My Medicare or Medi-Cal is through an HMO program. Why do I need to provide my Medicare number (MBI) or AHCCCS number?

Medicare and Medi-Cal have provided guidance that the vaccine administration should be billed directly to the government program instead of the HMO to simplify the administration and tracking. We require the correct member ID number to properly bill/report to the government program. There’s no out-of-pocket cost to you to get the COVID-19 vaccine.
