Rehab Centers That Accept EPO Insurance

Exclusive Provider Organization (EPO) insurance plan on a table

Published: June 19, 2025

Reviewed by Matthew N. Parker, MD

Understanding your insurance plan means that when you need rehab for addiction treatment, you can reduce some of the hassle of trying to find a facility. An Exclusive Provider Organization (EPO) plan is often seen as a good option because it falls somewhere between a Health Maintenance Organization (HMO) and a Preferred Provider Organization (PPO) plan. It offers some of the benefits of both.

Nearly half of the young adult population in the U.S., aged 18 to 25, struggles with mental health conditions or issues related to alcohol or drug addiction, according to a 2022 study. The percentages are lower for the next two age groups: ages 26 to 49 and those aged 50 and older. Unfortunately, many individuals across all age ranges either do not recognize that they need help or do not seek healthcare services for drug or alcohol rehabilitation. Although treatment programs are available, various challenges persist, including the stigma surrounding addiction, difficulties in obtaining health insurance coverage, and the struggle to find suitable substance abuse treatment even with insurance.

If these obstacles apply to you or a loved one, talk to your health care provider and insurance company about your options. Evidence-based treatment plans focus on total wellness, including inpatient and outpatient rehab, medication regimens, and cognitive behavioral therapy.

To learn more about EPO rehab coverage, how to find drug rehab that accepts EPO, and whether EPO addiction treatment is right for you, use this guide. RehabNet is a trusted resource that can help you get connected to the treatment you need and make sure it’s covered by your insurance policy.

About EPO Insurance

An Exclusive Provider Organization (EPO) plan uses a network of medical providers (hospitals, doctors, labs, etc.) to care for patients. Within this network, you can seek addiction treatment from specialists without needing a referral, most of the time. However, going out-of-network for non-emergency care can result in hefty medical bills. EPO plans won’t pay for care given by out-of-network facilities unless it’s an emergency, meaning you’re responsible for the total cost out-of-pocket.

Because EPOs have a wider network than HMOs, they’re a popular choice among people who want more flexibility in where they receive healthcare. A larger pool of providers may offer what you need in care while keeping premiums and deductibles lower than a PPO. The downside is that you must stay in-network to avoid costly medical expenses.

What Is the Difference Between an EPO, HMO, and PPO?

The differences between an EPO, HMO, and PPO will vary based on your area and which plan type you choose, but there are some generally defined traits for each health insurance plan.

HMO plans require a referral from a primary care physician (PCP) in order to see a specialist. In contrast, EPO and PPO plans typically do not require referrals. Both EPO and HMO plans have a defined network of providers and will only cover emergency out-of-network care. On the other hand, PPO plans will pay a reduced amount for out-of-network services, but they generally cover some costs.

HMOs have a set insurance coverage area that is usually smaller than that of EPOs. If you can’t find an in-network provider under an HMO or EPO, you’ll either have to forego that treatment or pay out-of-pocket. With a PPO, the range is more flexible, and you’ll still see some insurance benefits if the provider isn’t in-network.

Plan characteristics:

Referral policy:

  • EPO: No referrals required for specialists
  • HMO: Referrals required for specialists
  • PPO:No referrals required for specialists

Provider options:

  • EPO: Only in-network providers covered, except in emergencies
  • HMO: Only in-network providers covered, except in emergencies
  • PPO: Options for both in-network and out-of-network providers

Flexibility in coverage:

  • EPO: Moderate flexibility
  • HMO: Strictest option
  • PPO: Most flexible

With each plan type, there isn’t one that’s better. It’s more about what works best for your location, needs, and finances. Insurance plans purchased through the Healthcare Marketplace must offer coverage for mental health services as one of the ten essential benefits required by the Affordable Care Act (ACA).

Portions of rehab involve mental healthcare, and the usage of those benefits increases if you receive a dual diagnosis. Additionally, these plans can’t penalize you for pre-existing conditions. If you have a history of a substance use disorder (SUD), for example, you can still be eligible for coverage. Plans through Medicare and Medicaid will cover treatment for substance abuse under the ACA.

