The combination of increasing operating costs and uncertain government reimbursement funding continues to place health care providers under financial pressure, and in many cases, financial distress. Given the importance of Medicare/Medicaid funding of claims under provider agreements with the federal government, how courts interpret and apply the interplay between the Bankruptcy Code and Medicare Program Act determines the disposition of hundreds of millions of dollars of claims for reimbursement that support the health care system.
