A group of Republican lawmakers is calling on the Obama administration to halt a series of Medicare reforms, arguing that officials are overstepping their authority.

The 179 House lawmakers, led by Reps. Tom Price (R-Ga.), Charles Boustany (R-La.) and Erik Paulsen (R-Minn.), are criticizing Medicare reforms put forward by an organization created by ObamaCare.

The Center for Medicare and Medicaid Innovation (CMMI), tasked with finding ways to save Medicare money and better coordinate medical care, has launched several mandatory initiatives that providers in the designated areas must participate it in.
