Which Idaho Medicare plans are ending in 2027?

Checked October 6, 2026 against CMS's 2026 and 2027 plan lists and September 2026 enrollment.

The biggest plans ending: Trinity Health (22,891 members), SilverScript (18,054 members), PacificSource (17,066 members). CMS's 2027 Plan Crosswalk says 29 Idaho Medicare Advantage and Part D plans end or leave counties for 2027, with at least 84,463 people enrolled who must choose a new plan. Another 1 plans (1,547 people) were merged into other plans or given new plan numbers; CMS moves those members automatically, and their letter names the new plan. A plan that ends stops on December 31, 2026. It does not mean you lose Medicare. Your plan's own letter is the final word.

Medicare Advantage plans available in Idaho for 2027

Checked 2026-10-17 against CMS's 2027 plan benefit and county files.

44 Medicare Advantage plans are offered in Idaho for 2027 by 8 companies. 28 are HMO plans and 16 are PPO plans. 11 are special needs plans, which only people who qualify (for example, people who also have Medicaid or a chronic condition) can join, so 33 are open to most people with Medicare. Depending on the county, you can choose from between 3 and 27 plans.

Compared with 2026: 48 plans were offered in Idaho in 2026, so the count is down by 4 for 2027. New to Idaho for 2027: Range Health (3 plans), St. Luke's Health Plan (3 plans). Listed in CMS's 2026 files but not its 2027 files: Saint Alphonsus Health Plan (4 plans in 2026). A company can also appear to leave because it changed its name, so check your own plan's letter.

Ready to enroll in a Idaho plan?

Call 855-367-1095 to enroll

No cost. No obligation. Not the government. Speak with a licensed insurance agent (TTY 711).

Will a 2027 plan keep your doctors and cover your prescriptions?

The public plan sites can't tell you that without a lot of clicking, and some 2027 plans aren't on them until October 15. Give us your doctors and your prescriptions and a licensed agent checks every 2027 plan in your county against your list, then calls you with the two or three that fit. No cost, no obligation.

Got a letter saying your Medicare plan is leaving or won't renew?

A non-renewal letter means your specific plan won't continue in your county after December 31, 2026. It doesn't mean you lose Medicare, and it usually doesn't mean your insurance company is leaving Medicare altogether. You can choose a new Medicare Advantage plan, or move to Original Medicare with a Medigap plan and a Part D drug plan.

Medicare Advantage in Idaho today

At least 178,192 Idaho residents are in an individual Medicare Advantage plan (46 plans from 7 companies across 44 counties in 2026).
Largest carriers by members: UnitedHealthcare (74,611), Blue Cross of Idaho (36,019), Saint Alphonsus Health Plan (22,891), PacificSource Medicare (17,066), Humana (14,510), Molina Healthcare (12,845).
Last year, 31 Idaho Medicare Advantage plans ended or dropped counties for 2026, affecting about 98,809 members, most from Blue Cross of Idaho, UnitedHealthcare, Regence.

My Medicare Advantage plan is ending. What are my deadlines?

Your current plan keeps working through December 31, 2026. Doctors, prescriptions and benefits work as usual until then.
Open Enrollment, October 15, 2026 to December 7, 2026: pick a new plan now and it starts January 1, 2027, with no gap.
Your extra window, December 8, 2026 to February 28, 2027: because your plan is being discontinued, you get a Special Enrollment Period on top of Open Enrollment. An enrollment request received December 8-31 is effective January 1; received in January, effective February 1; received in February, effective March 1.
Medigap guaranteed issue: apply as early as November 1, 2026, and no later than March 4, 2027 (63 days after your coverage ends).

What happens if I do nothing when my plan is cancelled?

You don't lose Medicare. If you don't choose a new plan, you're moved to Original Medicare (Parts A and B) on January 1, 2027. Original Medicare doesn't include prescription drug coverage, so you'd need to join a separate Part D plan. Going 63 days or more without creditable drug coverage can mean a permanent late-enrollment penalty.

Can I switch to a Medicare Supplement (Medigap) plan without health questions?

