Health industry groups have been encouraged that their input is being sought in the Senate bill to repeal and replace Obamacare, but some say that they are unhappy about ongoing closed-door meetings and a lack of details about how lawmakers will make changes to the healthcare system.

In May, various groups expressed exasperation when the House passed a repeal bill, the American Health Care Act, that they said largely left them out of the conversation. The bill also faced public disapproval and was passed without a final score from the Congressional Budget Office, which makes projections about uninsured rates and the cost to the federal government.
