The Centers for Medicare & Medicaid Services will host a conference call Tuesday on the State Innovation Models initiative and how health care providers can participate. The initiative last month awarded six states a portion of more than $250 million to test proposals to improve health care delivery and payment for Medicare, Medicaid and Children's Health Insurance Program beneficiaries. Another 19 states received awards to plan and design proposals. For more on the call, from 3-4 p.m. Eastern Time, click here. An audio recording and transcript will be posted after the call.
