PPO vs HMO in 2027: What’s the Difference?
An HMO usually covers only in-network care and often requires a referral before you see a specialist. A PPO lets you use out-of-network providers without a referral, for an additional cost. Here’s how networks, referrals, out-of-network rules, premiums and cost sharing compare for 2027 — plus where EPO and POS plans fit.
Get My Free Quote ↓Quick answer: The main difference is network flexibility versus cost. An HMO generally covers only in-network care (except emergencies) and often requires a primary care doctor’s referral to see a specialist, usually in exchange for a lower premium. A PPO lets you use out-of-network providers without a referral, at a higher cost. On the ACA Marketplace, both types must cap 2027 in-network out-of-pocket costs at no more than $12,000 for one person ($24,000 for a family).

PPO vs HMO: What You Need to Know
PPO vs HMO is mostly a choice about networks. An HMO (health maintenance organization) is, in HealthCare.gov’s words, a plan that “usually limits coverage to care from doctors who work for or contract with the HMO.” A PPO (preferred provider organization) charges you less when you use its network but lets you use providers outside it “without a referral for an additional cost.” For the ground-up explainers, see what HMO insurance is and what PPO insurance is.
Plan type and metal level are separate choices. A Bronze, Silver, Gold or Platinum Marketplace plan can be an HMO, a PPO, or one of the in-between types: an EPO or a POS plan. So compare the plan type and the total cost, not the label alone.

Straight talk: A plan sold outside the Marketplace can cost less than a full-price ACA plan if you’re healthy, earn too much for a tax credit, or want a specific network. But if you qualify for a tax credit or Medicaid, have a pre-existing condition, are pregnant or planning to be, or take expensive medications, an ACA plan is usually the safer buy, and the only way to get the premium tax credit is through the Marketplace. We’ll price both side by side before you decide. Call (844) 788-3733.
PPO vs HMO Comparison Table for 2027
These are the HMO vs PPO differences that matter most when you choose. Every plan sets its own rules, so confirm each row in the plan’s Summary of Benefits and Coverage (SBC) before you enroll.
| Feature | HMO | PPO |
|---|---|---|
| Network rule | In-network care only, except emergencies | In-network care, plus out-of-network care at a higher cost if the plan includes it |
| Primary care doctor | Often required; you pick one from the network | Usually not required |
| Specialist referral | Often required | Not required |
| Non-emergency out-of-network care | Generally not covered; you pay the full bill | Usually covered at a higher cost share, often after a separate deductible; balance billing possible |
| Emergency care | Covered, even out of network | Covered, even out of network |
| Where you live | May require you to live or work in its service area | Network reach varies by plan; check the directory |
| Monthly premium | Often, not always, lower | Often higher; you pay for the out-of-network option |
| Cost sharing | Often flat copays for office visits | Copays or coinsurance in network; higher costs out of network |
| 2027 Marketplace out-of-pocket limit | No more than $12,000 / $24,000 for in-network care | No more than $12,000 / $24,000 for in-network care; out-of-network costs don’t count toward it |
| Paperwork | Referrals go through your primary care doctor | You may have to file your own out-of-network claims |
| Usually fits | Your doctors are in one local network and you want the lower premium | You need a specific out-of-network doctor, see specialists often, or split time between states |
Out-of-pocket limits are the 2027 ACA maximums for one person / a family (CMS). Emergency coverage reflects the federal No Surprises Act protections, which apply to group health plans and individual health insurance coverage (45 CFR 149.110).
Short version: if every doctor you use is in an HMO’s network, the HMO often gives you the same in-network care for a lower premium. Pay for a PPO when out-of-network access is worth real money to you.
How HMO Networks and Referrals Work
An HMO contracts with a set group of doctors, hospitals and other providers and generally pays only when you use them. HealthCare.gov notes that an HMO generally won’t cover out-of-network care except in an emergency, may require you to live or work in its service area to be eligible, and often focuses on integrated care, prevention and wellness.
The primary care doctor and the referral
Many HMOs ask you to choose a primary care physician (PCP) from the network when you enroll. Your PCP is your first stop for non-emergency care and sends you to an in-network specialist when you need one. A typical referral works like this:
1. You have a problem that needs a specialist, such as persistent knee pain. 2. You see your in-network PCP first. 3. Your PCP agrees you need an orthopedist and sends a referral through the plan. 4. You see an in-network specialist, and the visit is covered under your plan’s cost sharing. Some services, such as imaging or surgery, may also need prior authorization on top of the referral.
If you skip a required referral and book the specialist directly, the plan can deny the claim, even when the specialist is in the network. That is the HMO trade: fewer choices and more steps, usually in exchange for a lower premium.
