Which type of health insurance plan is right for you?
Published May 30, 2026
Health insurance plans differ mainly in how they handle networks, referrals, and out-of-network care. The main types — HMO, PPO, EPO, POS, and high-deductible plans — trade flexibility against cost in different ways. Knowing how each works helps you weigh premiums against the freedom to choose providers.
HMO
A Health Maintenance Organization usually asks you to pick a primary care doctor and get referrals for specialists, with coverage limited to in-network providers except in emergencies. Premiums are typically lower.
PPO
A Preferred Provider Organization lets you see specialists without a referral and covers some out-of-network care at a higher cost. It offers the most flexibility, usually at a higher premium.
EPO
An Exclusive Provider Organization covers only in-network providers, like an HMO, but usually does not require referrals.
POS
A Point of Service plan blends HMO and PPO features: you choose a primary care doctor and need referrals, but you get limited out-of-network coverage.
High-deductible plans and HSAs
A high-deductible health plan has lower premiums and a higher deductible, and it can pair with a tax-advantaged health savings account (HSA) for qualified expenses.
Catastrophic and short-term plans
Catastrophic plans cover worst-case costs for eligible younger or hardship enrollees. Short-term plans fill gaps but often exclude pre-existing conditions and essential benefits. Medicare and Medicaid are separate public programs with their own rules.
Frequently asked questions
＋ What is the difference between an HMO and a PPO?
An HMO limits you to in-network providers and usually requires referrals, with lower premiums. A PPO lets you see specialists without referrals and covers some out-of-network care at a higher cost.
＋ What does HDHP mean?
A high-deductible health plan has a lower premium and a higher deductible. If it qualifies, you can pair it with a health savings account to pay for medical expenses with pre-tax dollars.
＋ Can I buy health insurance outside of open enrollment?
Usually only if you qualify for a special enrollment period after a life event such as marriage, a new baby, or losing other coverage. Medicaid enrollment is open year-round for those who qualify.
＋ Are short-term health plans a good substitute?
Short-term plans can fill a temporary gap but often exclude pre-existing conditions and may not cover essential benefits, so read the terms before relying on one.
