Compare PPO, HMO, EPO, and POS health insurance plans. Learn the differences in networks, costs, referrals, and flexibility to choose the right plan for you.
Understanding Health Insurance Plan Types
PPO, HMO, EPO, and POS are different types of health insurance plans that vary in how you access care, whether you need referrals, and what happens if you see out-of-network providers. Understanding these differences helps you choose a plan that matches your healthcare needs and preferences.
HMO (Health Maintenance Organization)
HMOs are the most restrictive but often most affordable plan type. You choose a primary care physician (PCP) who coordinates all your care and provides referrals to specialists.
- Must choose a primary care physician (PCP)
- Need referrals from PCP to see specialists
- No out-of-network coverage except emergencies
- Must use network providers for coverage
- Lower premiums than PPOs
- Lower out-of-pocket costs when using network
- Good for people who don't mind coordinated care
- Best for those who want lower costs and simpler decisions
PPO (Preferred Provider Organization)
PPOs offer the most flexibility. You can see any provider—in or out of network—without referrals, but you'll pay less using in-network providers.
- No PCP required (but can choose one)
- No referrals needed to see specialists
- Out-of-network coverage available (at higher cost)

- Higher premiums than HMOs
- More flexibility = higher costs

EPO (Exclusive Provider Organization)
EPOs are a hybrid between HMOs and PPOs. Like PPOs, you don't need referrals. Like HMOs, you have no out-of-network coverage (except emergencies).

POS plans combine elements of HMOs and PPOs. You have a PCP and need referrals like an HMO, but you can go out-of-network like a PPO (at higher cost).
- Must choose a primary care physician

- Out-of-network coverage available (at higher cost)
- In-network care works like an HMO

Frequently Asked Questions
What is the difference between PPO and HMO?
PPOs offer more flexibility—you can see any provider without referrals, including out-of-network doctors. HMOs require you to choose a primary care physician, get referrals for specialists, and stay in-network. PPOs cost more but offer more freedom.
Is PPO or HMO better?
It depends on your priorities. Choose an HMO if you want lower costs and don't mind having a PCP coordinate your care. Choose a PPO if you want flexibility to see any doctor without referrals, even if it costs more.
What is an EPO plan?
An EPO (Exclusive Provider Organization) combines features of HMOs and PPOs. Like a PPO, you don't need referrals to see specialists. Like an HMO, you must stay in-network for coverage (except emergencies). Premiums are typically in between.
Do I need a referral to see a specialist with a PPO?
No. PPO plans do not require referrals. You can see any specialist directly, whether in-network or out-of-network. This is one of the main advantages of PPO plans.
What happens if I go out-of-network with an HMO?
With an HMO, out-of-network care is generally not covered except for emergencies. You would pay the full cost yourself. This is why it's important to verify providers are in-network before receiving care with an HMO.
Which plan type has the lowest premiums?
HMO plans typically have the lowest premiums because they have the most restrictions on care. EPO and POS plans are usually in the middle. PPO plans typically have the highest premiums due to their flexibility.
