(Olympia, WA)  --  The Washington State Health Authority says it's dealing with a data breach of personal information belonging to tens of thousands of Apple Health Medicaid clients.  Officials say two employees at different agencies exchanged files that included Social Security numbers, dates of birth, Apple Health client ID numbers and private health information on about 91-thousand clients, in violation of federal regulations.  The Health Authority says while there's no indication that the client files went beyond the two individuals involved, exercise and diligence are being exercised to keep the data contained.
