Shares of hospital stocks such as HCA Holdings, (HCA) - Get ReportCommunity Health Systems, (CYH) - Get ReportTenet Healthcare (THC) - Get Report , and others were declining on Tuesday afternoon as House Republicans said they were considering a new effort to repeal and replace Obamacare following last week's failed attempt.

Hospital stocks rallied after it became clear on Friday that Obamacare would be sticking around longer than the new administration would like.

However, despite what Republicans are saying, some don't believe this new attempt will get much traction.

"A full blown push at the repeal and replace is going to be extremely difficult to pull off. I can't see how they achieve that," healthcare lobbyist and attorney with the law firm Polsinelli Julius Hobson told Reuters.
