Medicare in Nampa: 32 Plan Choices in Canyon County for 2026

NAMPA, Idaho — If you're turning 65 soon or thinking about switching plans this fall, here's the short version: you have a lot of options to sort through. Nampa is in Canyon County, where 32 Medicare Advantage plans were offered for the 2026 plan year, according to CMS Medicare Plan Finder data. The 2027 lineup is detailed in each plan's Annual Notice of Change and on Medicare.gov's Plan Finder.

Nampa seniors have plenty of Medicare choices for 2027

That's a healthy menu of choices — and for many people, it's more than they expected. The goal of this article isn't to point you toward any one plan. It's to help you understand how many options you're actually choosing between, and how to narrow them down without losing a weekend to spreadsheets.

What the numbers look like in Canyon County

Here is the plan landscape for the area around Nampa in 2026:

• 32 Medicare Advantage plans available in Canyon County
• 7 carriers offering Medicare Advantage with prescription drug coverage (MA-PD) in the area
• 36,467 residents age 65 and older live in Canyon County

Stand-alone Part D drug plans aren't counted in that 32 — those are a separate product for people who stay on Original Medicare and want drug coverage added on. Availability for stand-alone Part D is set regionally, so your options there come from a different list on Medicare.gov.

Star Ratings are also worth mentioning briefly. CMS rates Medicare Advantage and Part D contracts on a 1-to-5 scale based on things like customer service and care quality. Ratings can change year to year, so it's worth checking the current numbers on Medicare.gov when you compare.

Why 32 plans is a lot — and how to shrink the list

Thirty-two plans sounds overwhelming until you realize most people can rule out the majority in about 15 minutes. Here's a simple way to narrow things down:

1. Start with your doctors. If keeping your current primary care provider or specialist matters, check which plan networks they're in. That alone often cuts the list in half. 2. List your prescriptions. Every plan has its own drug formulary. Type your medications into Medicare Plan Finder and it will show which plans cover them. 3. Think about how you use care. If you travel a lot, or split time between Idaho and another state, network rules matter more. If you rarely leave the Treasure Valley, that's less of a concern. 4. Consider Original Medicare + Medigap as an alternative. Medicare Advantage isn't the only path. Some Nampa retirees prefer Original Medicare with a Medigap (Medicare Supplement) policy and a stand-alone Part D plan.

The Part D rules that apply no matter which plan you pick

A few program-level facts are worth knowing before you shop. These come from CMS and apply nationwide:

• Part D out-of-pocket cap: $2,100 in 2026 and $2,400 in 2027. Once your out-of-pocket spending on covered drugs hits that amount in a year, you pay nothing more for covered prescriptions the rest of that year.
• Part D maximum deductible: $615 for 2026 and $700 for 2027. Plans can charge less, but not more.
• No more "donut hole." The old coverage gap was eliminated in 2025. Part D now has three phases instead of four.
• Medicare Prescription Payment Plan. This optional program lets you spread your drug costs across the calendar year in monthly payments instead of paying at the pharmacy counter.
• IRMAA. Higher-income beneficiaries pay an income-related surcharge on Part B and Part D premiums. For 2026, IRMAA begins above $109,000 in income for a single filer.

The dates you can't miss

• Annual Enrollment Period: October 15 – December 7, 2026. This is when most people join, switch, or drop a Medicare Advantage or Part D plan for 2027.
• Medicare Advantage Open Enrollment: January 1 – March 31. If you're already in a Medicare Advantage plan and want to switch to a different one — or go back to Original Medicare — you get one more chance here.

Missing these windows can leave you locked into a plan for a full year, so put them on the calendar.
