Fulton County, GA, needs to increase payments to Grady Memorial Hospital by nearly half, by about $36 million a year, if the county is going to meet its obligations in covering the hospital's losses on indigent Fulton residents, according to Grady officials. Grady representatives delivered that message in a series of documents, numbers and files presented to county officials as the two sides spar over how much taxpayers should contribute for indigent care. Fulton officials vowed to pore over the files and see if they can verify the numbers.
