There’s an increase in cases of alcohol use disorder, opioid use disorder, and substance use disorder (SUD) in the US. This increase has led to the rising need for accessible drug rehab services.
Some drug rehab services are expensive. You may find it challenging to meet treatment costs on your own. A reliable insurance plan relieves this financial burden. You can rest assured that the services you need are covered. Aetna is one of the largest health insurers. It serves tens of millions of Americans, offering broad behavioral health coverage in its individual, employer-sponsored, Medicare, and Medicaid plans.
This article will help you understand how to get the most out of your Aetna drug rehab benefits, from coverage types to cost-sharing strategies. If you or your loved ones need help with insurance verification or treatment, please get in touch with our team at Nirvana Recovery. We’re experts in insurance verification and treatment coordination.
Therapy Programs: Include individual/group/family therapy, coping skills, and relapse prevention planning
24/7 Supervision: Staff support is available for safety; residents get emotional stabilization in a distraction-free environment
Aetna determines whether inpatient/residential treatment is medically necessary based on the following:
High Relapse Risk: The patient cannot maintain abstinence in a less intensive setting
Unstable or Unsupportive Home Environment: The patient may be exposed to substances or have no reliable recovery support at home
Outpatient and Intensive Outpatient Programs (IOP)
Standard outpatient includes weekly individual/group/family therapy, psychiatric evaluation, and medication management. An intensive outpatient program is a higher level of outpatient care, with 3-5-hour sessions for several days a week.
Aetna covers standard outpatient and IOPs when medically necessary and delivered by licensed providers. IOPs are more expensive than standard outpatient due to their intensity and the length of sessions.
Outpatient therapy is recommended when your condition is stable; an IOP is recommended when you have more significant symptoms that interfere with daily functioning.
Partial Hospitalization Programs (PHP)
A partial hospitalization program is an intensive form of outpatient treatment designed for people who require more support than what an IOP offers but do not need 24-hour inpatient care. It’s a structured daytime treatment option and a step-down from inpatient care. PHPs run 4 to 8 hours per day, 3 to 5 days a week.
A PHP is recommended when you’re experiencing conditions that interfere with daily functioning but don’t require 24-hour supervision. Aetna covers partial hospitalization programs.
Medication-Assisted Treatment (MAT)
Aetna covers the following medications commonly used in MAT:
Buprenorphine: Reduces cravings and withdrawal symptoms. Aetna has removed pre-authorization requirements for buprenorphine products in employer-based plans.
Methadone: Used in opioid treatment programs (OTPs). Coverage is provided through medical plans rather than pharmacy benefits, since methadone is administered in OTPs.
Naltrexone: Available in oral and extended-release injectable forms. Generic versions are covered, while the brand Vivitrol injection may have higher out-of-pocket (OOP) costs.
Naloxone: Used to reverse opioid overdoses. Aetna covers various forms, including nasal sprays and injectable formulations.
Counseling and Behavioral Therapy
Aetna covers the following types of therapy services:
Individual Therapy: Personalized sessions addressing co-occurring conditions like depression, anxiety, and trauma
Group Therapy: Facilitated sessions focusing on shared experiences and coping mechanisms
Family Therapy: Sessions aimed at improving communication and resolving conflicts within families
Telehealth and Virtual Counseling: Remote therapy sessions
Aetna also covers evidence-based approaches like the following:
Cognitive behavioral therapy (CBT)
Dialectical behavior therapy (DBT)
Motivational interviewing (MI)
Contingency management
Aftercare and Relapse Prevention
Aetna covers aftercare support services, which are essential for maintaining sobriety and preventing relapse after intensive treatment. Some of these services include:
Sober Living: Aetna may not cover housing arrangements, but it may cover clinical services received in these environments
Life Skills Training: Includes programs that enhance coping mechanisms, stress management, and other essential skills for daily living
Family Therapy: Sessions are aimed at repairing relationships and building a strong support system
Aetna also covers relapse prevention services that help you maintain your recovery. They include the following:
Individual counseling
Group therapy
Behavioral therapies
Steps to Maximize Your Aetna Rehab Benefits
Review Your Plan Documents Thoroughly
Your Summary of Benefits and Coverage (SBC) has a cost-sharing table, which outlines coverage levels. You’ll find information on copays, deductibles, and coinsurance for services like inpatient rehab or partial hospitalization. Review “What the plan covers” and “Your cost if you use in-network vs. out-of-network provider” sections.
