Idaho Has 8 Health Insurance Carriers — More Than Most Small States
Idaho’s individual market features 8 carriers — Blue Cross of Idaho, Regence Blue Shield, SelectHealth, Mountain Health CO-OP, Molina, Moda, PacificSource, and St. Luke’s — offering 154 medical and 21 dental plans through Your Health Idaho for 2026. That’s a high count for a state of 2 million: Montana has 3 carriers, Wyoming has 2. More competition means lower prices — one reason 87% of Idaho enrollees received tax credits in 2025.
The eight carriers fall into three categories. Two offer PPO plans with broad provider networks and out-of-network coverage: Blue Cross of Idaho and Regence Blue Shield of Idaho. Three offer HMO or EPO plans with lower premiums but restricted networks: Mountain Health CO-OP, Molina Healthcare, and Moda Health Plan. And three offer a mix of plan types that varies by county: SelectHealth (PPO and HMO), PacificSource (POS), and St. Luke’s Health Plan (HMO tied to the St. Luke’s hospital system). Knowing which health insurance companies in Idaho serve your area is the first step toward finding the best health insurance in Idaho — and the best health insurance in Idaho for one county may not be available in the next.
Not all eight carriers serve every county. The Boise metropolitan area (Ada, Canyon, and Gem counties) typically has the most carrier options — often six to eight. Rural eastern Idaho counties may have three or four, and the panhandle (Kootenai, Bonner, Boundary counties) sits between the two. Checking yourhealthidaho.org with a specific zip code shows exactly which carriers and plans are available in a given area. Quality ratings from NCQA’s Health Plan Report Cards can also help compare carrier performance.

Why PPO Plans Matter More in Idaho Than Most States
Idaho is the 14th largest state by area but ranks 39th in population — meaning large distances between population centers and medical facilities. PPO plans let Idaho residents see any provider without a referral, including specialists and hospitals outside their home region. For residents in rural counties where the nearest specialist may be in Boise, Pocatello, or Salt Lake City, the ability to go out-of-network can be the difference between accessible care and a 200-mile drive.
Three Idaho carriers offer PPO plans: Blue Cross of Idaho (all 44 counties), Regence Blue Shield (most counties), and SelectHealth (select counties). PPO plans typically cost more per month than HMO plans — but for many Idahoans searching for the best health insurance in Idaho, the flexibility justifies the premium difference. Consider the geography: Idaho stretches 479 miles from the Canadian border to Nevada, and many rural counties have one hospital and limited specialists. The federal plan type definitions from HealthCare.gov explain how PPO, HMO, and POS networks are structured nationwide.
The State of Idaho itself chose a Regence PPO for its state employee health plan in July 2024 — the most popular option among state workers, with roughly 22,700 enrolled (about 85% of the state employee population) per Idaho Capital Sun reporting. That’s a practical endorsement of the PPO model for a workforce spread across all 44 Idaho counties. Regence administers this plan as part of the Cambia Health Solutions family, which serves Idaho, Oregon, Washington, and Utah.
PPO plans also provide out-of-state coverage through national Blue Cross Blue Shield networks. Idaho shares borders with 6 states — Oregon, Washington, Montana, Wyoming, Utah, and Nevada — and communities like Lewiston (population 33,000, near Pullman, WA), Montpelier (near Logan, UT), and Sandpoint (near Spokane, WA, 75 miles north) regularly access healthcare across state lines. Roughly 32 of Idaho’s 44 counties border another state, giving the best health insurance in Idaho a strong cross-border use case.

PPO vs. HMO vs. POS: Choosing the Right Plan Type in Idaho
PPO plans cost more per month but offer unrestricted provider choice and out-of-network coverage. HMO plans have lower premiums but require referrals and limit care to in-network providers. POS plans split the difference — lower in-network costs with limited out-of-network access. For Idahoans researching the best health insurance in Idaho, the choice often comes down to geography: Boise metro residents with multiple in-network options can save with an HMO, while rural residents benefit from PPO flexibility.
PPO Plans
Referral needed? No
Out-of-network? Yes, at higher cost
Idaho carriers: Blue Cross of Idaho, Regence, SelectHealth
Silver avg (age 40): ~$552/month
Best for: Rural residents, specialist access, cross-state care, provider choice
HMO Plans
Referral needed? Yes (for specialists)
Out-of-network? No (except emergencies)
Idaho carriers: Mountain Health CO-OP, Molina, St. Luke’s, SelectHealth
Silver avg (age 40): ~$520/month
Best for: Budget-conscious, urban residents with strong in-network options
POS Plans
Referral needed? Sometimes
Out-of-network? Limited
Idaho carriers: Moda, Regence, PacificSource
Silver avg (age 40): ~$503–565/month
Best for: Balance of cost and flexibility; only option for Platinum tier in Idaho
Example: Rural vs. Urban Decision
Maria in Boise (Ada County): Has six carriers available, three major hospital systems within 15 miles, and rarely needs specialists outside her area. An HMO from Mountain Health CO-OP or Molina saves her $30–50/month over a comparable PPO — and she’ll almost never need out-of-network access. Best choice: HMO.
