HMO vs PPO: Key Differences and How to Choose

Key takeaways

• An HMO (Health Maintenance Organization) costs less but limits you to in-network providers and requires referrals to see specialists

• A PPO (Preferred Provider Organization) offers more flexibility to see any provider — including out-of-network — but comes with higher premiums

• Your best choice depends on how often you use healthcare, whether you want to keep specific doctors, and how much you're willing to spend on premiums versus out-of-pocket costs

• For employers managing hourly teams, the right health plan can directly affect recruitment, retention — 68.4% of workers cite health insurance as a key driver — and employee satisfaction

Whether you're choosing health insurance for yourself or selecting a plan to offer your employees, understanding the difference between an HMO and a PPO is essential. These two plan types work differently when it comes to costs, provider access, and how much freedom you have to see specialists. The right choice depends on your healthcare needs, budget, and how much flexibility matters to you.

If you're a business owner weighing up health plans for your team, providing health insurance is optional if your business has fewer than 50 full-time employees. However, you may choose to offer this perk to attract and retain the best employees. Let's break down what you need to know.

HMO vs PPO at a glance

If you're short on time, here's a quick side-by-side comparison of the two most common health plan types:

How an HMO works

A Health Maintenance Organization (HMO) is a prepaid health plan that gives you access to a network of doctors, specialists, and hospitals. When you enroll in an HMO, you choose a primary care physician (PCP) who becomes your main point of contact for all healthcare needs.

Your PCP acts as a gatekeeper. If you need to see a specialist — say, a cardiologist or orthopedic surgeon — your PCP must provide a referral first. Without that referral, your insurance won't cover the visit. The exception is emergency care, which is covered at any hospital, even if it's outside your HMO network. Women can also see a gynecologist or obstetrician for routine care without a referral.

HMOs emphasize preventive care like immunizations, annual physicals, and screenings. The idea is to catch health issues early before they become serious — and expensive. When you visit a doctor or hospital, you'll typically pay a small copayment rather than dealing with complex billing. You show your card, and that's it.

Pros of an HMO

• Lower premiums and annual deductibles compared to PPOs

• Predictable costs with simple copays for most visits

• Less paperwork — no claim forms to fill out at the time of care

• Strong focus on preventive care, which can help you stay healthier long-term

• Emergency care is covered at any hospital, even out of network

Cons of an HMO

• You must stay in-network for all non-emergency care

• You need a referral from your PCP to see any specialist

• If you disagree with your PCP's decision not to refer you, you have limited options

• Network size varies by state, which may limit your choices

• You may experience longer wait times for appointments compared to other plan types

How a PPO works

A Preferred Provider Organization (PPO) is a prepaid health plan that offers a network of preferred doctors and hospitals — but with a key difference from an HMO. You don't need a primary care physician, and you don't need referrals to see specialists. You can book an appointment with a dermatologist, physical therapist, or any other specialist directly.

PPOs also let you see providers out-of-network. If you have a doctor you love who isn't in the PPO network, you can still see them — you'll just pay more out of pocket. Most of your costs are covered when you use preferred providers, but you have the flexibility to go outside the network when it matters to you.

Like HMOs, PPO members show a card when accessing care rather than filling out claim forms. The provider network is typically larger than an HMO's, giving you more options for doctors and facilities.

Pros of a PPO

• No referrals needed — see any specialist directly

• Freedom to see any doctor, whether in-network or out-of-network

• Larger provider networks give you more choices

• Great for people who travel frequently or have multiple specialists

• You can keep seeing your existing doctors even if they're out of network

Cons of a PPO

• Higher premiums and annual deductibles than HMOs

• Out-of-network care can get expensive quickly, with no federal limit on out-of-network costs

• More complex billing, especially when using out-of-network providers

• You're responsible for a larger share of costs overall

Key differences between HMO and PPO plans

Now that you understand how each plan works, let's dig deeper into the differences that matter most when making your decision.

Cost comparison

With employer health benefit costs projected to rise 6.7% in 2026, the most obvious difference between HMO and PPO plans is cost. HMOs have lower premiums — the amount you pay each month — and lower deductibles. In exchange, you accept more restrictions on which providers you can see.

PPOs cost more upfront, but you're paying for flexibility. According to the Kaiser Family Foundation's (KFF) 2025 Employer Health Benefits Survey, the average annual premium for employer-sponsored family coverage is $26,993, with workers contributing an average of $6,850 toward that cost. PPO plans typically sit at the higher end of these averages.

If you rarely use healthcare, an HMO's lower premiums might save you money. But if you need frequent specialist visits or prefer out-of-network doctors, a PPO's higher premiums could be worth the trade-off.

Provider networks and referrals

This is where the day-to-day experience of each plan differs most. With an HMO, your primary care physician controls access to specialists. If you think you need to see a dermatologist, you first visit your PCP, explain your symptoms, and wait for a referral. Some people find this frustrating — especially if they already know what kind of care they need.

With a PPO, you skip that step entirely. You can book directly with any specialist, in-network or out. The trade-off is cost: staying in-network keeps your expenses lower, while going out-of-network means higher copays, separate deductibles, or coinsurance.

PPO networks are generally larger than HMO networks, so you're more likely to find your preferred doctors included. But network size varies by city and state, so it's worth checking the provider directory before you enroll.

How to choose between an HMO and a PPO

There's no universally "better" plan — the right choice depends on your situation. Here are the questions to ask yourself during open enrollment:

1. How often do you visit the doctor? If you're generally healthy and only need annual checkups, an HMO's lower costs make sense.

