Using Insurance for Rehab

Last reviewed 2026-08-01

Most private health plans are required to cover substance use disorder treatment as an essential health benefit under the Affordable Care Act, at parity with medical/surgical benefits under the Mental Health Parity and Addiction Equity Act.

What that means in practice

In practice, coverage still varies by plan: which levels of care are covered, how many days, and which providers are in-network. Before choosing a program, call the number on the back of the insurance card and ask specifically about substance use disorder / behavioral health coverage — the answer for a general medical question won't necessarily apply.

In-network vs. out-of-network

In-network treatment is almost always cheaper out of pocket. Many treatment centers have a dedicated admissions or verification-of-benefits team that will check coverage on your behalf before you commit to anything.
