HMO or PPO? Idaho Medicare Advantage for 2027: 28 HMO Plans, 16 PPO

BOISE, Idaho — Idahoans comparing Medicare Advantage for the coming plan year will see a familiar question at the top of every brochure: HMO or PPO? According to the CMS Medicare Advantage Landscape Source File for CY2027, Idaho has 44 Medicare Advantage plans from 8 carriers for 2027, split 28 HMO-family plans (15 HMO plus 13 HMO-POS) and 16 PPO plans. Which plans actually appear on your doorstep depends on your county.

How does Idaho's 2027 Medicare Advantage lineup split by plan type?

Idaho has 44 Medicare Advantage plans for 2027 across 8 carriers, divided into 15 HMO plans, 13 HMO-POS plans and 16 PPO plans, per the CMS Landscape Source File. Counting the HMO family together — standard HMO plus HMO-POS — the state has 28 HMO-type plans and 16 PPO plans for 2027.

That is a close split, and it is a statewide count. A plan is approved to serve specific counties, so the mix you can actually choose from in Ada, Kootenai, Bonneville, Nez Perce or Bear Lake County will be a subset of the 44. The full lists by type are rendered as tables on this page.

What do HMO, HMO-POS, PPO and PFFS mean for networks, referrals and out-of-network care in Idaho?

These letters describe how the plan handles doctors and hospitals, and they are the single biggest structural difference between Medicare Advantage plans.

• HMO (Health Maintenance Organization): You generally use in-network providers, often pick a primary care physician, and may need a referral to see a specialist. Out-of-network care is typically covered only in emergencies.
• HMO-POS (Point of Service): An HMO with a "point of service" option that allows some out-of-network care under defined rules.
• PPO (Preferred Provider Organization): You can see in-network and out-of-network providers, usually without a referral, though in-network care is handled differently from out-of-network care by the plan.
• PFFS (Private Fee-for-Service): A separate category where providers decide visit by visit whether to accept the plan's terms. The CMS 2027 landscape for Idaho lists HMO, HMO-POS and PPO plans in the counts above.

The rules that apply to your specific plan — including how referrals and out-of-network claims work — live in that plan's Evidence of Coverage and provider directory.

Which carriers offer HMO, HMO-POS and PPO plans in Idaho for 2027?

For 2027, eight carriers participate in Idaho's Medicare Advantage market across the three plan types.

• HMO carriers: American Health Advantage of Utah, Blue Cross of Idaho, Humana, Molina Healthcare of Utah & Idaho, and St. Luke's Health Plan.
• HMO-POS carriers: PacificSource Medicare and UnitedHealthcare.
• PPO carriers: Blue Cross of Idaho, Humana, Range Health, and UnitedHealthcare.

Some carriers appear in more than one category because they file multiple plan types with CMS. The county-by-county tables on this page show which of these plans are actually offered where you live.

How do I decide whether an HMO or PPO fits my doctors and travel in Idaho for 2027?

Start with two lists: the doctors, clinics and hospitals you want to keep, and the places you spend meaningful time outside your home county. Then match them to the plan type.

If every provider you care about is inside one health system and you rarely travel for care, an HMO or HMO-POS can be a clean fit — provided those providers are in that plan's network. If you split time between, say, the Treasure Valley and a second home in another state, see out-of-area specialists, or want the flexibility to go out of network without a referral, a PPO's structure may matter more to you.

Two cautions. First, "PPO" does not automatically mean a provider will accept the plan; always confirm with the office. Second, networks and service areas can change each year, so a plan that fit in 2026 should still be re-checked for 2027 on the Medicare Plan Finder at medicare.gov.

What should Idaho Medicare beneficiaries do before December 7, 2026?

The Annual Enrollment Period for 2027 coverage runs October 15 – December 7, 2026, and a choice made during that window takes effect January 1, 2027. A short checklist helps:

1. Read the Annual Notice of Change your current plan mailed in September 2026 for the 2027 plan year. 2. List your prescriptions, your regular providers, and the pharmacies you use. 3. Run your list through the Medicare Plan Finder at medicare.gov to see which 2027 plans are offered in your county and how they handle your drugs and providers. 4. Confirm plan type — HMO, HMO-POS or PPO — and read the referral and out-of-network rules in the plan's Evidence of Coverage. 5. Make your decision by December 7, 2026.

Doing nothing is also a choice: in most cases your current plan rolls into its 2027 version, with whatever changes the Annual Notice of Change describes.

Where can Idahoans get free help comparing 2027 Medicare Advantage plans?
