WINNEBAGO, Neb. (AP) — The Winnebago Indian Health Services Hospital in northeast Nebraska is set to lose Medicare funding within a week.

The U.S. Centers for Medicare & Medicaid Services says the hospital’s Medicare agreement will be terminated June 4. That means the hospital would no longer be reimbursed for treating patients enrolled in the health care program for the elderly and disabled.

An agency notice says the hospital is not in compliance with Medicare regulations. John Blackhawk, chairman of the Winnebago Tribe, says the hospital is working with the federal agency to avert the cutoff.

The hospital was warned earlier this month that it could lose its Medicare funding after an investigation found inadequate care contributed to the April death of a patient.
