Does Aetna Cover Addiction Treatment?

Aetna, a leading provider of health insurance in the United States, offers a wide range of healthcare products and related services, including medical, pharmacy, dental, behavioral health, group life, and disability plans. Founded in 1853 and headquartered in Hartford, Connecticut, Aetna is known for its comprehensive network and quality healthcare services. As of 2018, it operates as a subsidiary of CVS Health, a renowned retail pharmacy and healthcare company. Aetna strives to provide healthcare solutions that are both accessible and affordable, ensuring its members receive the necessary care to lead healthier lives.

Two federal laws make coverage for substance use disorder treatment close to universal in the United States. The Affordable Care Act lists mental health and substance use disorder services among the ten essential health benefits that individual and small-group plans must include. The Mental Health Parity and Addiction Equity Act of 2008 (MHPAEA) goes further: when a plan covers behavioral health, it may not impose financial requirements or treatment limitations more restrictive than those applied to comparable medical and surgical care.

What differs from member to member is not usually whether treatment is covered but how much you pay and what approval is required — and both come down to your specific plan, network status and deductible. The fastest way to find out is a benefits check, which takes a few minutes and costs nothing.

6,289 centers in our directory are listed as accepting Aetna. In-network status can change, so confirm it before admission.

Benefit Snapshot

This table describes general patterns in behavioral health benefits and is not a quote, not a guarantee of benefits and not specific to your plan. Coverage, prior-authorization rules and cost sharing vary by plan, state, network and product line — Medicare Advantage and Medicaid plans differ from commercial plans. Verify your benefits before admission.
