Small private practices and health-care providers are facing mounting financial pressures as crucial reimbursement systems remain down for the ninth day, following the cyberattack on Change Healthcare. Change Healthcare offers tools for payment and revenue cycle management that help facilitate transactions between providers and most major insurance companies. As of Thursday, Change Healthcare has not shared any updates about when it expects its systems to be back online. Change Healthcare on Thursday said that ransomware group Blackcat is behind the attack. He said it's not clear whether Change Healthcare will take on the responsibility of processing all the claims or if he'll need to hire additional staff to help.
