Extending Access to Addiction Treatment Act

This bill makes permanent a requirement that all states cover medication-assisted treatment (MAT) for opioid use disorder in their Medicaid programs. It removes an expiration date (previously set for September 30, 2025), ensuring continuous coverage without a sunset clause. States must now certify compliance with this requirement at least every five years, rather than annually before a deadline. The policy directly affects all 50 states and the District of Columbia that administer Medicaid, maintaining existing access to MAT without new funding or program changes.
