Key takeaways
- 14 Medicare Advantage plans offered in Idaho in 2026 are not in the CMS 2027 file for any Idaho county, from Humana, Molina Healthcare of Utah & Idaho, PacificSource Medicare, Saint Alphonsus Health Plan, and UnitedHealthcare.
- If your plan is on the list, your carrier must mail you a non-renewal notice, and you can compare 2027 options during Annual Enrollment, October 15 – December 7, 2026.
- Doing nothing means you return to Original Medicare on January 1, 2027, with no Part D drug coverage unless you choose a plan.
- A Special Enrollment Period runs through the end of February 2027 for members of non-renewed plans, and a federal Medigap guaranteed-issue right may also apply.
| Fact | Figure | Source |
|---|---|---|
| Part B standard monthly premium (2026) | $202.90 | Medicare.gov |
| Part D out-of-pocket cap (2026) | $2,100 | CMS |
| Part D out-of-pocket cap (2027) | $2,400 | CMS |
| Annual Enrollment Period (for 2027 coverage) | October 15 – December 7, 2026 | Medicare.gov |
| Medicare Advantage Open Enrollment Period | January 1 – March 31 | Medicare.gov |
Area counts are for the county as a whole and are not a recommendation of any plan. Program figures are set nationally.
If one of the 14 plans is yours, you have time and options. If it isn't, nothing on this list changes your coverage. Either way, the Annual Enrollment Period runs October 15 – December 7, 2026, and the choice you make during Annual Enrollment 2027 takes effect January 1, 2027.
Which Medicare Advantage plans are not returning in Idaho for 2027?
Fourteen plans offered in Idaho for 2026 are not in CMS's 2027 Landscape file for any Idaho county. They come from five carriers: Humana, Molina Healthcare of Utah & Idaho, PacificSource Medicare, Saint Alphonsus Health Plan, and UnitedHealthcare.
By carrier, the exits are: Humana Essentials Plus Giveback H5216-429 (PPO) and HumanaChoice – Diabetes and Heart (PPO C-SNP) from Humana; two Molina Medicare Complete Care Select (HMO D-SNP) listings from Molina Healthcare of Utah & Idaho; PacificSource Medicare Explorer 6 (PPO), PacificSource Medicare MyCare Choice 30 (HMO-POS), PacificSource Medicare MyCare Choice Rx 24 (HMO-POS), and PacificSource Medicare MyCare Choice Rx 34 (HMO-POS) from PacificSource Medicare; Saint Alphonsus Health Plan Cash Back (HMO), Choice (PPO), Glory No RX (HMO), and No Premium (HMO) from Saint Alphonsus Health Plan; and AARP Medicare Advantage from UHC ID-0010 (PPO) and ID-0011 (PPO) from UnitedHealthcare. The full list is shown in the table on this page.
Which non-returning Idaho plans served the most counties in 2026?
The non-returning plan with the widest 2026 footprint in Idaho is Molina Medicare Complete Care Select (HMO D-SNP), listed with 38 counties served this year. Behind it, PacificSource Medicare Explorer 6 (PPO) served 15 counties and AARP Medicare Advantage from UHC ID-0011 (PPO) served 13 counties, as did PacificSource Medicare MyCare Choice Rx 24 (HMO-POS).
A plan is offered county by county, so the county counts above describe where a plan was sold in 2026, not where any individual reader lives. If the plan name on your member ID card is not on this list, your plan is not among the Idaho exits.
How can I tell if my Idaho Medicare Advantage plan is leaving in 2027?
There are two reliable signals. First, if your plan is being discontinued, your carrier is required to mail you an Annual Notice of Non-Renewal, generally arriving in October. Second, you can match the plan name on your member ID card, exactly, against the list of 14 plans on this page.
Spelling matters because carriers often sell several plans with similar names. For example, Saint Alphonsus Health Plan lists four exiting plans — Cash Back (HMO), Choice (PPO), Glory No RX (HMO), and No Premium (HMO) — and only the exact names on the list are the ones not returning.
What happens to Idaho members who do nothing by December 7, 2026?
If your plan is non-renewed and you make no other choice, you will be returned to Original Medicare (Part A and Part B) on January 1, 2027. You will not have Medicare Part D prescription drug coverage unless you actively enroll in a stand-alone Part D plan or a Medicare Advantage plan that includes drug coverage.
Original Medicare pays a defined share of covered services, and the extras some Medicare Advantage plans include are not part of it. That is why members of the 14 non-returning plans are generally encouraged to make an active choice rather than let the default happen.
What is the Special Enrollment Period and Medigap right for a non-renewed plan?
Members of a Medicare Advantage plan that is non-renewed qualify for a Special Enrollment Period that runs through the end of February 2027, in addition to the Annual Enrollment Period that ends December 7, 2026. During that window you can join another Medicare Advantage plan or move to Original Medicare with a stand-alone Part D plan.
At the federal program level, losing your Medicare Advantage plan because it is leaving the service area also triggers a Medigap (Medicare Supplement) guaranteed-issue right, which lets you buy certain Medigap policies without medical underwriting within a limited window. State rules can expand on this; for Idaho-specific Medigap questions, the Idaho Department of Insurance is the authority.
How do I check my own Idaho county's 2027 Medicare Advantage lineup?
The official county-level view comes from the Medicare Plan Finder at medicare.gov, which uses the CMS Landscape Source File. Enter your ZIP code to see every Medicare Advantage and Part D plan available where you live for 2027.
You can also call 1-800-MEDICARE (1-800-633-4227), 24 hours a day, seven days a week, to confirm what is offered in your county and whether your current plan appears for 2027.
What should Idaho members do before December 7, 2026?
Three practical steps help before December 7, 2026. First, check whether your plan name appears on the list of 14 non-returning plans on this page. Second, if it does, read the non-renewal letter from your carrier and gather your prescriptions, pharmacies, and doctors. Third, compare the 2027 plans available in your county on medicare.gov or by phone.
Keep in mind that the 44 Medicare Advantage plans CMS lists for Idaho in 2027 are not all offered in every county; availability still depends on where you live.
Where can Idahoans get free Medicare help?
Free, unbiased help is available directly from Medicare. Call 1-800-MEDICARE (1-800-633-4227), any day, any hour, or use the Plan Finder and account tools at medicare.gov.
For Social Security questions tied to Medicare — enrollment in Part A and Part B, premium billing, and Extra Help with drug costs — contact the Social Security Administration at ssa.gov or 1-800-772-1213.