If your HMO, PPO, or EPO insurance for rehab is purchased privately or through an employer, there may be additional benefits or barriers to seeking care. The best insurance plan for rehab will be the one that does the most for your care. Speaking with your insurance company, reviewing the explanation of benefits (EOB) for your policy, or contacting RehabNet for support in verifying your insurance and connecting with a treatment center can all help you get the rehabilitation you need for recovery from drug or alcohol addiction.

The Benefits of an EPO Plan for Rehab

Seeking substance abuse disorder treatment with EPO insurance rehab access can be to your benefit. Your premiums will be lower than if you have a PPO, but your coverage area will be broader than it is with an HMO. You can choose a rehab facility without a referral under an EPO, which means fewer hoops to jump through before you can meet with a treatment provider.

If it fits your needs and your budget, EPO rehab benefits offer you flexibility for quality care while staying below the higher pricing of a PPO policy. Because the provider network is a dedicated list, it can be easier to know where you can receive care, as long as the insurance provider database is up-to-date.

Types of Rehab Services Covered by EPO Plans

Rehab services include a range of treatments that your healthcare team will choose from to create the best plan for your care. While alternative treatment options exist, this list covers the services most likely to be included in your policy.

Detox Programs

EPO detox services can be used for medical or social detoxification, but you should consult your plan to know which falls under your EOB. If your addiction requires medication to counter withdrawal symptoms, you’ll want to make sure your insurance covers it and what limits may apply.

Inpatient Rehab

Inpatient EPO rehab provides care around the clock for the initial stages of recovery. For more severe addictions, having a doctor and nurses monitor you 24/7 is an important part of preventing relapse and protecting your overall health. It removes you from people and places that may trigger the urge to use and ensures your body and brain are getting vital assistance. Individual and group therapy sessions also begin during residential treatment.

Outpatient Treatment

Outpatient addiction care with an EPO plan should mirror the basics of any other outpatient program. You receive medication support and mental health services at the level of care you require. A partial hospitalization program (PHP) can marry the benefits of inpatient and outpatient treatment by allowing you to receive in-hospital care part of the time while living at home as well. It’s often the next step after inpatient rehab to help you adjust as you heal.

Intensive outpatient programs (IOP) can follow inpatient rehab or a PHP. While a PHP can mean that you’re committed to spending 5-7 days a week in the program, an IOP reduces that amount to 3-5 days a week.

The next level in recovery is a less intensive outpatient program. You’ll still see a doctor regularly, attend group support meetings, and receive medication and counseling as needed, but your daily life will be impacted less by your recovery program. Maintaining sobriety requires commitment to your support team and its guidance, which often leans heavily on mental health treatment as you progress. If your previous housing puts you in danger of relapse, you might be placed in a sober living community to keep you on a healthier path.

Mental Health and Dual Diagnosis Programs

Support groups and individual therapy sessions improve your mental health by giving you coping skills and other tools to avoid relapsing. Getting dual diagnosis EPO coverage can further boost your resources when you’ve been diagnosed with both a SUD and another mental health disorder. Many may reach for alcohol or drugs when they’re struggling to handle challenges. Following the treatment plan designed by your healthcare providers means you have options beyond substance abuse to deal with whatever life brings.

Medication-Assisted Treatment (MAT)

Getting Medication-Assisted Treatment (MAT) with EPO insurance is determined by your specific plan. It should be covered as long as the provider is in-network, but you can double-check the information by contacting your insurance company. Opioid and alcohol addiction are the most common types treated with MAT, and some prescriptions may be required for the rest of your life to reduce relapse occurrence.

How to Use Your EPO Plan to Access Rehab

Using EPO for rehab may require a few actions on your part to avoid issues once you begin treatment. Ensuring that the rehab center you choose is in-network and that you can afford any out-of-pocket costs will reduce the stress that can lead to relapse.