Usually yes. When a Medicare Advantage plan leaves your area or stops offering coverage, federal law gives you a guaranteed issue right: a Medigap company must sell you Plan A, B, D or G (or C or F if you were eligible for Medicare before January 1, 2020), can't charge more for past or present health problems, and can't refuse you, as long as you switch to Original Medicare. Some states add more rights than this. Keep your non-renewal letter; it can serve as proof.

Questions about Idaho Medicare plans ending

Which Medicare Advantage plans are ending in Idaho for 2027?

The list on this page comes straight from CMS's 2027 plan files: every plan that won't renew, or won't be offered in a county, in Idaho. It covers several carriers.

Is my Medicare Advantage plan being cancelled in Idaho?

If your plan won't continue, you'll get a non-renewal letter by October 2, 2026. Your Annual Notice of Change (ANOC) lists what's changing if your plan does continue. Your plan stays in force through December 31, 2026 either way.

How many people in Idaho lost their Medicare Advantage plan last year?

For 2026, CMS's files show 31 Medicare Advantage plans ended or dropped counties in Idaho, affecting about 98,809 members across 38 counties.

What happens if I don't pick a new plan after my Medicare Advantage plan ends?

You don't lose Medicare. If you don't choose anything, you're moved to Original Medicare (Parts A and B) on January 1, 2027. Original Medicare doesn't include drug coverage, so you'd need to join a separate Part D plan, and going 63 days or more without creditable drug coverage can mean a late-enrollment penalty.

How long do I have to switch after my Medicare Advantage plan is discontinued?

You can switch during Open Enrollment, October 15, 2026 to December 7, 2026, for coverage starting January 1. Because your plan is ending, you also get a Special Enrollment Period from December 8, 2026 through February 28, 2027. An enrollment request received December 8-31 is effective January 1; received in January, effective February 1; received in February, effective March 1. Choosing by December 7, 2026 avoids any gap.

Can I get a Medicare Supplement (Medigap) plan without health questions if my plan is ending?

Usually yes. When a Medicare Advantage plan leaves your area or stops offering coverage, you have a guaranteed issue right to buy Medigap Plan A, B, D or G (and C or F if you were eligible for Medicare before January 1, 2020) without medical underwriting, as long as you move to Original Medicare. You can apply as early as 60 days before your coverage ends and no later than 63 days after (March 4, 2027). Some states give more rights than this.

Why did I get a letter saying my Medicare plan won't renew?

Plans that won't continue next year must mail members a non-renewal notice by October 2, 2026. It means your current plan ends December 31, 2026, not that you lose Medicare. Keep the letter: it shows which plan is ending and helps prove your enrollment rights.

Will my doctors still be covered on a new plan in Idaho?

It depends on the plan you choose. Before switching, check that your doctors, specialists and hospitals are in the new plan's network, your prescriptions are on its drug list, and your pharmacy is covered. With Original Medicare plus Medigap, you can see any provider that accepts Medicare.

Which Medicare Advantage plans are available in Idaho for 2027?

CMS's 2027 files list 44 Medicare Advantage plans offered in Idaho by 8 companies: UnitedHealthcare (15 plans), Humana (10 plans), Blue Cross of Idaho (8 plans), Range Health (3 plans), St. Luke's Health Plan (3 plans), and others. 11 of them are special needs plans, which only people who qualify can join. Which plans you can actually choose depends on your county.

I just found out my plan is ending. Do I need to decide right away?

No. Your plan works through December 31, 2026. You can choose a new plan from October 15 to December 7, and because your plan is ending you also get a Special Enrollment Period from December 8 through February 28, 2027. Deciding earlier just means your new plan is settled before January 1.

Will I get pressured into a sales call if I ask for help?

No. A licensed agent looks at the plans available where you live in Idaho, explains what changes for you, and you decide. There is no cost to you and no obligation to enroll in anything. Calls are recorded, as Medicare requires.

How do I know my plan is on this list?

Type your plan name or the plan ID from your member card into the box above the table. The list comes from CMS's own 2026 and 2027 plan files. Your plan's written notice is the final word; if the two disagree, trust the letter and have a licensed agent check it with you.
