President Donald Trump’s administration made explicit this weekend its commitment to an old GOP strategy for managing Medicaid, the federal-state insurance plan that covers low-income people — turning control of the program to states and capping what the federal government spends on it each year.

It’s called “block granting.” Right now, Medicaid, which was expanded under the 2010 health law to insure more people, covers almost 75 million adults and children. Because it is an entitlement, everyone who qualifies is guaranteed coverage and states and the federal government combine funds to cover the costs. Conservatives have long argued the program would be more efficient if states got a lump sum from the federal government and then managed the program as they saw fit. But others say that would mean less funding for the program —eventually translating into greater challenges in getting care for low-income people.

Block granting Medicaid is a centerpiece of health proposals supported by House Speaker Paul Ryan and Rep. Tom Price, Trump’s nominee to run the Department of Health and Human Services. This weekend, Trump adviser Kellyanne Conway emphasized the strategy as key to the administration’s health policy.

But what would this look like, and why is it so controversial? Let’s break down how this policy could play out, and its implications — both for government spending and for accessing care.
