Amends TCA Title 33; Title 56; Title 63; Title 68 and Title 71.

Tennessee HB0638 prohibits healthcare providers participating in medical assistance health benefit plans from refusing to provide services to enrollees based solely on their refusal or failure to obtain vaccines or immunizations, with certain exemptions for oncology and organ transplant specialists. The bill mandates that the TennCare director adopt rules for implementation, including a process for reporting violations and the right to administrative review for providers accused of non-compliance. Key provisions include the stipulation that reimbursement will not be provided to non-compliant providers, and the potential for the director to seek federal waivers to enforce the bill.
