Dual Eligible Project (MMP)

Effective January 1, 2022, Cigna will no longer participate in the Medicare-Medicaid Dual Eligibles Project and will transfer its Texas Medicaid business to Molina Healthcare. The following links have more information about this transition for providers and members:

HHSC will make further updates to this website to reflect this change.

The Texas Health and Human Services Commission offers a way to serve adults who are eligible for both Medicare and Medicaid, known as dual-eligible members. The goal of the project is to better coordinate the care those dual-eligible members receive.

The project, also known as "the demonstration," tests an innovative payment and service delivery model to improve coordination of services for dual-eligible members, enhance quality of care, and reduce costs for both the state and the federal government. By having one Medicare-Medicaid health plan, Medicare and Medicaid benefits work together to better meet the member’s health-care needs.

Beginning April 1, 2015, dual-eligible members in the six demonstration counties were passively enrolled into a Medicare-Medicaid plan, following a notification process, explained below. The notification process involves letters sent to members to explain the project and identify the Medicare-Medicaid plan the member was enrolled in if the member takes no action. The Medicare-Medicaid plan provides the full array of Medicaid and Medicare services, integrating acute care and long-term services and supports.


  1. Make it easier for clients to get care.
  2. Promote independence in the community.
  3. Eliminate cost shifting between Medicare and Medicaid.
  4. Achieve cost savings for the state and federal government through improvements in care and coordination.
