How to Pay for Rehab

Last reviewed 2026-07-18

Cost is one of the biggest reasons people delay getting help — but there are more ways to cover treatment than most people realize.

Insurance

Under the Affordable Care Act and the Mental Health Parity and Addiction Equity Act, most health plans sold on ACA marketplaces are required to cover substance use disorder treatment as an essential health benefit. Coverage details — which levels of care, how many days, what's in-network — vary by plan, so it's worth calling the number on the back of the insurance card before choosing a provider.

Medicaid and Medicare

Medicaid covers addiction treatment in every state, though the specific services and providers covered vary. Medicare Part A and Part B also cover substance use treatment, including inpatient and outpatient rehab.

If there's no insurance

Many treatment centers offer sliding-scale fees based on income, and SAMHSA-funded state programs exist specifically for people without coverage. The SAMHSA National Helpline (1-800-662-4357) can connect callers to free or low-cost options in their state.

This is general information, not a guarantee of coverage — always confirm details directly with the insurer or provider.
