US SB3300

Amends Title XIX of the Social Security Act to create an optional Medicaid coverage pathway for states to provide medical assistance to uninsured individuals with serious mental illness, serious emotional disturbance, opioid use disorder, or stimulant use disorder (including cocaine or methamphetamine)

Limits eligibility to uninsured individuals with income at or below 100% of the federal poverty line who have been diagnosed with a qualifying condition by a health care provider or state-designated entity such as emergency departments, certified community behavioral health clinics, or state judicial/law enforcement/child welfare agencies

Provides coverage for an initial continuous 1-year period, with states having the option to extend for additional 1-year periods upon redetermination that the individual still qualifies

Requires participating states to ensure enrollees receive a care plan within 60 days developed by a qualified provider (physician, primary care provider, community health center, certified community behavioral health clinic, or similar entity)

Mandates that states report behavioral health quality measures from the Core Set of Adult Health Care Quality Measures for Medicaid for individuals enrolled under this option
