American Society of Hematology

Carrier Advisory Committee Networking Meeting

Each year, ASH and the American Society of Clinical Oncology (ASCO) co-host the Carrier Advisory Committee (CAC) Network Meeting, which includes invited individuals from the following groups:

  • ASH Committee on Practice
  • ASH Reimbursement Subcommittee
  • ASCO Clinical Practice Committee
  • Medicare Contractor Medical Directors
  • Hematology CAC Representatives
  • Oncology CAC Representatives
  • State Society Presidents
  • State Society Executive Directors

Carrier Advisory Committees

Each state must have at least one Carrier Advisory Committee, which is established by a Medicare Administrative Contractor (MAC). MACs are private health insurers contracted with the Centers for Medicare and Medicaid Services (CMS) to process Medicare claims for a specific geographic region. There are currently 13 MAC regions.

CAC members include physicians (limited to one per specialty or provider type), a beneficiary representative, and representatives of other medical organizations. CACs serve as a mechanism for physicians to be made aware of and participate in the development of new Local Coverage Determinations (LCD), to discuss and amend administrative policies, and to serve as a link between Medicare and the local provider community.

If you are interested in becoming a CAC representative of your state, please reach out to your state society or email Katherine Stark at

ASH-ASCO CAC Network Meeting

ASH and ASCO co-sponsor the CAC Network Meeting as an opportunity for CAC representatives to meet, network, and strengthen relationships. The meeting allows participants to discuss Medicare-related coverage and policy issues (e.g., LCDs), draft policies, and the relationship between Medicare and the provider community. This diverse group of stakeholders also has an opportunity to discuss possible solutions to real-world issues.

The 2019 ASH-ASCO CAC Network Meeting was held at ASCO Headquarters in Alexandria, VA, on June 27-27, 2019. The 2020 ASH-ASCO CAC Network Meeting will be held at ASH Headquarters in Washington, DC.
