The main difference between PPO and POS health insurance is how you access care. A PPO generally gives you more freedom to see specialists without referrals and to use out-of-network providers at a higher cost. A POS plan generally relies more heavily on primary-care coordination and requires referrals to specialists. Actual premiums, deductibles, provider networks, out-of-network benefits, and other cost-sharing vary by plan.
Key Takeaways
- PPO plans emphasize flexibility. You generally pay less in-network but can use out-of-network providers for additional cost and typically do not need a primary-care referral to see a specialist.
- POS plans emphasize primary-care coordination. HealthCare.gov defines POS plans as requiring a referral from your primary care doctor to see a specialist.
- Out-of-network care can be expensive. PPOs generally provide an out-of-network option, while POS plans commonly may provide one depending on the plan’s terms, usually with greater cost-sharing.
- Neither plan type is automatically cheaper. Premiums, deductibles, copays, coinsurance, networks, and out-of-pocket exposure must be compared using the actual plans.
- A referral is not the same as prior authorization. Either type of plan may require prior authorization for certain services or prescriptions even when no specialist referral is required.
What Is a PPO Health Insurance Plan?
PPO stands for Preferred Provider Organization. A PPO contracts with doctors, hospitals, and other health care providers to form a network. HealthCare.gov explains that members generally pay less when they use providers within that network.
One of the defining advantages of a PPO is flexibility. A PPO generally allows you to obtain covered care from providers outside the network, although your share of the cost can be higher. Depending on the plan and circumstances, out-of-network care can also expose you to charges that would not apply when using contracted providers.
PPO members also generally have greater freedom to see specialists without first obtaining a referral from a primary care provider. That can be useful for someone who regularly uses specialists or does not want a primary care physician to act as the main gateway to specialty care.
PPO flexibility does not mean every service is automatically covered. A PPO can still use deductibles, copays, coinsurance, prior authorization, medical-necessity rules, prescription formularies, exclusions, and other plan requirements.
What Is a POS Health Insurance Plan?
POS stands for Point of Service. HealthCare.gov describes a POS plan as one in which you pay less when you use doctors, hospitals, and other providers that belong to the plan’s network. It also states that POS plans require a referral from your primary care doctor to see a specialist.
POS designs commonly combine features associated with more tightly managed plans and PPO-style out-of-network options. State insurance-regulator guidance describes POS coverage as commonly allowing members to obtain some care outside the network while requiring them to pay more. Exact out-of-network benefits and referral procedures depend on the specific plan.
The primary care relationship is therefore more central to a POS plan. The member may need to choose or work through an in-network primary care provider who coordinates specialty care according to the plan’s rules.
Do not assume every POS policy works identically. Provider access, referral requirements, out-of-network benefits, deductibles, and cost-sharing can differ by insurer and plan. Always verify the actual plan documents.
PPO vs. POS: Side-by-Side Comparison
| Feature | PPO | POS |
|---|---|---|
| Full name | Preferred Provider Organization | Point of Service |
| In-network care | Generally costs less than out-of-network care | Generally costs less than out-of-network care |
| Specialist referral | Generally not required | Generally required through the primary care doctor |
| Primary care coordination | Usually less central to accessing specialists | More central to the plan’s care-access structure |
| Out-of-network care | Generally available at additional cost | Commonly may be available at higher cost, depending on plan terms |
| Prior authorization | May be required for certain services or prescriptions | May be required for certain services or prescriptions |
| Main appeal | Greater provider and specialist flexibility | Primary-care coordination while retaining potential flexibility outside the network |
The Biggest Difference: Specialist Referrals
For many consumers, the referral rule is the most noticeable practical difference between PPO and POS coverage.
With a PPO
You generally can make an appointment with a specialist without first obtaining a referral from your primary care physician. This can simplify access if you regularly see a dermatologist, cardiologist, orthopedist, neurologist, or another specialist.
With a POS Plan
HealthCare.gov states that POS plans require a referral from your primary care doctor to see a specialist. The primary care doctor therefore plays a greater role in coordinating care.
Failure to follow applicable referral rules can affect whether services are covered or how much you pay. Federal protections and plan-specific exceptions may apply to certain types of care, so consult the plan’s current documents rather than relying only on the general POS label.
Referral vs. Prior Authorization
A referral and prior authorization are related to accessing health care, but they are not the same thing.
- Referral: HealthCare.gov defines a referral as a written order from a primary care doctor for a patient to see a specialist or receive certain medical services.
- Prior authorization: This is approval from the health plan that may be required before a service or prescription can be covered.
A PPO’s lack of a routine specialist-referral requirement does not mean every service can be obtained without insurer approval. PPOs and POS plans may require prior authorization for certain procedures, treatments, prescription drugs, imaging, or other services.
Prior authorization is not a guarantee of payment. HealthCare.gov specifically notes that preauthorization does not promise that a health plan will ultimately cover the cost. Other policy requirements still apply.
How PPO and POS Networks Work
Both PPO and POS plans use provider networks. A network consists of doctors, hospitals, facilities, and other providers that contract with the health plan.
Using an in-network provider generally costs less because the provider has agreed to the plan’s negotiated arrangements. Going out-of-network can result in higher deductibles, coinsurance, or other expenses depending on the policy.
The plan label alone does not tell you whether your preferred doctor is covered. Two plans from the same insurance company can have different networks. A hospital may participate in one network but not another, and participation can also change over time.
Verify the exact plan network. Search using the specific plan name or plan ID when possible, and confirm important doctors and facilities with the insurer. Do not rely only on a provider saying that it “accepts” the insurance company.
Why Out-of-Network Care Can Cost Much More
The ability to use an out-of-network provider does not mean the financial result will resemble an in-network visit. CMS explains that people usually pay more when they receive care from an out-of-network provider under a plan that covers such services.
