部落 MAA 計劃說明​​ 

California福利和機構法典 (W&I) 第14132.47條規定，美洲原住民印第安部落、部落組織和部落小組是Medi-Cal行政活動 (MAA) Program的參與者。 這項修改允許美洲原住民印第安部落、部落組織以及部落或部落組織的子群體（在地方政府機構的定義範圍內）簽訂行政活動合約。California有 107 個聯邦認可的部落和大約 12 個部落組織。 目前，只有聯邦認可的部落和符合條件的部落組織才能申請 MAA 。​​ 

The Tribal MAA program was implemented pursuant to the provisions contained in the Tribal MAA Implementation Plan of 2009. The Tribal MAA Contractor is the only entity that will submit the Tribal MAA Invoice to the Department of Health Care Services (DHCS) and is responsible for the preparation of the Tribal MAA Invoice and all backup and supporting documentation kept in the audit file.  For invoices submitted for costs associated with the Tribal Organization and all subcontractors, the Tribal MAA Contractor will ensure receipt and review of all backup and supporting documentation prior to submission of the invoice to DHCS.​​
