Why do some risk adjustment coding jobs ask for Microsoft Office Experience and some do not? Is there a big pay difference between these jobs? I am getting back into risk adjustment after 8 years of doing other stuff. Have 6 years of ICD-9 HCC coding, a BSN, and a active RN license. Just did the CRC course and hope to pass test in a month. Is it worth it for a Mac user to try and learn Microsoft Office? In my previous job, they shipped me a computer, which only needed the most basic computer skill set. Thanks, Amy