David in Salmon (Lemhi County): Has two carriers available. The nearest cardiologist is in Idaho Falls (160 miles) or Missoula, Montana (150 miles). An HMO would require him to find an in-network cardiologist — which may not exist within reasonable driving distance. A Blue Cross of Idaho PPO lets him see any provider, including across state lines. Best choice: PPO.
Compare Idaho Health Insurance Plans
Comparing the best health insurance in Idaho means seeing 2026 PPO, HMO, and POS plans from all 8 Your Health Idaho carriers. Bronze starts at $349/month (St. Luke’s), Silver averages $481/month, and 87% of Idaho enrollees received tax credits averaging roughly $407/month in 2025 (KFF).
What PPO Plans Cost in Idaho for 2026
PPO premiums in Idaho range from approximately $385–$440/month for Bronze to $900–$1,100/month for Gold, depending on carrier and age. For a 40-year-old, a Silver PPO from SelectHealth averages $552/month before subsidies, while Blue Cross of Idaho Silver plans range from $481 to $565/month. The premium difference between PPO and HMO at the Silver tier is roughly $30–50/month for the same age — the cost of provider flexibility.
| Plan Type | Silver Premium (Age 40) | Typical Deductible | Out-of-Pocket Max |
|---|---|---|---|
| PPO — SelectHealth | $552/month | $3,000 | $9,900 |
| PPO — Blue Cross of Idaho | $481–$565/month | $4,500–$6,300 | $8,700–$9,100 |
| HMO — Molina | $520/month | $6,250 | $9,280 |
| HMO — Mountain Health CO-OP | ~$510/month | $5,500 | $9,100 |
| POS — Moda | $565/month | $4,533 | $8,200 |
| POS — Regence | $503/month | $4,200 | $8,700 |
An important nuance when shopping the best health insurance in Idaho: PPO plans often have lower deductibles than HMO plans. The SelectHealth Silver PPO has a $3,000 deductible compared to Molina’s Silver HMO at $6,250. That means the PPO enrollee pays less out of pocket before insurance kicks in — partially offsetting the higher monthly premium. Over a year, a PPO enrollee who uses moderate medical services may actually pay less in total costs despite the higher premium. Compare total annual costs across Idaho plan types →
Which Idaho Carrier Is Best for Your Situation
The best health insurance in Idaho depends on where you live, how you use healthcare, and your budget. Boise-area residents have the most options. Rural Idahoans need to prioritize network breadth. Families should compare pediatric network coverage. Self-employed residents should weigh HSA-compatible options. Below are recommendations for common Idaho situations to help narrow down the best plan.
Rural Idaho Residents
Best carrier: Blue Cross of Idaho (PPO)
The only carrier serving all 44 counties with a network covering 96% of Idaho physicians. For residents in Salmon, McCall, Grangeville, or the panhandle where carrier choices are limited, Blue Cross PPO provides the broadest access including out-of-network coverage for specialists in Boise, Pocatello, or neighboring states.
Boise Metro / Budget-Focused
Best carrier: St. Luke’s Health Plan (HMO) or Molina (HMO)
St. Luke’s offers the lowest Bronze premiums in Idaho (~$349/month for age 40), and Ada/Canyon County residents have easy access to St. Luke’s extensive hospital and clinic network. Molina offers the lowest Silver and Gold premiums. Both work well if your providers are in-network and you don’t need out-of-area coverage.
Families with Children
Best carrier: Blue Cross of Idaho or SelectHealth (PPO)
Families should prioritize pediatric specialist access. In Idaho, children’s specialty care is concentrated in the Boise and Idaho Falls areas — families in rural counties benefit from PPO flexibility. SelectHealth’s Intermountain network provides strong pediatric care in eastern Idaho near Intermountain facilities.
Self-Employed / Freelancers
Best carrier: Blue Cross of Idaho (HDHP/PPO) or PacificSource
Self-employed Idahoans can deduct health insurance premiums from taxable income. Pairing a Bronze HDHP with a Health Savings Account (HSA) maximizes tax advantages — Bronze and Catastrophic plans now qualify as HDHPs for 2026. Blue Cross of Idaho’s Bronze HDHP starts around $380/month for age 40 with access to the statewide PPO network.
Cross-Border Workers
Best carrier: Regence Blue Shield (PPO)
Regence operates across Idaho, Oregon, Washington, and Utah through the Cambia Health Solutions network. Idaho residents who commute to Ontario (OR), Pullman (WA), Logan (UT), or other border communities get seamless coverage through the Blue Cross Blue Shield national network — no out-of-network penalties for routine care in neighboring states.
Pre-Retirees (50–64)
Best carrier: Moda (POS Platinum) or Blue Cross of Idaho (PPO Gold)
Pre-retirees typically use more healthcare and value predictable costs. Moda’s Platinum POS plan (~$658/month for age 40, higher for older enrollees) covers 90% of costs with the lowest out-of-pocket exposure in Idaho. Blue Cross Gold PPO plans offer strong coverage with broader network access for residents who split time across regions.
