Portsmouth Medicare 2026: 16 Advantage Plans in Rockingham

PORTSMOUTH, N.H. — If you're sorting through your Medicare choices for 2026, here's a plain look at what's on the table locally. Portsmouth is in Rockingham County, where the Centers for Medicare & Medicaid Services (CMS) shows 16 Medicare Advantage plans available for the coming year. That's the count of options — not a ranking, and not a recommendation.

Portsmouth Seniors Have 16 Medicare Advantage Plans to Choose From in 2026

For a county with more than 65,000 residents age 65 and older, that mix of choices matters. Knowing how many plans are out there — and where they come from — is the first step to making a calm, informed decision.

What the Numbers Look Like in Rockingham County

Here's the snapshot for the Portsmouth area, drawn from CMS's 2026 Medicare Advantage and Part D landscape data:

• Medicare Advantage plans available: 16
• Carriers offering Medicare Advantage with drug coverage (MA-PD): 4
• Stand-alone Part D drug plans available: 0 (see note below)
• Contracts rated 4 stars or higher in the area: 0
• Population 65+ in the county: 65,026

A quick note on that "0" for stand-alone Part D: stand-alone drug plans are actually sold by CMS region, not by county, so New Hampshire residents do have Part D options through the regional market. The county-level count above simply reflects how the local landscape file is drawn. When you shop on medicare.gov, you'll see the full list of stand-alone drug plans available to you by ZIP code.

Why "How Many" Isn't the Same as "Which One"

Sixteen is a manageable number, but it's still a lot to sift through if you're comparing them one by one. Every plan has its own network of doctors and hospitals, its own drug formulary, and its own rules for referrals and prior authorization.

The count tells you the size of the menu. It doesn't tell you which plan fits your prescriptions, your providers, or your budget. That part takes a closer look — ideally with the Plan Finder tool at medicare.gov or with free help from a trained counselor (more on that below).

A Few 2026 Program Facts Worth Knowing

These apply nationwide, no matter which plan you're looking at:

• Part D out-of-pocket cap: $2,100 in 2026. Once your out-of-pocket spending on covered drugs hits that ceiling, you pay nothing more for covered prescriptions the rest of the year.
• Part D maximum deductible: $615.
• No more "donut hole." As of 2025, Part D has three phases instead of four. The coverage gap is gone.
• Medicare Prescription Payment Plan. This optional program lets you spread your drug costs into monthly payments across the year instead of paying big amounts at the pharmacy counter.
• IRMAA (income-related premium surcharges) begin above $109,000 in income for single filers in 2026.

Star Ratings, Explained

You'll see CMS Star Ratings (1 to 5 stars) attached to plans on medicare.gov. They're a quality measure — CMS looks at things like customer service, member complaints, and how well plans manage chronic conditions.

In the Portsmouth area, no contracts currently carry a 4-star or higher rating for 2026. Ratings can change year to year, and they're one data point among many. They're not a substitute for checking whether your doctors and drugs are covered.

Key Dates to Circle

• Annual Enrollment Period (AEP): October 15 – December 7. This is when most people can join, switch, or drop a Medicare Advantage or Part D plan for the following year.
• Medicare Advantage Open Enrollment: January 1 – March 31. If you're already in a Medicare Advantage plan, you get one chance during this window to switch to a different MA plan or return to Original Medicare.

Miss these windows and you may have to wait a full year unless you qualify for a Special Enrollment Period.