Referral exceptions you’re entitled to
Under federal rules (45 CFR 149.310), if a plan has you designate a primary care provider, it generally must let you choose any participating PCP who is available to accept you, and let you choose an in-network pediatrician as a child’s PCP. The plan also can’t require a referral for obstetrical or gynecological care from an in-network OB/GYN. Emergency care needs no referral or prior authorization, even out of network (45 CFR 149.110). Some HMOs also allow direct access to other services, such as routine eye exams or behavioral health; check the plan’s SBC and plan documents for which ones.
How PPO Out-of-Network Coverage Works
A PPO contracts with a network of “preferred” providers at negotiated rates. You don’t need a PCP or a referral, so you can book in-network specialists directly. You pay the least in the network, and you can use providers outside it for an additional cost.
That additional cost is often bigger than people expect. Out of network, a PPO typically pays a smaller share of the bill, often after a separate, higher deductible, and the provider can bill you the difference between their charge and what the plan pays (balance billing). HealthCare.gov notes that the out-of-pocket limit doesn’t include out-of-network care or costs above the allowed amount, so those bills can keep growing after you reach your in-network limit. Some PPOs set a separate, higher out-of-network limit. Our PPO out-of-network coverage guide walks through the math.
A “PPO” label doesn’t guarantee out-of-network coverage
Some plans that use a PPO network cover in-network care only, except emergencies. Read the out-of-network column before you buy. PPO plans with out-of-network benefits typically charge more out of network. In the non-Marketplace PPO plans we reviewed, that meant 50% coinsurance after a separate, higher deductible.
Out-of-network costs in the non-Marketplace PPO designs we reviewed that include out-of-network benefits: Out-of-network providers may bill you for the difference between their charge and what the plan pays. That amount doesn’t count toward your out-of-pocket limit. Out-of-network preventive care and prescriptions are not covered.
Care in another state
An HMO or EPO generally covers only emergencies outside its network or service area, so routine care while you travel, or for a child at an out-of-state college, may not be covered. A PPO with out-of-network benefits generally also pays for covered care from out-of-network providers, at its higher out-of-network cost share, and some PPO networks reach farther than a local HMO’s. Network reach varies by plan, so check the directory for every area where you need care.
Is an HMO Cheaper Than a PPO in 2027?
On the monthly premium, often yes, but not always, and the premium is only part of the cost. Premiums depend on the insurer, network, plan design, metal level and where you live. Your total cost for the year is the premiums plus what you pay when you get care: deductibles, copays and coinsurance. A low-premium HMO with a high deductible can cost more than a PPO if you need a lot of care, and a PPO’s out-of-network option is worth nothing if you never use it.
How the tax credit changes the PPO vs HMO math
On the Marketplace, the premium tax credit is generally the premium of the benchmark plan (the second-lowest-cost Silver plan) minus a set percentage of your household income, and it can’t be more than the premium of the plan you pick (IRS). The credit is the same dollar amount whichever plan type you choose. So if you pick a PPO that costs more than an HMO, you pay the whole difference yourself.
Worked example (2027 rules, one person, $48,000 income): Marketplace savings for 2027 use the 2026 poverty guideline of $15,960 for one person (48 states and DC), so $48,000 is about 301% of the federal poverty level (FPL). At 300%–400% FPL, the 2027 expected contribution is 10.22% of income (IRS Rev. Proc. 2026-26): $48,000 × 10.22% = $4,905.60 a year, or $408.80 a month for the benchmark Silver plan. Your tax credit is the benchmark premium minus $408.80 (no credit if the benchmark costs less than that). An HMO priced below the benchmark costs you less than $408.80 a month; a PPO priced above it costs you $408.80 plus every dollar of the difference. Run your own numbers with our 2027 ACA subsidy calculator.
Over 400% FPL (about $63,840 for one person or $132,000 for a family of four for 2027 coverage), there is no tax credit under current law, because the enhanced credits expired after 2025. You pay the full premium for either plan type, which is when it can be worth also pricing a PPO sold outside the Marketplace (see below).
At or below 250% FPL (about $39,900 for one person), look at Silver plans first, HMO or PPO. Cost-sharing reductions come only with Silver plans bought through the Marketplace and cut the 2027 in-network out-of-pocket limit for one person to $4,000 at 100%–200% FPL and $9,600 at 200%–250% FPL, versus $12,000 on a standard plan (CMS).

Where EPO and POS Plans Fit
HMO and PPO aren’t the only choices. Two other plan types mix their rules.
EPO (exclusive provider organization)
HealthCare.gov describes an EPO as a plan where services are covered only if you use doctors, specialists or hospitals in the plan’s network, except in an emergency. Like an HMO, it doesn’t pay for non-emergency out-of-network care; unlike many HMOs, many EPOs don’t require a referral to see an in-network specialist. EPO premiums are often, not always, below a comparable PPO. Compare the two in our EPO vs PPO guide.
POS (point of service)
A POS plan charges you less when you use its network and, per HealthCare.gov, requires a referral from your primary care doctor to see a specialist, like an HMO. Many POS plans also pay for some out-of-network care at a higher cost, like a PPO. See our point-of-service plan guide.
