The expansion of Medicaid under the Affordable Care Act in Michigan has so far been a very big success — and a politically bipartisan one signed into law by GOP Gov. Rick Snyder. Here’s why, as explained in a HealthAffairs piece.

Consider, among the signs of success:

“Operational issues with enrollment have been minimal and health plan participation has been high, with thirteen health plans serving the Healthy Michigan Plan {the name of the state Medicaid program} population in the first year. Moreover, the proportion of primary care practices willing to accept new Medicaid patients in Michigan has increased from 49 percent to 55 percent since the launch of the Healthy Michigan Plan — with median wait times for new appointments remaining less than two weeks.’