Carrier Availability by Idaho Region
Idaho’s 44 counties have very different carrier options. The Boise metro area (Ada, Canyon, Gem) typically has six to eight carriers. Central and eastern Idaho counties see three to five carriers. The panhandle (Kootenai, Bonner, Boundary) falls in between. Blue Cross of Idaho is the only carrier available in every county statewide — making it the default option for the most rural areas.
| Region | Key Counties | Typical Carrier Count | Available Carriers |
|---|---|---|---|
| Boise Metro | Ada, Canyon, Gem | 6–8 | Blue Cross, Regence, SelectHealth, Mountain Health, Molina, Moda, PacificSource, St. Luke’s |
| Magic Valley | Twin Falls, Jerome, Cassia | 4–5 | Blue Cross, Regence, Mountain Health, Molina, St. Luke’s |
| Eastern Idaho | Bonneville, Bannock, Bingham | 3–5 | Blue Cross, Mountain Health, Molina (select counties); SelectHealth exited Bonneville for 2026 |
| Panhandle | Kootenai, Bonner, Boundary | 3–4 | Blue Cross, Regence, Mountain Health, PacificSource (select counties) |
| Central/Rural | Lemhi, Custer, Valley, Idaho | 2–3 | Blue Cross (all), Mountain Health (most); limited others |
SelectHealth’s exit from Bonneville and Franklin counties for 2026 is notable — residents of Idaho Falls, the state’s third-largest city, lost a PPO option. Blue Cross of Idaho and Regence remain the primary PPO carriers in that region. When searching for the best health insurance in Idaho, residents outside the Boise metro should start by confirming which carriers serve their county. The Idaho DOI Rate Review portal publishes carrier filings and county-by-county availability for 2026.
Idaho Health Insurance Carriers: Common Questions Answered
The most common questions about choosing the best health insurance in Idaho cover which of the 8 carriers has the lowest premiums, whether PPO is worth the extra cost in rural counties, how to keep your doctor when switching, the difference between Blue Cross of Idaho and Regence, county-by-county availability across the 44 counties, and on-exchange vs. off-exchange enrollment. Below are direct answers to the questions Idahoans ask most often before enrolling.
Which Idaho health insurance company has the lowest premiums?
St. Luke’s Health Plan offers the lowest Bronze premiums in Idaho at approximately $349/month for a 40-year-old. Molina Healthcare offers the lowest Silver premiums (~$520/month) and the lowest Gold premiums (~$548/month). However, both are HMO-only — for PPO plans, Blue Cross of Idaho Silver plans start around $481/month. Finding the best health insurance in Idaho at the lowest price requires weighing whether you need PPO provider flexibility or can work within an HMO network.
Is PPO worth the extra cost in Idaho?
For rural Idaho residents, often yes. The monthly premium difference between PPO and HMO at the Silver tier is roughly $30–50 — but PPO plans frequently have lower deductibles ($3,000 vs. $6,250 for some HMOs), which can offset the premium difference if you use moderate healthcare services. For Boise metro residents with strong in-network options, an HMO may save money without sacrificing access. For anyone who sees specialists, travels frequently, or lives in a county with limited carriers, PPO provides flexibility that’s difficult to replicate with an HMO.
Can I keep my doctor if I switch carriers?
That depends on which carrier your doctor contracts with. Before enrolling, check your preferred providers against the carrier’s provider directory. In Idaho, Blue Cross of Idaho’s CarePoint network covers 96% of physicians statewide — the broadest network. If your primary care doctor and specialists are in the St. Luke’s system, St. Luke’s Health Plan guarantees in-network access to those providers. Switching from one carrier to another during open enrollment may change which providers are in-network.
What’s the difference between Blue Cross of Idaho and Regence Blue Shield?
Both are Blue-branded carriers but they’re separate companies with different networks, plans, and pricing. Blue Cross of Idaho is Idaho-based (since 1945), serves all 44 counties, and focuses exclusively on Idaho. Regence Blue Shield of Idaho is part of Cambia Health Solutions and operates across Idaho, Oregon, Washington, and Utah. Regence administers the State of Idaho employee health plan. Both offer PPO plans with strong networks. Blue Cross has broader county coverage; Regence has stronger cross-state Blue network access.
How many carriers are available in my area?
Carrier availability varies by county. Boise metro residents typically have six to eight carriers. Eastern Idaho and the panhandle see three to five. Rural central Idaho counties may have only two or three — with Blue Cross of Idaho being the only carrier guaranteed in all 44 counties. Enter your zip code at yourhealthidaho.org to see exactly which carriers and plans are available where you live.
Does it matter if I buy a plan on the exchange or directly from a carrier?
If you qualify for a premium tax credit (household income between 100% and 400% FPL using 2025 FPL for 2026 marketplace), you must enroll through Your Health Idaho to receive the subsidy. If you earn above 400% FPL ($62,600 for an individual), on-exchange and off-exchange plans from the same carrier cost the same. Off-exchange enrollment can make sense for higher-income residents who want PPO plans and don’t need subsidies — the same Blue Cross of Idaho or Regence PPO is available either way.