Depending on the plan and applicable law, out-of-network care can involve:
- A separate or higher deductible.
- Higher coinsurance or other cost-sharing.
- Different reimbursement based on the plan’s allowed amount.
- Potential charges above the insurer’s allowed amount where balance billing is permitted.
- Costs that may not count toward the plan’s in-network out-of-pocket maximum.
Federal surprise-billing protections apply in specified situations, including certain emergency services and certain out-of-network services received at in-network facilities. Those protections do not turn all elective out-of-network care into in-network care or guarantee that every out-of-network service has the same cost-sharing as an in-network service.
PPO vs. POS Costs
Neither PPO nor POS coverage is automatically cheaper. A plan’s total cost depends on much more than its network label. When comparing plans, consider both the monthly premium and what you may pay when you actually receive care.
Premium
The premium is the amount charged for maintaining health coverage. You generally pay it whether or not you receive medical care during that month. Do not assume one plan type always has a lower premium than the other.
Deductible
A deductible is the amount you pay for certain covered services before the plan begins paying according to its terms. Plans can have different deductibles for different types of care, and out-of-network benefits may be subject to different requirements.
Copays and Coinsurance
A copay is generally a fixed amount charged for a covered service, while coinsurance is generally a percentage of the applicable cost that the member pays. Different plans may use either or both forms of cost-sharing.
Out-of-Pocket Maximum
The out-of-pocket maximum limits what you pay for covered in-network services during the applicable plan year under the plan’s rules. HealthCare.gov notes that premiums, services the plan does not cover, out-of-network care, and costs above the allowed amount do not count toward the Marketplace plan’s in-network out-of-pocket limit.
Who Might Prefer a PPO?
A PPO may appeal to someone who places a high value on provider flexibility. Situations in which its design may be useful include:
- You regularly see multiple specialists and want to avoid routine referral requirements.
- You want the option to use an out-of-network provider when the plan permits it.
- A particular doctor or specialist you want may not participate in every available network.
- You prefer to arrange more of your own specialty care rather than having it coordinated through a primary care physician.
- The PPO’s actual premium, network, drug coverage, and cost-sharing fit your expected health care use.
Greater flexibility is useful only if the specific plan also has acceptable costs and includes the providers, facilities, and prescriptions you need.
Who Might Prefer a POS Plan?
A POS plan may appeal to someone who is comfortable using a primary care doctor as the main coordinator of health care while still wanting potential access to out-of-network benefits under the plan.
- You like having a primary care doctor coordinate referrals and specialty treatment.
- Your preferred doctors and facilities participate in the POS network.
- You are comfortable following referral procedures before receiving specialty care.
- The plan provides an out-of-network option that is useful for your circumstances.
- Its actual premium and cost-sharing compare favorably with other plans available to you.
How to Compare a PPO and POS Plan
1. Check Your Doctors and Hospitals
Look up your primary care doctor, specialists, preferred hospital, laboratories, imaging centers, and other important providers in the specific plan’s network. Provider networks can differ even between plans offered by the same insurer.
2. Review Specialist Referral Rules
If you frequently see specialists, determine whether referrals are required, which provider must issue them, how long they remain valid, and whether special rules apply to particular services.
3. Compare Out-of-Network Benefits
Do not stop at whether out-of-network care is technically covered. Compare the applicable deductible, coinsurance, allowed-amount rules, potential balance-billing exposure, and any separate limits or exclusions.
4. Compare Total Costs
Look at the premium, deductible, primary care copay, specialist cost-sharing, prescription costs, hospital cost-sharing, and out-of-pocket maximum rather than focusing on one number.
5. Check Prescription Drug Coverage
A favorable medical network does not guarantee favorable prescription coverage. Review the plan’s formulary, pharmacy network, drug tiers, prior authorization requirements, and other applicable restrictions for medicines you use.
6. Read the Summary of Benefits and Coverage
HealthCare.gov explains that individual and job-based health plans provide a Summary of Benefits and Coverage, or SBC, designed to help consumers make apples-to-apples comparisons. Use the SBC along with the provider directory, drug formulary, and full plan documents when choosing coverage.
Common PPO vs. POS Comparison Mistakes
Assuming a PPO Is Always More Expensive
Plan type alone does not determine the premium. Prices depend on the particular plans available and applicable rating rules. Compare actual premiums rather than relying on a generalization about PPO or POS pricing.
Assuming Out-of-Network Means Affordable
A plan may technically cover out-of-network care while requiring substantially more cost-sharing. Check the actual reimbursement rules before deliberately using a nonparticipating provider.
Checking the Insurer Instead of the Exact Network
A provider may participate with an insurance company but not with every network that company offers. Verify participation using the exact plan.
Confusing Referrals With Prior Authorization
A PPO member who does not need a primary care referral may still need prior authorization from the insurer for certain care. Conversely, receiving a referral under a POS plan does not necessarily eliminate other plan requirements.
Choosing Based Only on the Premium
A lower-premium plan can still cost more overall if it has a higher deductible, less favorable specialist costs, a narrower useful network, or less favorable prescription coverage for your needs.
Frequently Asked Questions
The Bottom Line
PPO and POS plans both use provider networks and generally reward members financially for receiving care in-network. The primary difference is access: PPOs generally provide more freedom to see specialists without referrals, while POS plans place greater emphasis on primary-care coordination and specialist referrals.
The biggest risk is choosing from the plan label alone. A PPO can have an unsuitable network or high out-of-pocket costs, while a POS plan may work well if its doctors, referral structure, and costs fit your needs. Before enrolling, compare the exact provider network, referral and prior-authorization rules, prescription formulary, premium, deductible, copays, coinsurance, out-of-network terms, and out-of-pocket maximum.
