The agency has scheduled four calls thus far, set to take place April 28, May 4, May 5, and May 12. Each call will start at 1:00 pm Eastern and last 90 minutes. "The RAC operational process will be discussed and there will be a question and answer session held at the end," CMS said in its announcement. "These calls offer another opportunity for providers who missed the earlier presentations to hear the RAC 101 session and to ask any questions they may have regarding the RAC process." You need not register for the calls, but to get the dial-in information, visit the CMS Web site at www.cms.gov/RAC/03_RecentUpdates.asp#TopOfPage.
