In Massachusetts, Medicaid and the Children’s Health Insurance Program (CHIP) are combined into one program called MassHealth. Medicaid is a shared state and federal program to provide health insurance for poor and disabled residents. CHIP is medical coverage source for individuals under age 19 whose parents earn too much income to qualify for Medicaid, but not enough to pay for private coverage. MHA monitors prospective and recently implemented changes to MassHealth, provides information about how specific aspects of the plan affect care providers, and advocates for fair and equitable implementation of the program.
