Politico reports that US House members sent a letter to CMMI asking them to stop mandatory work. The innovation center should impose the limits on its experimental models and only gradually expand them following dialogue with participants, according to the letter, which was crafted by Reps. Tom Price, Charles Boustany and Erik Paulsen.

Medicare is forcing new models without consulting with the doctors, hospitals and patients who must participate in them, the lawmakers say. Medicare’s knee- and hip-replacement bundle model, Part B drug payment plan and its forthcoming cardiac bundled-care model are all examples of forcing doctors to participate without consent.

“As a result, Medicare providers and their patients are blindly being forced into high-risk government-dictated reforms with unknown impacts,” the letter states.
