Searchable state-by-state Medicaid 340B requirements
This resource has been created by the 340B Prime Vendor Program to assist stakeholders by combining the most recently available 340B-specific Medicaid data with publicly available federal data. Please note that additional requirements or contractual obligations that may be in place from third-party payers are not included in this resource.
Upon selecting a state in the drop-down menu, the Medicaid State Technical, Rebate and Policy contacts and details on the state’s retail prescriptions, provider- or facility-administered drugs, contract pharmacies and Medicaid Managed Care profiles will populate below. Each field is linked to the sourced data where additional information can be found.
Please note: The data presented on this page are compiled from various sources; however, the information is not endorsed by HRSA and not dispositive with the 340B Drug Pricing Program. 340B stakeholders are ultimately responsible for 340B Program compliance and compliance with all applicable state and federal laws and regulations. Stakeholders are encouraged to contact the states to verify current policy/requirements.
