The Center for Medicare and Medicaid Innovation, created under the ACA, will award grants, beginning in March, to doctors, community groups, local governments, and others who propose ways to improve care to beneficiaries of Medicare, Medicaid, and CHIP.  Grants of up to $30 million over three years will be awarded to accelerate hiring health care workers and to test new ways to deliver better, more cost-effective medical services. Administration sources expressed views that these grants would help economic development and provide support for ongoing efforts to provide better health care and lower costs.
