By The Associated Press

Change Healthcare is starting to notify hospitals, insurers and other customers that they may have had patient information exposed in a massive cyberattack. The company also said Thursday that it expects to begin notifying individuals or patients in late July. Change Healthcare is a subsidiary of health care giant UnitedHealth Group. It provides technology used to submit and process billions of insurance claims a year. Hackers gained access in February to its system and unleashed a ransomware attack that encrypted and froze large parts of it.