Your SBC includes a “Limitations & Exceptions” section, which lists services that have caps, visit limits, and exclusions. Confirm the types of covered SUD services. Aetna covers a range of addiction treatment services, including the following:
In-network facilities and providers have contracted with Aetna to provide discounted rates. Thus, your billed amount is capped. These facilities and providers are prohibited from billing you above the capped rate. You should expect no surprise charges. You also get lower deductibles and coinsurance percentages.
In-network providers handle pre-authorization on your behalf, reducing paperwork and simplifying the process for you.
Out-of-network providers set their own rates, which are usually higher than Aetna’s. You should expect higher deductibles and coinsurance rates. You may also have to manage pre-authorization and file claims yourself.
Get Pre-Authorization Early
The following are reasons why early pre-authorization prevents delays or claim denials:
It confirms medical necessity before care is provided. Aetna uses prior authorization to confirm that the requested level of care meets its medical necessity criteria.
It allows you to prepare based on network status. Prior authorization clarifies whether the proposed provider or facility is in-network. If not, you get time to choose an in-network facility or request an exception before treatment begins.
It speeds up claims processing. Authorization information is usually needed during claims processing. Documenting approvals reduces claim denials.
Use All Available Services
Medication-assisted treatment (MAT) treats the biological component of addiction. Therapy treats the behavioral and cognitive components. Moreover, aftercare addresses social needs and relapse risk. Together, these components reduce overdose risk and improve the chances of long-term recovery. Here’s why a comprehensive approach works:
MAT is life-saving. It lowers overdose and relapse risk.
Therapy treats co-occurring mental health issues, teaches coping skills, and helps overcome triggers.
Harm reduction and overdose prevention lower immediate mortality.
Aftercare and relapse prevention reduce the risk of relapse and support long-term recovery.
Coordinate Care Between Providers
Here’s what Aetna looks for in ongoing treatment plans:
Evidence-Based Criteria: Aetna relies on recognized standards to determine medical necessity. These include the American Society of Addiction Medicine (ASAM) Criteria and MCG guidelines.
Comprehensive Diagnostic Evaluation: Before starting or continuing care, Aetna expects a complete assessment. It includes current diagnoses and evidence that the proposed treatment is goal-oriented and medically necessary.
Continuing Stay Reviews: To extend coverage for inpatient/residential services, providers must submit a continued stay review before the initial authorization ends.
Adherence to Pre-Authorization Rules: Aetna lists the services that require prior authorization, including many behavioral health and SUD services.
Cost-Saving Tips When Using Aetna for Rehab
Meet Your Deductible Strategically
Your deductible is the amount you pay for covered health care services before your insurance starts to pay. Once you’ve met your deductible, you’ll pay coinsurance (a percentage of the cost) for covered services until you reach your OOP maximum. When you reach this limit, your Aetna plan pays 100% of covered services.
You can schedule your treatment early or late in the year. Timing towards the end of the year allows you to:
Apply any remaining deductible balance from the current year
Utilize your OOP maximum for the year
Reduce the financial burden for treatments that continue into the new year
Starting treatment early in the year allows you to maximize the use of your OOP maximum throughout the year.
Combine EAP and Aetna Benefits
An Employee Assistance Program (EAP) is an employer-sponsored benefit that offers employees and their families access to free, short-term counseling and support services. EAPs help you address personal issues that may affect your work performance or overall well-being.
You can schedule your sessions toward the end of the year if your EAP offers a set number of sessions per issue. This timing allows you to utilize the current year’s allocation, which may reduce the need to meet your deductible in the new year. You can also start treatment early in the year. It can help you spread out costs and manage your health care expenses more effectively.
Ask About Case Management Services
Aetna assigns case managers to members with complex, chronic, or high-cost needs. Case managers can be registered nurses, social workers, or behavioral health specialists. They do the following:
Conduct assessments that include medical, behavioral, and social factors
Coordinate care across providers (e.g., therapists or physicians)
Help navigate benefits, referrals, and resources in your community
Case managers guide you toward appropriate outpatient or in-network care. They may discourage emergency services or costly inpatient options. Case managers can also help in the following ways:
Clarify billing issues
Ensure care saves time and money
Engage with local resources like community support or financial aid programs
Common Challenges and How to Overcome Them
Denied Claims
Here are common reasons why Aetna may deny claims:
Lack of medical necessity. Aetna may determine that a service isn’t medically necessary for your condition.
Failure to get pre-authorization. Certain services require prior approval from Aetna. Without this authorization, Aetna may deny claims.
