Insurance coverage can make a big difference in how much you pay for addiction treatment. What’s covered depends on factors such as the specific plan type, whether the facility is in-network or out-of-network and how your benefits work. Whether the care is considered medically necessary or if you need prior authorization from the insurance company can also impact coverage.

In this guide, you’ll learn how Aetna benefits typically apply to addiction treatment, what it means to be in-network vs. out-of-network and how to verify your specific coverage and potential out-of-pocket costs.

Does Aetna Cover Drug and Alcohol Rehab?

Many Aetna plans include drug and alcohol rehab, but whether these services are covered and how much you might have to pay out of pocket depends on your policy.

Factors that can affect coverage include:

  • In-network vs. out-of-network coverage. Aetna generally covers a greater share of the cost of rehab programs within its network. However, out-of-network coverage can provide help when in-network care options aren’t enough. If your insurance covers part of out-of-network rehab treatment, the coverage is often lower, and there may be exclusions.
  • Plan type. HMOs, PPOs, EPOs and POSs have different coverage requirements.
  • Prior authorization and referrals. Some plan types may require the rehab to obtain prior authorization from the insurance company for your benefits to cover your care. You may also be referred for treatment by your primary care physician or another healthcare provider.
  • Medical necessity. In some cases, you may have to prove the care is medically necessary for it to be covered. For example, your insurer might cover medication-assisted treatment for safe withdrawal management, but not equine therapy.
  • Deductible and out-of-pocket max. If you’ve already met your deductible or out-of-pocket max for the year, your insurance may pay a higher percentage of the treatment cost.

How Aetna Addiction Treatment Coverage Typically Works

For insurance purposes, addiction treatment is generally divided into two main categories: inpatient and outpatient care. Inpatient refers to residential programs or hospitalizations where you live on-site, and outpatient is for everything else.

Insurance may cover common levels of care, such as detox or residential rehab, as well as specific treatment types, such as individual therapy or medication-assisted treatment. Many plans cover substance use and mental health treatment as part of required benefits categories, but the details are plan-specific.

What Types of Addiction Treatment Might Be Covered?

Addiction treatment programs are as varied as the addictions themselves. What you need to support long-term recovery depends on your background, triggers and goals. Aetna may cover the following treatment levels and services.

Medical Detox

Detox is often the first step in the rehab process and can help you get medically stable so your body and mind are ready to focus on long-term recovery. Aetna coverage for medical detox generally depends on the level of care provided and length of stay, and prior authorization may be required.

Inpatient or Residential Rehab

Inpatient residential drug and alcohol rehab programs provide around-the-clock structured care and support. Aetna plans typically require prior authorization for inpatient rehab care, and length-of-stay reviews may be necessary to show that treatment is progressing.

Medication-Assisted Treatment (MAT)

Medication-assisted treatment may be covered under both medical and pharmacy benefits. Your plan may have specific formulary requirements, and prior authorization may be required, particularly if your healthcare provider wants to use a brand-name drug.

Therapy and Counseling

Aetna plans that provide behavioral health benefits may pay for therapy and counseling services that are part of your rehab program. Coverage may depend on whether the therapeutic approach is evidence-based and whether it’s individual, group or family counseling.

Dual Diagnosis Support

When someone has both a substance use disorder and a mental health disorder, it’s called dual diagnosis. While many rehabs don’t provide standalone mental health treatment, they do provide care for those with co-occurring mental health conditions, such as anxiety, depression or post-traumatic stress disorder (PTSD). Some dual-diagnosis services may be billed under behavioral health coverage and reviewed for medical necessity, so coverage varies.

Aftercare and Continuing Support

Some Aetna plans may cover step-down services or aftercare support. Coverage is often dependent on what the rehab’s overall support model includes and what’s billable to insurance.

In-Network vs Out-of-Network Insurance Coverage

Understanding the differences between in-network and out-of-network insurance coverage can help set accurate coverage expectations and prevent surprise bills. When a rehab center is in-network, it usually means they’ve negotiated rates with the insurance company, and your share of the bill, such as with a co-pay or coinsurance, is lower. Out-of-network rehabs may have higher coinsurance percentages or require a separate deductible.

In some cases, even an in-network facility may provide services that involve out-of-network providers. It’s important to understand who bills for what and whether any services may be out-of-network during the insurance verification process.

What Affects Your Out-of-Pocket Costs with Aetna?

Your out-of-pocket costs for substance use disorder treatment with Aetna insurance depend on your:

  • Deductible. Your deductible is the amount you have to pay, usually in a calendar year, before your insurance kicks in. There may be individual and family deductibles, depending on the policy.
  • Co-pay and coinsurance. This is your share of the cost, excluding the deductible.
  • Out-of-pocket maximum. Once you reach this amount, your insurance should cover all care under your policy in full.
  • Admission timing and benefit period. If you’re admitted to rehab during your benefit period, costs may be impacted by whether you’ve met your deductible and your share of the costs.
  • Length of stay and level of care. Out-of-pocket costs are generally higher the longer you’re in treatment and the higher the level of care.

Types of Aetna Plans

Aetna offers several plan types, each with a different structure that can affect your coverage and out-of-pocket rehab costs:

  • Health maintenance organization (HMO). This plan type generally requires you to use in-network care providers and centers. You may also need a referral for any specialist treatment.
  • Preferred provider organization (PPO). With a PPO, you can seek care from any provider, but there may be differences in what’s covered for in-network and out-of-network care.
  • Exclusive provider organization (EPO). EPOs are similar to HMOs, except they don’t usually require referrals to see specialists. Out-of-network coverage is generally limited to medical emergencies.
  • Point-of-service (POS). These policies are similar to PPOs in that they generally offer coverage for both in- and out-of-network care, but you may need a referral to see a specialist.

If you’re not sure what kind of policy you have, you can check your insurance card, review your Summary of Benefits and Coverage statement or log in to the member portal for more details.

How to Verify Your Aetna Benefits for Drug and Alcohol Recovery

You can verify your Aetna benefits for drug and alcohol recovery by contacting the insurance company or letting the rehab program verify for you.

DIY Verification Steps (Member)

  1. Call the member services number on the back of your Aetna insurance card.
  2. Ask whether the rehab program you’re considering is in-network or out-of-network for your plan.
  3. Find out if there are any authorization requirements for your level of care.
  4. Ask about how your deductible, coinsurance, co-pays and out-of-pocket max may apply.
  5. Ask about any limits, such as the number of days you can be in treatment or whether certain services must be deemed medically necessary.

Fastest Option: Let a Rehab Verify for You

In most cases, the easiest way to find out what your Aetna policy pays for rehab is to let the addiction treatment program verify your benefits. You provide your insurance information, including your policy number, and the rehab confirms whether it’s in- or out-of-network and which benefits apply. Keep in mind that this verification process can provide important information, but Aetna will determine your final coverage.

What to Do if Coverage Is Limited or Denied

If you find out your coverage is limited or your authorization request was denied, you aren’t out of options. Start by asking for the reason for the denial and information about any appeal process that might be available to you. Request the required document list and determine whether a peer-to-peer or clinical review is available.

If coverage was denied because the rehab program isn’t in Aetna’s network, you may be able to ask for a single-case agreement. This is when the insurance company agrees to work with the rehab and negotiate rates and coverage on a one-time basis.
