WASHINGTON (Reuters) - U.S. Senate Republicans on Monday released changes to their healthcare bill, including a six-month waiting period for people who have let their insurance coverage lapse for over 63 days - about two months - and want to get insured again. The change appeared aimed at deterring people from dropping health insurance to begin with, a concern that arose in part because the bill cancels the monetary penalty for being uninsured under the current law, known commonly as Obamacare. Senate leaders want to hold a vote on the bill before the July 4 recess that starts at the end of this week.
