What Does Aetna Cover for Rehab?

Aetna, now part of CVS Health, provides integrated behavioral health coverage for substance abuse treatment. Aetna plans cover all levels of addiction care as mandated by the Mental Health Parity and Addiction Equity Act.

Inpatient & Residential Treatment

Aetna covers medically supervised detoxification, short-term residential treatment, and long-term residential care when clinically indicated. Pre-authorization is required, and Aetna assigns a dedicated case manager to coordinate care throughout your treatment.

Outpatient Programs

Coverage includes intensive outpatient programs (IOP), partial hospitalization (PHP), individual therapy, group counseling, and family therapy. Aetna's behavioral health network includes thousands of providers specializing in addiction treatment.

Dual Diagnosis Treatment

Aetna covers integrated treatment for co-occurring mental health and substance use disorders. This includes comprehensive assessments, coordinated treatment planning, and simultaneous treatment of both conditions, which research shows leads to better outcomes.

How to Use Aetna for Addiction Treatment

Aetna offers several pathways to access addiction treatment, with dedicated behavioral health support to guide you through the process.

Contact Aetna Behavioral Health

Call the behavioral health number on your Aetna member ID card to speak with a representative who specializes in substance abuse treatment. They can help you understand your benefits, find in-network providers, and initiate pre-authorization.

Find Treatment Centers

Search Aetna's online provider directory for behavioral health facilities, or use our treatment center search to find Aetna-accepting rehab centers. In-network facilities will have lower out-of-pocket costs.

Appeals Process

If Aetna denies coverage for treatment, you have the right to appeal. Your treatment provider can submit additional clinical documentation supporting medical necessity. Aetna must respond to urgent appeals within 72 hours.

Aetna Insurance Verification Process

Aetna offers multiple ways to verify your substance abuse treatment benefits before admission.
