Colorado’s Senate has tentatively endorsed legislation requiring hospitals to disclose many of their expenditures to help lower health care costs.

The Senate voted Wednesday. Another vote will send the bill to the House, which has approved it, to consider Senate amendments.

Sponsors include Democratic Rep. Chris Kennedy and Sen. Dominick Moreno and Republican Sen. Bob Rankin.

It would require hospitals to provide financial reports to the state, which would compile annual reports on uncompensated care costs.

Kennedy says hospital care accounts for nearly 40 percent of total health care costs in Colorado.

He argues the legislation would, in part, allow policymakers to better understand why rural health insurance premiums, which reflect cost, are some of the highest in the nation.
