5 weeks of uncertainty: How the Change breach has unfolded

Change Healthcare processes about 50% of medical claims and manages prior authorization requests and reimbursement processes. The unprecedented network outage has forced hospitals, nursing homes, pharmacies and other providers to scramble as they try to mitigate operational and financial challenges.
