Medicare options to weigh for 2027. For 2026, Nassau County has 66 Medicare Advantage plans available and 15 carriers offering Medicare Advantage with drug coverage; the 2027 lineup is detailed in each plan's Annual Notice of Change and on Medicare.gov's Plan Finder. With roughly 259,500 residents age 65 and older across the county, that is a lot of neighbors doing the same homework at the same time.

The point of this guide is not to tell you which plan to pick — that is personal — but to help you understand what "options" really means, so the count feels less overwhelming and more like a menu you can navigate.

What "66 plans" really means

That 66 is the number of Medicare Advantage plans a Nassau County resident could shop from during enrollment. It is a county-level count set by the Centers for Medicare & Medicaid Services (CMS), so a Rockville Centre address and a Hempstead address see the same list.

You will not choose from all 66. Once you filter by the doctors you want to keep, the medicines you take, and the extras that matter to you, the realistic short list is usually much smaller — often a handful.

The other Medicare paths on the menu

Medicare Advantage is only one road. Your other main options as a Rockville Centre resident are:

• Original Medicare (Parts A and B) directly through the federal program.
• Original Medicare plus a Medigap (Medicare Supplement) policy, often paired with a stand-alone Part D drug plan.
• Medicare Advantage (Part C), which bundles hospital, medical, and usually drug coverage through a private carrier.

One quirk worth noting: for 2026, CMS listed 0 stand-alone Part D plans specifically tied to the Nassau County MA landscape file, but stand-alone Part D plans for New York State are still available and searchable on medicare.gov's Plan Finder. If you go the Original Medicare + Medigap route, that is where you would shop for drug coverage; the 2027 lineup is on Plan Finder as well.

How carriers and plans differ

Fifteen carriers offer Medicare Advantage with drug coverage in the area. Each carrier typically sells more than one plan, which is how you get to 66 total. Plans from the same carrier can differ in network size, drug formulary, and included extras, so two plans with similar names are not interchangeable.

When you compare, focus on four questions:

1. Are my doctors and preferred hospitals in the network? 2. Are my prescriptions on the plan's formulary, and at what tier? 3. What is the total yearly cost picture — premium, deductible, copays, and the plan's out-of-pocket maximum? 4. Does the plan include extras I will actually use?

What Star Ratings are — and are not

CMS publishes Star Ratings (1 to 5) each year to measure plan quality on things like customer service and preventive care. They are a useful data point, not a verdict. A high rating does not mean a plan fits your prescriptions or your doctor; a lower rating does not automatically mean poor care. Use ratings as one factor alongside network and drug coverage.

Key 2026 and 2027 program facts to keep in mind

These apply nationwide, no matter which plan you land on:

• Part D out-of-pocket spending is capped at $2,100 in 2026.
• The Part D maximum deductible is $615.
• The old coverage gap ("donut hole") is gone as of 2025 — Part D now has three phases.
• The Medicare Prescription Payment Plan lets you spread drug costs across the calendar year in monthly installments instead of paying big amounts at the pharmacy counter.
• IRMAA income-based premium surcharges begin above $109,000 for a single filer in 2026.

Important dates

• October 15 – December 7: Annual Enrollment Period. You can join, switch, or drop a Medicare Advantage or Part D plan. Changes take effect January 1.
• January 1 – March 31: Medicare Advantage Open Enrollment. If you are already in an MA plan, you get one chance to switch to another MA plan or return to Original Medicare.

Where to get unbiased help

With 66 plans on the shelf, most people benefit from talking to someone who is not selling anything:

• medicare.gov — the official Plan Finder lets you enter your ZIP code and prescriptions.
• 1-800-MEDICARE — available 24/7.
• New York's SHIP, called HIICAP (Health Insurance Information, Counseling and Assistance Program) — free one-on-one counseling for Nassau County residents.
