On Tuesday, President-elect Donald J. Trump announced his nomination of six-term Republican Congress member Tom Price of Georgia to be the Secretary of Health and Human Services.

Like many of his Republican colleagues, Price has been a vocal and long-standing critic of the Affordable Care Act, aka Obamacare. But Price, a former orthopedic surgeon, stands apart. While other Republicans have expressed their desire take a hatchet to the landmark healthcare law, he has taken up a scalpel and carved out the most detailed plan yet to repeal and replace the ACA.

‘Repeal and replace’ was a mantra of Trump’s campaign, yet the President-elect provided no specifics on how to do it or what might replace the ACA. Price’s plan could fill that void. But uncertainty still prevails over any prognosis for the country’s healthcare system. Up for speculation is everything from the political maneuvers necessary to repeal the ACA to the Republican establishment’s acceptance of Price’s replacement plan, some aspects of which are at odds with other Republican plans.
