CASPER, Wyo. (AP) — The Eastern Shoshone Tribe in central Wyoming has accused the SageWest Health Care hospital in Fremont County of overcharging tribal members on their medical bills.

The tribe's business council says in a statement that the hospital is charging exorbitant and inappropriate rates.

Matt Silverstein, who provides support to tribes on their health plans, says a tribal audit of its hospital bills found errors in roughly 20 percent of the charges from SageWest.

In a statement, SageWest marketing director Lindsey Anderson says the hospital is confident that it bills tribal patients fairly and is not aware of any billing errors.

SageWest operates hospitals in Lander and Riverton and is owned by Apollo Global Management, a New York-based equity firm.
