With the growing awareness of mental illness, more people in the U.S. are seeking long-term care focused on recovery. This has led to an increasing importance of mental health rehab. Effective mental health rehab fosters personalized therapy, medication management, and family support.
Aetna is a major health insurer that provides behavioral health benefits in many of its plans. Its benefits cover a range of services for mental health and substance use disorders (SUDs), including inpatient and outpatient rehab.
This article will help you understand what Aetna covers for mental health rehab. We will also discuss eligibility requirements and how to use benefits effectively. If you’re considering using Aetna or starting treatment, please reach out to our team at Nirvana Recovery. We’re an experienced partner in navigating Aetna insurance for treatment access.
Types of Mental Health Rehab Covered by Aetna
Inpatient Psychiatric Treatment
When assessing medical necessity, Aetna relies on established clinical tools, including the following:
MCG guidelines
The American Society of Addiction Medicine (ASAM) Criteria
Justification for inpatient psychiatric treatment includes:
Acute risk
Failure or inadequacy of outpatient care
Inability to self-care
The following services are included in inpatient psychiatric treatment:
Room and Board: Accommodations may be private or shared, covering a bed, meals, and basic amenities.
Medication Management: Includes psychiatrists or psychiatric pharmacists prescribing, adjusting, and educating about medications. It also includes monitoring side effects and treatment responses.
Therapy: Includes individual, group, and family sessions. Evidence-based approaches, like cognitive behavioral therapy (CBT), dialectical behavior therapy (DBT), and trauma-informed care, may be used.
Residential Treatment Centers (RTC)
Care in a residential treatment center involves living in a highly structured environment for an extended period. Programs offered are tailored to individuals whose conditions require more than what short-term or outpatient care can offer. These environments are designed for the following:
Those who haven’t responded adequately to outpatient therapy
Those who are under-supported at home
Those who require a safe, distraction-free setting to make meaningful progress
Aetna requires prior authorization before approving residential treatment. Thus, residential stay requests must be submitted and approved based on medical necessity before treatment can be covered.
Partial Hospitalization Programs (PHP)
A partial hospitalization programprovides a highly structured treatment. You live at home but spend 6 to 8 hours at a treatment center, several days a week. This program offers intensive support while allowing you to maintain family, school, or work commitments. A typical day may include the following:
Individual and group therapy
Psychoeducational sessions
Skill-building and practical life training
Medication management and psychiatric evaluations
Evidence-based approaches like CBT and DBT
Aetna covers in-network facilities that offer PHPs. However, coverage depends on prior authorization. Aetna evaluates eligibility for each case to confirm medical necessity.
Intensive Outpatient Programs (IOP)
An intensive outpatient program(IOP) is a structured, non-residential treatment option. It offers a higher level of care than weekly therapy but doesn’t require 24/7 supervision.
It’s recommended for people who need significant support beyond what standard outpatient therapy offers but who are stable enough to remain at home. It’s also ideal for someone who has moderate to severe mental health or substance use symptoms but doesn’t require hospitalization.
IOPs run for 9 to 19 hours per week. Sessions last for 2 to 4 hours and run for 2 to 5 days a week.
Aetna covers IOPs as part of its behavioral health benefits.
Outpatient Therapy & Counseling
Outpatient therapy/counseling involves receiving mental health or substance use support through scheduled sessions. You do not need overnight stays in a facility. It includes the following:
Individual Therapy: One-on-one sessions with a therapist. Sessions are customized to your recovery goals, history, and personal challenges.
Group Therapy: Sessions with peers facilitated by one or more therapists. Sessions focus on shared topics like coping skills or emotional processing.
Family Therapy: Involves family members. It addresses relational patterns, communication issues, enabling behaviors, and conflict resolution.
Some Aetna plans have annual limits for outpatient therapy visits. For example, 60 visits per year. Copays can range from $0 to $60 per visit, depending on your plan and location.
