The Department of Health may implement a reimbursement system to recover part or all of the costs of delivering services. For the purpose of vaccine and vaccine administration reimbursement, if a private healthcare insurer declines or does not respond to a request to contract with the department within ninety (90) days of the request to contract, the private healthcare insurer shall reimburse the department at the rate paid to an in-network provider. The system shall provide that fees shall be collected only from those patients who are financially able to pay the fee and that no one shall be denied services because of inability to pay. Funds derived from the fees shall be used exclusively for the purchase of medical supplies or services necessary to enable the department to continue to provide essential health care.
