On December 16, 2014 Ohio was awarded a $75 million four-year State Innovation Models (SIM) testing grant to implement enhanced primary care and value-based episode payment models in partnership with Ohio's largest commercial health insurers. The state composed a State Health Care Innovation Plan to create a sustainable, patient-centered delivery and payment system over the next three to five years. During this time, the state, along with its Medicaid managed care organizations and a multi-payer coalition (that includes the four private payers who represent 80 percent of the commercial market) will launch two models statewide: a patient-centered medical home (PCMH) model and an episode-based payment model. Ohio also proposes that Medicare support this effort, at least by producing total cost of care reports for providers and ideally by fully adopting the PCMH and episode-based payment models in the testing phase of implementation.