Use of out-of-network providers. Some plans may not cover services rendered by out-of-network providers.
Incomplete or incorrect documentation. Insufficient medical records or missing documentation can result in claim denials.
You can appeal denied claims by doing the following:
Review the denial letter to understand the specific reason for the denial
Collect relevant medical records and any other documents that can support your case
Try resolving the denial informally
If informal resolution doesn’t work, submit a formal written appeal
Coverage Caps and Limits
Aetna may have duration or visit limits on different services. For example, 30, 60, or 90 visits per year for some therapies. Some high-intensity services, like inpatient treatment, may require pre-authorization. These authorizations specify an initial number of days or sessions and require reviews for extensions.
Outpatient individual therapy often has fewer visit limits but may require documentation of medical necessity for extended or frequent sessions. Some employer or group plans show clear visit caps in their SBCs. Authorizations for PHPs cover several days per week or several weeks per month. These authorizations must be renewed with clinical updates.
Aetna has made it easy to access some medications used in MAT. However, quantity limits or prior authorization may still apply for other medications or for Medicare/Medicaid members.
Out-of-Network Restrictions
You can request a network gap exception so that Aetna covers out-of-network services at in-network rates. You can do so due to the following factors:
There are no available in-network providers with the necessary expertise or specialization
In-network providers are not accessible within a reasonable distance
Emergency care is essential, and waiting for an in-network provider is not possible
Do the following to request a network gap exception:
Contact Aetna member services through the number on your Aetna ID card.
Ask where and how you can submit a letter or form detailing the service you need, and the reason in-network providers are unavailable or insufficient. Include any supporting medical records.
Myths About Aetna’s Drug Rehab Coverage
“Aetna Only Covers Short-Term Rehab”
Aetna does not cover only short-term rehab.
Aetna uses established guidelines like the ASAM Criteria or MCG to determine medical necessity. Aetna judges whether a particular level of care and length of stay are needed. If the clinical facts align with the standards, Aetna may authorize continuing days or weeks of care.
While the initial authorization may be time-limited, Aetna may need continued-stay reviews to extend the authorization.
“MAT Isn’t Covered”
Aetna covers MAT and medications used in this service.
Coverage details depend on the specific Aetna plan (employer-based, Medicare, or Medicaid) and the exact drug formulation. These details include prior authorization, quantity limits, and whether a medication is on your plan’s formulary.
MAT authorizations and continued coverage are strengthened when counseling/therapy is documented alongside medication.
“You Can’t Switch Between Levels of Care”
Aetna allows you to switch between levels of care.
Clinical need determines the movement between levels of care, not a specific rule. If your status improves, a less intensive level, like standard outpatient, may be clinically appropriate. Your treatment team may thus request a step-down authorization. Aetna reviews the request for medical necessity.
Treatment failure at a lower level can similarly justify a step-up.

Frequently Asked Questions (FAQs)
Will I Need Pre-Authorization for Treatment?
You may or may not. It depends on the service, your specific Aetna plan, and state rules. High-intensity care, like inpatient/residential treatment or PHP, often needs pre-authorization. Standard outpatient treatment and some MAT medications like buprenorphine usually don’t require prior authorization.
Does Aetna Cover Detox Services?
Yes, Aetna covers medically necessary detox services. However, coverage depends on your specific plan, the level of medical need, and whether the facility or provider is in-network. The available detox services include the following:
Medically managed inpatient detox
Outpatient detox
Clinic-based opioid treatment
How Much Will I Pay Out-of-Pocket for Rehab with Aetna?
It depends. Aetna plans have varying deductibles, copays, coinsurance, and OOP maximums. After you meet your deductible, you pay coinsurance until your OOP maximum. Moreover, in-network providers have negotiated rates. Out-of-network care means higher OOP costs. Also, inpatient treatment and MAT may be more expensive than outpatient care.
What if My Preferred Rehab is Out-of-Network?
It means you may have to cover higher out-of-pocket costs and possible balance billing. However, Aetna may make a network gap exception at its discretion. They may also approve out-of-network care at in-network rates when medically necessary, in case of emergencies, or when no adequate in-network option exists.
How Quickly Can I Start Treatment with Aetna Approval?
Between the same day and several days. It depends on the following:
Whether the facility/program has an open bed or an IOP/PHP slot
Whether the authorization covers your planned start dates
Completion of medical screening and intake assessment
Whether there are any required pre-admission steps for MAT