Start by verifying that your plan will cover behavioral health or addiction treatment services. You can read your EOB or contact your insurer to confirm this information. Log in to your account to use your policy’s online database of in-network providers. Know that if this information is outdated, you may spend a lot of time trying to call incorrect phone numbers or speaking to providers that are no longer in-network. You’ll need to get verification from both your insurance company and the treatment facility that rehab services are covered before moving forward.

It’s important to note that no out-of-network care is covered under an EPO unless it is for emergency purposes. If you’re outside of your coverage area and decide to seek addiction rehabilitation, you’ll most likely be paying the entire cost out of pocket.

To offset the time it takes you to follow these steps, you can use RehabNet to find in-network rehab covered by your EPO. Helpful, licensed professionals are available 24/7 for EPO rehab insurance verification and EPO plan addiction treatment guidance. Our trusted services allow you to connect with help more easily and cut through the red tape of checking everything on your own.

How to Find Rehab Centers That Accept EPO Insurance

A common way to find EPO rehab centers is to use your insurance company’s directory, sometimes called a provider portal. You can search for EPO-accepted addiction centers that match your plan and locate their contact information. Using this tool can also help you understand what portion of the treatment is paid by your insurer.

When you have a list of provider options, you can call each addiction treatment center to verify that it accepts your EPO insurance. If you discover that many of them are no longer in-network (or sometimes even in business), you can call your insurance company using the number on your card to double-check the rehab network for your EPO.

If doing all of this on your own feels overwhelming, don’t let it be a barrier to seeking the care you need. Let a service like RehabNet make things easier. We can:

  • Look up rehab centers in your area that are covered by your insurance plan.
  • Verify that the rehab center you want accepts your insurance.
  • Put you in touch with a treatment placement specialist who can help you choose a program.
  • Compare facilities that accept EPO around the U.S.

Receive RehabNet EPO help to determine the best rehab option for your addiction, policy, and budget.

What to Expect from a Rehab Center That Accepts EPO Insurance

Your in-network rehab experience with an EPO policy should include treatment services that provide the necessary care for you to achieve and maintain sobriety. These can address behavioral health concerns, required medications, doctor appointments, and even life skills training and sober living practices.

With EPO network addiction centers, you shouldn’t need a PCP referral to access care. EPO treatment expectations should align with standard timelines that provide pre-approved services already counted in your policy. Whether a service is covered and how much should be answered before you begin treatment, by contacting your insurer or reading your EOB.

While rehab access with an EPO won’t be as wide-ranging as what’s offered under a PPO, it should efficiently meet your needs. Sometimes coordinating care in a smaller network makes things a little easier, especially if you get overwhelmed by longer lists of options. However, if you want EPO-accepted rehab quality to meet high-end or out-of-network luxury status, you may need to reconsider your priorities in policy coverage. These programs are more likely to be covered under a PPO option.

FAQs About EPO Insurance And Rehab

Does EPO insurance cover out-of-network rehab centers?

Only in emergencies. For flexibility with out-of-network care, you’d need a PPO policy. However, an EPO offers more choice in coverage than an HMO.

Do I need a referral for addiction treatment with EPO?

Not usually. One of the advantages of an HMO is that EPO policies allow you to choose a specialist without a PCP referral.

Can I use EPO insurance for inpatient and outpatient care?

Yes. Make sure to verify that the inpatient or outpatient facility is in your coverage area and any copays, coinsurance, and deductibles you may be responsible for paying.

How do I verify what services are covered by my EPO?

You can contact your insurance company directly, search their online directory, or use a service like RehabNet to confirm your coverage.

What if the closest rehab center is out-of-network?

Unfortunately, EPOs only cover out-of-network care for emergencies. If you want to use the closest rehab facility but it’s not covered by your insurance, you may need to either change your insurance plan or figure out how to pay for rehab on your own.