Which plan types can you buy?
It depends on your county and the insurers that sell there, and every plan’s Summary of Benefits and Coverage names its plan type. In many areas we see more HMO and EPO choices than PPOs on the Marketplace; that’s our observation from quoting, not a national statistic. If you can’t find a PPO, we can show you every plan type sold in your ZIP code.
HMO or PPO: Which Is Better for You?
Neither is better for everyone. Start with your doctor list, then your budget, then how often you need care away from home.
Choose an HMO if…
Your doctors and hospital are in the HMO’s network, you rarely see specialists or don’t mind referrals, you stay in one area, and you want a lower premium. If you qualify for cost-sharing reductions, compare Silver HMOs first.
Choose a PPO if…
You have a must-keep doctor outside the HMO networks, see several specialists and want to book them directly, split time between states, or need a specific hospital or academic medical center, and the out-of-network option is worth the higher premium.
Consider an EPO if…
You want to see in-network specialists without referrals but don’t need out-of-network coverage, and the local network is broad enough for you.
Consider a POS plan if…
You’re fine with a primary care doctor coordinating your care but want some out-of-network coverage for one specific doctor or service.
Check your doctors before you choose
List your doctors, specialists, hospital and prescriptions, then check each one in the plan’s provider directory and drug list, or call the insurer. If a doctor you can’t replace isn’t in an HMO’s network, either change doctors and keep the lower premium, or pick a PPO or EPO that includes them.

Switching plan types for 2027
You can usually move from an HMO to a PPO (or back) only during Open Enrollment or a Special Enrollment Period. Open Enrollment for 2027 coverage on HealthCare.gov runs November 1, 2026 to January 15, 2027; enroll by December 15 for coverage that starts January 1. State-based marketplaces can set different dates. Outside that window you need a qualifying life event, such as losing other coverage, moving, marriage or a new baby, which usually gives you 60 days to pick a plan. See Special Enrollment Periods.
The regrets we hear most: choosing an HMO and then needing several specialists; moving to an area where the HMO’s network is thin; paying for a PPO but only ever using in-network doctors; and buying a PPO whose out-of-network deductible is so high the benefit rarely pays.
PPO Plans Sold Outside the Marketplace
If you earn too much for a tax credit and want a PPO network, you may also see PPO and EPO plans sold outside the ACA Marketplace. Some private plans rent access to the Cigna PPO network. Your plan administrator, not Cigna, may process your claims. Check your ID card and search Cigna’s directory for the network named on it. Some private PPO plans we offer are group health plans offered through a sponsoring employer or organization, not individual ACA plans. You can apply for these plans outside Open Enrollment, but approval depends on each plan’s eligibility rules and may involve underwriting, and the start date depends on the plan. Learn more about private health insurance.
Network notice: The Cigna PPO network is a provider network, not an insurance company, and it doesn’t pay claims. A plan that uses the Cigna PPO network sets its own benefits and pays claims through its own administrator. Before you get care, confirm your doctor or facility is in network using the directory and phone number on your plan ID card.
Not a Marketplace plan: These plans are not sold through the ACA Health Insurance Marketplace (HealthCare.gov or your state’s exchange) and are not individual-market ACA plans. You can’t use a premium tax credit or cost-sharing reduction to pay for them. As HealthCare.gov puts it, “the only way to get the premium tax credit is through the Marketplace.”
Group plan notice (the group PPO designs described above): This is a group health plan offered through a sponsoring employer or organization, not an individual ACA plan. Its Summary of Benefits and Coverage states that it provides minimum essential coverage and meets the minimum value standard. If you are eligible for certain types of minimum essential coverage, you may not be eligible for the premium tax credit. Eligibility is set by the plan document.
Pre-certification: Some services, such as imaging, surgery and hospital stays, need pre-certification before you get them. If you skip it, the plan may charge a penalty ($500 in the plans we reviewed), and in most of those plans the penalty doesn’t count toward your out-of-pocket limit.
When a private PPO can make sense
The case is strongest when most of these are true: your income is above 400% FPL (about $63,840 for one person or $132,000 for a family of four for 2027 coverage, as of fall 2026 under current law), so you’d pay full price for an ACA plan; you’re healthy, with low, predictable use and generic drugs only; you want the Cigna PPO network with an out-of-network option, or a specific doctor in that network; you accept a higher stated deductible (about $5,000–$9,000 for one person, in network, in the plans we reviewed); and you qualify through the plan’s sponsoring group, which we confirm.
When an ACA plan is the better call
Choose the Marketplace if you qualify for a tax credit or Medicaid, have a pre-existing condition or ongoing treatment, are pregnant or planning to be, take expensive brand or specialty drugs, or want a firm out-of-pocket ceiling ($12,000 for one person in 2027). All Marketplace plans must cover treatment for pre-existing medical conditions. For any private plan, ask us to confirm in writing how it handles pre-existing conditions before you enroll.
