Rehab Cost by State: 2026 Treatment Cost Guides

Addiction treatment costs vary dramatically across the United States. A 30-day inpatient program can range from $15,000 in affordable Southern and Midwestern states to $60,000+ in high-cost markets like New York and Massachusetts. Factors driving these differences include regional cost of living, facility density and competition, state Medicaid expansion status, and local insurance market dynamics. States that expanded Medicaid under the ACA generally offer broader access to publicly-funded treatment, while non-expansion states often have higher uninsured rates and greater reliance on private pay or charity care.

Each guide below includes state-specific cost tables, insurance coverage details, free and low-cost treatment options, overdose statistics, and a free cost calculator pre-set for that state.