How to Verify Your Aetna Mental Health Rehab Benefits
Reviewing Your Summary of Benefits
You can find a link to the Summary of Benefits and Coverage (SBC) when you’re reviewing a plan and its prices. You can also find a link when you’re comparing plans after finishing your application. Alternatively, you can request a copy from Aetna at any time. You will also get the SBC when you apply for or renew your coverage.
Look for mental health coverage details under headings such as “Behavioral Health” or “Mental Health & Substance Abuse Services” in the coverage table. Review the section labeled “Outpatient Mental Health” or “Outpatient Behavioral Health” to see what’s covered.
You’ll find information about deductibles and out-of-pocket limits you’ll need to meet under the “Important Questions” section.
Contacting Aetna Member Services
Ask questions about the following:
Eligibility
Am I currently eligible for outpatient mental health benefits under my plan?
Are there any limits on how many therapy sessions I’m eligible for per year?
Do I need prior authorization to start therapy?
In-Network Providers
If my preferred provider isn’t in-network, can you help initiate a single-case agreement?
Do you have in-network specialists in a particular area (e.g., trauma counseling)?
Costs
What is my in-network deductible, and how much of it have I already met?
What’s the copay or coinsurance for each outpatient mental health therapy session?
After I meet my deductible, how does pricing change for both individual and group therapy?
Using a Treatment Center’s Insurance Verification Service
Handling insurance verification on your own can be time-consuming. You may also find it challenging to understand the information you get. That’s why you have Nirvana Recovery. Our admissions team can confirm benefits on your behalf. We have handled insurance verification for a long time and understand some of the things you may find complicated.
To get started, you’ll need to submit an insurance verification requestthrough our website. You can also call our team at (480) 764-2335. We will need the following information from you:
Your insurance provider (e.g., Aetna)
Your member ID
Your name and date of birth
Your contact information
Information on who is seeking treatment (if it’s not you)
The patient’s information (if it’s not you)
Understanding Pre-Authorization Requirements
Prior authorization requests include the following clinical documentation:
Clinical Records: Diagnosis, mental status examination, treatment history, and risk/safety assessment
Treatment Plan: Clear goals, approaches used, and anticipated duration
Assessment Tools: When applicable, they include the ASAM Criteria and MCG guidelines
Prior authorization begins with the initial request. If your stay is extended, your provider may submit a renewal request.
Aetna reviews and decides on routine, non-urgent requests within 14 days. Decisions for urgent requests, where delay could jeopardize your health, are made within 24 to 72 hours.
Aetna will send written notifications requesting more information if some of it is missing. Your provider has up to 14 days to respond. Once received, Aetna decides within 2 days.
Factors That Affect Aetna Coverage for Mental Health Rehab
Medical Necessity Determination
Aetna deems a service medically necessary if:
A qualified provider would provide it to diagnose, treat, evaluate, or prevent a disease, illness, or its symptoms
It aligns with established standards, is clinically appropriate, and is considered effective for the patient’s condition
It’s not provided for convenience and is not more costly than an effective alternative that could provide equal benefit
Aetna references the following established guidelines to determine medical necessity for behavioral health:
The ASAM Criteria for substance use disorder treatment
MCG Care Guidelines
In-Network vs. Out-of-Network Care
In-network providers accept Aetna’s lower contracted rates and do not charge more. Your costs are thus limited to deductibles and coinsurance only. In-network care also protects you from surprise charges for amounts above what Aetna pays.
Out-of-network deductibles and coinsurance rates are higher. You may also be charged the portion of the provider’s fees that exceeded Aetna’s “allowed” amount. That extra cost doesn’t count toward your deductible or out-of-pocket (OOP) maximum.
In-network providers have established relationships and familiarity with Aetna’s requirements. They may thus experience faster approvals. But out-of-network providers must get prior authorization, and they lack network agreements. This can make the process slower and more complex.
Length of Stay and Session Limits
Aetna may limit the number of days covered for inpatient or residential treatment. Coverage relies on ongoing review. Approval for extensions depends on justification that the current level of care is still medically necessary. Session limits for outpatient therapy are plan-specific. You may have annual therapy visit limits, like 14 or 30 visits per year.
