Federal law requires most insurance plans to cover addiction treatment. We verify your specific benefits free in minutes — so you know exactly what you'll pay before committing to any program.
Two landmark federal laws guarantee addiction treatment coverage for most Americans — and 2025 brought the strongest enforcement rules yet. Understanding these laws is the first step to accessing your benefits.
The MHPAEA prevents group health plans and insurance issuers from imposing less favorable benefit limitations on mental health and substance use disorder treatment than on medical and surgical benefits. This means your insurer cannot impose stricter limits, higher copays, or fewer covered days for addiction treatment than for a broken leg or cancer treatment.
The 2025 MHPAEA updates introduced tougher oversight, required insurers to demonstrate adequate behavioral health provider networks, and expanded mandatory MAT coverage — the most significant strengthening of the law since its passage. See the DOL MHPAEA resources →
The ACA classifies substance use disorder treatment as an essential health benefit — meaning all marketplace plans and most employer plans must cover it. Combined with MHPAEA, virtually every insured American has a legal right to addiction treatment coverage.
The ACA also extended MHPAEA protections to individual health insurance coverage in the marketplace, dramatically expanding the number of Americans with addiction treatment benefits. Check your marketplace plan benefits at Healthcare.gov →
