If Palmetto GBA is your Home Health & Hospice Medicare Administrative Contractor, you may soon have to deal with National Government Services too. “Palmetto GBA has entered into a subcontracting arrangement with National Government Services (NGS) to provide cost report appeal services effective August 27, 2015,” the MAC says on its website. “The transition of this workload includes new and existing cost report appeals for both Part A and HHH services.” The change came with new email and physical addresses for cost report matters, Palmetto notes.