After the initial authorization, if your provider determines that your treatment is still medically necessary, they can request additional days or sessions. Aetna grants extensions when:
The ongoing care aligns with clinical guidelines and best practices
There’s documented evidence that limiting further treatment would jeopardize recovery
Level of Care Transitions
Step-up care involves transitioning to a more intensive setting when the current treatment isn’t addressing acute or worsening symptoms. For example, moving from outpatient therapy to IOP or from IOP to PHP.
Step-down care involves transitioning from a higher-intensity service to a less intensive option as the patient stabilizes and improves. For example, moving from residential treatment to PHP or from IOP to outpatient counseling.
Aetna uses evidence-based assessments to determine when a level of care transition is appropriate. These assessments evaluate your current needs and help decide whether to authorize a transition. Aetna maintains coverage under the same plan as long as:
The new level of care is clinically appropriate and medically necessary
The care continues to fall under covered benefits within the policy
Common Challenges and How to Overcome Them
Claim Denials
The following are common reasons why Aetna may deny claims:
When it deems the service as not medically necessary
When you fail to get pre-authorization for services that require it
When you use a provider outside Aetna’s network
You have 180 days from the denial notice to submit an appeal, unless your plan states otherwise. You can start with a peer-to-peer review, in which your provider can discuss the case directly with Aetna’s clinical reviewer. If it doesn’t work, you can try calling Aetna member services; ask if the denial can be resolved informally. If it can’t, file a formal written appeal.
Coverage Limitations
Aetna covers evidence-based therapies like CBT and DBT. However, it may exclude other therapies unless deemed medically necessary and pre-approved. Restrictions may also apply depending on where care is delivered. For example, therapy in hospital-based outpatient departments may lead to higher costs or unexpected billing.
Here’s how you can navigate these restrictions:
Always confirm coverage up front. Review your plan documents or call member services.
Use medically necessary justification. For excluded therapies, request pre-authorization with supporting documentation. Show how the therapy is essential for your care.
In case of a denial, submit a detailed appeal with letters from your clinician emphasizing medical need.
Authorization Delays
Here are strategies to speed up approval:
Use electronic prior authorization (ePA) systems. These systems cut approval times significantly.
Prepare thorough and accurate documentation. Ensure your submission includes complete clinical documentation, correct diagnosis, and provider or facility identifiers.
Follow-up. Check with Aetna every 48-72 hours to prevent unforeseeable issues. Establish a direct line of communication (e.g., phone).
Request an expedited review for urgent cases. Let Aetna know that your request is urgent. Also, ask your provider to include a formal note explaining the clinical risks of delay.
Ensure that prior authorization is managed by someone experienced who keeps track of the needed documents and oversees submission and follow-ups.
Myths About Aetna’s Mental Health Coverage
“Aetna Doesn’t Cover Long-Term Rehab”
Aetna can cover long-term residential or inpatient rehab when the care is medically necessary, and your specific plan includes it. Coverage also depends on network status, prior authorization, and clinical documentation.
Aetna evaluates requests against its medical necessity rules. If the service meets those standards and the plan includes that benefit, it may be approved. Furthermore, long-term programs like residential treatment usually require prior authorization and ongoing reviews (for extensions).
“Only Severe Conditions Qualify”
Aetna does not limit coverage to only the severe cases. Medical necessity and criteria for the level of care drive coverage decisions. This means moderate conditions can qualify for higher levels of care, including IOP and PHP, when clinical evidence shows a higher intensity is needed.
Reviewers look for evidence that the requested treatment is appropriate, effective, and the least restrictive option.
“Outpatient Therapy Isn’t Covered”
Most Aetna plans include outpatient mental health benefits like individual, group, and family therapy. While coverage details may vary based on your specific plan, outpatient therapy is included. Outpatient therapy may involve the use of evidence-based approaches, such as CBT, DBT, and mindfulness-based cognitive therapy (MBCT).
