Change Healthcare says it handles one in every three patient records in the US. Change Healthcare restored its electronic payments platform on March 15 and “is proceeding with payer implementations,” UnitedHealthGroup said in a statement on Monday. “Billions of dollars” stopped flowing to health care providers because of the hack, according to AHA, which represents thousands of hospitals across the country. The unprecedented pressure on a hacked US health care firm won’t go away with the restoration of billing services. HHS has opened an investigation into whether Change Healthcare has complied with federal law to protect patient data.