2. Do you see multiple specialists? If you regularly visit a cardiologist, dermatologist, and physical therapist, a PPO's no-referral policy saves time and hassle.

3. Do you have doctors you want to keep? Check whether they're in-network. If they're not, a PPO lets you keep seeing them — at a higher cost.

4. Do you travel frequently? PPOs offer more flexibility for getting care in different cities or states.

5. What's your budget priority — lower monthly costs or lower out-of-pocket risk? HMOs win on premiums; PPOs offer more predictable access to care.

When an HMO makes more sense

An HMO is often the better fit if you're budget-conscious, generally healthy, and comfortable with one primary care doctor managing your care. You'll pay less each month, and the simpler structure works well if you don't need frequent specialist visits. If you don't travel much and your preferred doctors are in-network, an HMO keeps things straightforward.

When a PPO makes more sense

A PPO makes sense if you value flexibility above all else. You want to see specialists without jumping through hoops, you have existing doctors you don't want to leave, or you travel often and need care in multiple locations. You're willing to pay higher premiums for the freedom to make your own healthcare decisions without a gatekeeper.

Why health benefits matter for shift-based teams

If you're an employer managing hourly workers, the health plan you offer isn't just a line item — it's a retention tool. According to Deputy's Big Shift Report 2025, 15% of healthcare employees are considering leaving their current jobs to move to another company, another industry, or leave the workforce entirely. Competitive benefits can be the difference between keeping your best people and losing them.

The data backs this up. Over 60% of US shift workers say their employers have offered additional benefits such as free mental health programs, financial education, same-day pay, free meals, or cashback offers, according to Deputy's research on employee retention strategies. Health insurance sits at the top of that benefits hierarchy.

For employers, choosing between an HMO and a PPO isn't just about cost — it's about what your team values. Younger, healthier workers might prefer lower premiums. Employees with families or chronic conditions might prioritize flexibility. Some employers offer both options so employees can self-select.

And with 18% of US shift workers holding multiple jobs, predictable healthcare costs matter even more. Workers juggling multiple employers need to know what they're paying and what they're getting.

Other health plan types to know

HMOs and PPOs are the most common plan types, but they're not your only options. Here's a quick overview of other plans you might encounter.

Point-of-Service (POS) plans

A POS plan is a hybrid between an HMO and a PPO. Like an HMO, you choose a primary care physician who coordinates your care. But like a PPO, you can go out-of-network — you'll just pay more. If your PCP refers you to an out-of-network specialist, the plan covers most or all of the cost. If you refer yourself, you'll pay coinsurance.

POS plans work well if you want the cost savings of an HMO but need occasional flexibility to see out-of-network providers.

Exclusive Provider Organization (EPO) plans

An EPO is similar to an HMO in that you must stay in-network for coverage — there's no out-of-network benefit except for emergencies. But unlike an HMO, you typically don't need a primary care physician or referrals to see specialists. Think of it as an HMO with fewer hoops to jump through, but the same network restrictions.

High Deductible Health Plans (HDHPs) and HSAs

A High Deductible Health Plan (HDHP) has lower premiums but higher deductibles — you pay more out of pocket before insurance kicks in. According to the Internal Revenue Service (IRS), a plan qualifies as an HDHP in 2024 if the deductible is at least $1,600 for an individual or $3,200 for a family.

HDHPs are often paired with a Health Savings Account (HSA), a tax-advantaged savings account for medical expenses. In 2024, you can contribute up to $4,150 as an individual or $8,300 for a family, according to IRS Publication 969. The money rolls over year to year and stays with you if you change jobs.

HDHPs work well for healthy people who want lower premiums and are comfortable setting aside money for potential medical expenses. They're less ideal if you have ongoing health needs that would quickly eat through your deductible.

Flexible Spending Accounts (FSAs) are another option for saving pre-tax dollars for healthcare expenses, but unlike HSAs, the money typically doesn't roll over — use it or lose it.

Frequently asked questions

Which is better for someone who rarely sees a doctor — an HMO or a PPO?

An HMO is usually the better fit if you rarely see a doctor, because you'll pay lower premiums and minimal copays for the occasional visit. Since you won't need frequent specialist access, the referral requirement won't be a burden. You'll save money each month and still have coverage when you need it.

Can you see a specialist without a referral on an HMO plan?

No — most HMO plans require a referral from your primary care physician before you can see a specialist, except for emergency care and certain women's health services like obstetrician/gynecologist (OB/GYN) visits. Your PCP acts as a gatekeeper who decides whether specialist care is necessary.

What happens if you go out of network with a PPO?

You can still receive care, but you'll pay a larger share of the cost — typically through higher copays, a separate out-of-network deductible, or coinsurance. The exact amount depends on your specific plan, so check your benefits summary before scheduling an out-of-network appointment.

Can employers offer both HMO and PPO options to their team?

Yes — many employers offer both plan types so employees can choose the one that fits their needs and budget. This is especially useful for diverse hourly workforces where some employees prioritize low costs while others value flexibility. Offering choice can improve satisfaction and retention.

What's the difference between an HMO and an EPO?

An EPO also limits you to in-network providers, but unlike an HMO, you typically don't need a primary care physician or referrals to see specialists. Both plan types exclude out-of-network coverage except for emergencies. EPOs offer more flexibility within the network while keeping costs lower than a PPO.
