Using Aetna Insurance for Addiction Rehab in Texas

If you or someone you love is struggling with addiction, the cost of addiction treatment should not stand in the way of getting help. If you carry an Aetna health insurance plan, you already have access to coverage that can help pay for drug and alcohol rehab in Texas.

Aetna is one of the largest health insurance providers in the United States, serving over 39 million members through a network of more than 1.2 million healthcare professionals and 5,700 hospitals. The company has been in operation since 1853 and now operates as part of CVS Health. Most Aetna plans include behavioral health benefits that cover substance use disorder treatment across every level of care.

Greenhouse Treatment Center in Grand Prairie, Texas, is in-network with Aetna. That means you get lower out-of-pocket costs, direct billing, and a streamlined admissions process. This guide explains what Aetna covers, how to verify your benefits, and how to begin treatment as soon as today.

Does Aetna Cover Substance Abuse Treatment?

Yes, Aetna does provide insurance that covers substance abuse treatment. Aetna marketplace insurance plans are required by the Affordable Care Act (ACA) to provide coverage for mental health and substance use disorders.^1,2

Additionally, both the ACA and the Mental Health Parity and Addiction Equity Act require the coverage for mental health and substance use care to be equitable to the coverage provided for medical/surgical services.²

The ACA also protects you from being denied coverage for a preexisting condition. This means that even if you were struggling with a substance use disorder prior to obtaining your current healthcare coverage, you should be covered for treatment.³

The exact amount and type of coverage that you’ll have will depend on your specific plan. Aetna offers many plans, including:⁴

• PPO plans: These plans typically allow for patients to seek specialty services without a referral from a primary care physician (PCP).
• HMO plans: These plans usually require your PCP to guide your care by providing referrals.
• Elect Choice plans: These plans utilize a PCP to guide care and require patients to stay in a specific network when receiving care.

Each Aetna plan has unique coverage details. For example, while some plans may require you to visit your PCP prior to reaching out to a substance use disorder facility, others may not. Each plan will also provide different amounts of coverage for rehab.

Does Aetna Cover Drug and Alcohol Rehab in Texas?

Yes. Aetna covers addiction treatment as part of its behavioral health benefits. The Affordable Care Act (ACA) classifies substance use disorder treatment as an essential health benefit. All Aetna marketplace plans and most employer-sponsored plans must include coverage for drug and alcohol rehab.

The Mental Health Parity and Addiction Equity Act (MHPAEA) adds further protection. This federal law requires Aetna to cover addiction and mental health services at the same level as medical and surgical care. Aetna cannot charge higher copays, impose stricter visit limits, or require more burdensome prior authorization for behavioral health compared to physical health services.

The ACA also protects you from being denied coverage for a preexisting condition. If you had a substance use disorder before obtaining your current Aetna plan, you are still entitled to treatment coverage.

In Texas, state parity laws enforced by the Texas Department of Insurance (TDI) provide an additional layer of protection for fully insured plans. Your exact coverage amount depends on your specific Aetna plan, but the law ensures you have meaningful access to treatment.

How to Use Your Aetna Insurance to Pay for Rehab in Texas

Using Aetna to pay for treatment at Greenhouse is a straightforward process. Here is what to expect:

Step 1: Verify Your Benefits

Call Greenhouse at or fill out the free, confidential online insurance verification form. An admissions navigator will confirm your in-network status, review your deductible and coinsurance, and explain your expected costs.

Step 2: Get a Referral (If Required)

If you have an Aetna HMO or Elect Choice plan, you will likely need a referral from your PCP before starting treatment. The Greenhouse team can help coordinate this. PPO and Open Access plans generally do not require referrals.

Step 3: Prior Authorization

Aetna typically requires prior authorization for inpatient and residential treatment. Because Greenhouse is in-network, the clinical team handles all authorization paperwork for you. Aetna uses the ASAM Criteria and its own LOCAT (Level of Care Assessment Tool) to determine medical necessity.

Step 4: Begin Treatment

Once benefits are verified and authorization is secured, you can begin care. Greenhouse offers same-day admissions when clinically appropriate. A utilization manager communicates with Aetna throughout your stay to ensure continued coverage. Learn more about what to expect as a patient.

How Much Does Addiction Treatment Cost with Aetna Insurance?

Your out-of-pocket cost depends on your Aetna plan, the level of care you need, and how much of your deductible you have already met for the year. Here are the main factors:

• Annual Deductible: The amount you pay before Aetna begins covering your treatment. Behavioral health and medical services share the same deductible.
• Copay: A flat fee due at each visit or service. Some Aetna copay-only plans guarantee that all post-deductible costs are copays.
• Coinsurance: Your percentage share of costs after the deductible. For example, you might pay 20% while Aetna covers 80%. In-network coinsurance is significantly lower than out-of-network.
• Out-of-Pocket Maximum: The annual cap on what you pay. Once you reach this limit, Aetna covers 100% of covered services for the rest of the year.
• In-Network vs. Out-of-Network: In-network facilities like Greenhouse have negotiated rates that keep your costs lower. Out-of-network care may carry coinsurance rates of 30% to 50% or may not be covered at all depending on your plan.
• Length and Level of Care: More intensive treatment (detox plus residential) costs more than outpatient therapy alone. Research shows longer treatment produces better outcomes, so the investment is meaningful.

Greenhouse offers additional payment options for costs not covered by insurance, including financing plans and family support. Call  to discuss your options.
