A Look at Medicare Plan Availability Around Waterloo

A Look at Medicare Plan Availability Around Waterloo — plain-language Medicare information for Waterloo, Iowa.

WATERLOO, Iowa — If you're turning 65 soon or already on Medicare, you've probably wondered how many choices are actually out there in your corner of the Cedar Valley. The short answer: quite a few. Waterloo sits in Black Hawk County, where 32 Medicare Advantage plans were available in the 2026 landscape, according to CMS Plan Finder and Landscape data. The 2027 lineup is described in each plan's Annual Notice of Change and on Medicare.gov's Plan Finder. That's the county-level backdrop for the roughly 23,138 residents age 65 and older who live here.

This piece isn't a ranking or a shopping list. It's a plain look at what's on the menu near Waterloo, plus the program rules everyone on Medicare should know heading into 2027.

What "plan availability" means around Waterloo

Medicare Advantage and Part D availability is set by CMS at the county level, not the city. So when we say Waterloo had 32 Medicare Advantage plans in the 2026 landscape, what we really mean is that Black Hawk County — where Waterloo, Cedar Falls, Evansdale and Hudson all sit — had 32 MA plans listed for 2026. The 2027 count is in each plan's ANOC and on Medicare.gov's Plan Finder.

Seven carriers offer Medicare Advantage plans with prescription drug coverage (MA-PD) in the area. Having multiple carriers matters because each one builds its own doctor and hospital network, so the "right" plan for a neighbor may not be the right one for you.

A note on stand-alone Part D

One thing worth flagging on the drug-coverage side: Iowa has 11 stand-alone Part D plans for 2026, sold statewide, so anyone in Black Hawk County on Original Medicare can choose from that same statewide list. Stand-alone Part D plans are the drug-only plans people typically pair with Original Medicare (Parts A and B) or a Medigap policy.

If you rely on Original Medicare and want drug coverage, this is a good year to double-check availability directly on medicare.gov's Plan Finder or by calling 1-800-MEDICARE, because the landscape can shift and your options depend on your ZIP code.

What Star Ratings tell you (and what they don't)

CMS gives every Medicare Advantage and Part D contract a Star Rating from 1 to 5, based on things like customer service, member complaints, and how well the plan manages chronic conditions. It's a quality signal, not a price tag.

Under CMS's 2026 Star Ratings, 8 of the 13 Medicare Advantage contracts offering plans in Black Hawk County are rated 4 stars or higher. That said, ratings can move year to year, some newer contracts aren't rated yet, and stars are only one piece of the picture. Your doctors, your prescriptions, and your budget matter just as much.

Program rules to know for 2026 and 2027

A few program-wide facts to keep in your back pocket:

• Part D out-of-pocket cap: $2,100 in 2026 and $2,400 in 2027. Once you hit that amount for the year, you pay $0 for covered drugs the rest of the year.
• Part D deductible: No plan can charge more than $615 in 2026, or more than $700 in 2027.
• The "donut hole" is gone. As of 2025, Part D moved to three simpler phases — deductible, initial coverage, and catastrophic.
• Medicare Prescription Payment Plan: An optional way to spread your drug costs across the calendar year in monthly installments instead of paying big amounts at the pharmacy counter.
• IRMAA: Higher-income beneficiaries pay a surcharge on Part B and Part D premiums. For 2026, that starts above $109,000 in income for a single filer.

Dates to circle

• Annual Enrollment Period (AEP): Oct. 15 – Dec. 7. This is when almost everyone can change Medicare Advantage or Part D coverage for the following year.
• Medicare Advantage Open Enrollment Period: Jan. 1 – March 31. If you're already in a Medicare Advantage plan, you get one chance during this window to switch to another MA plan or drop back to Original Medicare.
