🚀 Fast Facts: HMO vs. PPO
- An HMO usually has lower premiums but covers only in-network care, except emergencies
- A PPO usually costs more but covers some out-of-network care and doesn't require referrals
- 46% of workers with employer coverage are in a PPO and 12% are in an HMO (KFF, 2025)
- Either plan type can be HSA-qualified if it meets the IRS high-deductible rules
HMO vs PPO, in short: an HMO (health maintenance organization) plan usually costs less each month but asks you to stay in the plan's network and get referrals from a primary care physician. A PPO (preferred provider organization) plan usually costs more but lets you see specialists without referrals and gives you some out of network coverage. The right health plan depends on your budget, your doctors, and how much flexibility you need.
What is an HMO plan?
HMO stands for health maintenance organization. An HMO is a health insurance plan that covers care from a defined network of doctors, hospitals, and other health care providers that contract with the insurance company. According to HealthCare.gov, an HMO generally won't cover out of network care except in an emergency.
Most HMO plans ask you to choose a primary care physician (PCP). Your primary care provider handles routine care and gives you a referral when you need specialty care, which keeps your care coordinated in one place. Some services, such as OB-GYN visits, often don't need a referral, but rules vary by plan. For a fuller explanation, see our guide to what an HMO is and how it works.
What is a PPO plan?
PPO stands for preferred provider organization. A PPO is a health insurance plan that charges you less when you use providers in the plan's network, but still pays part of the cost when you see an out of network provider. HealthCare.gov notes that you can also use providers outside the network for an additional cost.
With a PPO, you usually don't need to choose a primary care physician, and you can visit specialists without a referral. That flexibility is why the PPO is the most common plan type for workers with employer coverage: KFF's 2025 Employer Health Benefits Survey found 46% of covered workers are in a PPO, compared with 12% in an HMO.
HMO vs PPO: key differences at a glance
Feature | HMO plan | PPO plan |
Monthly premiums | Usually lower | Usually higher |
Primary care physician | Usually required | Usually not required |

Plans differ, so always check the plan's Summary of Benefits and Coverage before you enroll.
How HMO and PPO costs compare
When comparing plans, look at total cost, not just monthly premiums. What you pay in a year is your premiums plus out of pocket costs: your deductible, copays, and coinsurance.
Premiums. HMO plans usually have lower monthly premiums than PPO plans. In KFF's 2025 survey, the average annual premium for single coverage in a PPO was $9,818, above the $9,325 average across all plan types. These totals include what employers pay, so your share from each paycheck is smaller.
Deductibles. HMO plans are much more likely to skip the deductible. KFF found that 47% of covered workers in HMOs have no general annual deductible for single coverage, compared with 12% of workers in PPOs. To see how a deductible works, read what is a deductible.
Copays and coinsurance. HMO plans tend to use fixed copays for visits. PPO plans more often use coinsurance, where you pay a percentage of the bill after your deductible, and the percentage is higher out of network.
Out of network costs. In an HMO, you usually pay the full cost of non-emergency out of network care. In a PPO, out of network care is covered at a higher cost, and an out of network doctor may also bill you for the difference between their charge and what the plan allows, called balance billing. Federal rules protect you from most surprise bills for emergency care.
Out-of-pocket maximum. Both plan types cap what you pay for covered in-network care in a year. For 2026, the federal limit for most plans is $10,600 for an individual and $21,200 for a family. Learn more in deductible vs. out-of-pocket maximum.
Network, referrals, and specialists
For many people, the bigger question is which doctors they can see. With an HMO, the HMO network is usually local or regional. If you live and get care in one area, that works well. If you travel often or have a child in college out of state, routine care outside the network generally isn't covered, though emergency care is.
A PPO gives you more flexibility. You can visit specialists directly and see out of network doctors at a higher cost, which helps if you already have doctors you want to keep or need care in more than one state. The trade-off is more work: before an appointment, you check whether a provider is in network, and you may need to file claims yourself for out of network services.
Before you choose, look up your current doctors, hospitals, and pharmacy in each plan's provider directory. A plan with lower premiums isn't a good deal if your doctors aren't in its network.
HMO and PPO plans with an HSA or FSA
An HSA isn't tied to whether a plan is an HMO or a PPO. To contribute to an HSA, you need HSA-qualified coverage, usually a high-deductible health plan (HDHP). For 2026, an HDHP must have a deductible of at least $1,700 for self-only coverage or $3,400 for family coverage, and the HSA contribution limit is $4,400 or $8,750 (IRS Rev. Proc. 2025-19). An HDHP can use an HMO or PPO network, so check whether a plan is labeled "HSA-qualified." Starting in 2026, bronze and catastrophic plans also count as HSA-compatible; see our guide to the 2026 HSA eligibility expansion.
A health FSA works with any plan type your employer offers, including an HMO or PPO. The 2026 health FSA limit is $3,400. Both accounts can pay deductibles, copays, and coinsurance with pre-tax money. For a side-by-side look, see HSA vs FSA, and for how an HDHP compares with a PPO, see PPO vs HDHP.
Other plan types: EPO and POS
HMO and PPO aren't your only options. An EPO plan (exclusive provider organization) covers only in network care except in emergencies, like an HMO, but usually doesn't require referrals, like a PPO. See EPO vs PPO for a closer comparison.
A POS plan (point of service) is a hybrid. POS stands for point of service: you choose a primary care physician and need referrals, like an HMO, but you get some out of network benefits, like a PPO. HealthCare.gov has a short summary of each plan type.
How to choose between an HMO and a PPO
There's no single best health plan. Here's who each plan type tends to fit.
An HMO may fit if you:
- Get most of your medical care in one area
- Want lower monthly premiums and predictable copays
- Like having a primary care physician coordinate your care
- Don't need to keep a specific out of network doctor
A PPO may fit if you:
- Want to visit specialists without referrals
- Have doctors or hospitals you want to keep that aren't in an HMO network
- Travel often or get care in more than one state
- Are willing to pay higher premiums for more flexibility
You can usually change plans only during open enrollment or after a qualifying life event, such as marriage, a new baby, or losing other coverage, which opens a special enrollment period. For the other terms you'll see on plan documents, use our open enrollment cheat sheet.
