Turning 65 in Boise County, ID: Your 2027 Medicare Checklist

Turning 65 comes with a stack of mail, a few hard deadlines and one big choice. The deadlines are the same everywhere in Idaho. The choice is not: the Medicare Advantage plans you can buy depend on your county, and Boise County has its own short list for 2027. This checklist is the Boise County version. For the full statewide walk-through, read our Turning 65 in Idaho checklist or the month-by-month Learning Center guide.

Why Turning 65 Matters So Much in Boise County

Boise County is one of the older counties in Idaho. More than one resident in four is already 65 or older, and another one in ten is between 60 and 64, which means a lot of Idaho City, Horseshoe Bend, Garden Valley, Placerville, Crouch and Lowman neighbors are reaching Medicare age over the next few years.

In practice that means you probably know someone who just went through this. Their advice is worth hearing, but check one thing before you copy their plan: whether they live in Boise County too, and whether that plan is still sold for 2027. Seven Medicare Advantage plans with drug coverage that were sold in Boise County in 2026, two of them Special Needs Plans, do not continue for 2027, according to the CMS 2027 plan crosswalk.

Your Enrollment Dates

Your Initial Enrollment Period is seven months long: the three months before the month you turn 65, your birthday month, and the three months after. If you sign up in the first three months, your coverage starts on the first day of your birthday month. Sign up later in the window and coverage starts the month after you sign up (Medicare.gov, when coverage starts). Here is how that plays out for three 2027 birthdays.

Source: rules from Medicare.gov, When does Medicare coverage start?, applied to the dates shown. If your birthday is on the 1st of the month, every date moves one month earlier.

Missing the window can cost you for life: Medicare adds a late enrollment penalty to Part B and Part D premiums if you go without coverage you needed (Medicare.gov, late enrollment penalties). The main exception is when you, or your spouse, are still working with group coverage from that job. That is worth a phone call before you decide; our answer on working at 65 covers the basics.

The Boise County Checklist

1. Six months out: decide about work coverage. If you or your spouse are still working, find out whether that employer plan works with Medicare or expects you to take Part B. Bring that answer to us.
2. Three months out: sign up for Parts A and B. Enrollment goes through Social Security (Medicare.gov, how to sign up). If you already collect Social Security benefits, you are usually enrolled automatically and your card comes in the mail.
3. Make your list. Every prescription with the dose, your pharmacy, and every doctor and clinic you want to keep, whether they are in Boise County or down in the Treasure Valley. Plans in Boise County use different networks, and that list decides more than anything else.
4. Choose your path. Original Medicare with a Medigap policy and a Part D plan, or a Medicare Advantage plan. We break that choice down for Boise County in Medicare Advantage or Medigap in Boise County.
5. Mind the Medigap window. Your Medigap open enrollment period lasts six months, starting the month you are 65 or older and have Part B. During it, a company cannot turn you down or charge you more because of your health (Medicare.gov, Choosing a Medigap Policy). After it, health questions can apply.
6. Pick drug coverage you will not regret in January. Price your actual drug list, not just the premium.
7. Sign the Scope of Appointment and meet with us. Medicare requires a short Scope of Appointment form before we talk about specific plans. Then we compare and you decide.

The 2027 Medicare Advantage Plans Sold in Boise County

CMS lists 14 Medicare Advantage plans for Boise County in 2027, not counting Special Needs Plans, from 3 carriers. 10 have a $0 Part C premium, 9 include Part D drug coverage, and in-network out-of-pocket maximums run from $3,000 to $9,150 (CMS 2027 Landscape file). There are also 7 Special Needs Plans for people with Medicaid or certain chronic conditions.

Here is the full list, grouped by carrier. A $0 premium does not make a plan the right one, and a star rating is CMS's score for the contract, not a promise about your doctors. It is a starting point.

The plan list for Boise County is shorter than the list in Ada County, and it changed for 2027. If you are turning 65 this year, start from the 2027 list, not from what a neighbor picked in 2025.

The 2027 Numbers, Released and Pending

Some 2027 Medicare figures are official and some are not out yet. We only publish what CMS has released.

Standalone Part D premiums in Idaho run from $5.30 to $238 a month for 2027 (CMS 2027 Landscape file). Our 2027 Part D guide lists every one of them.
