It may be a red flag, but more likely, I think it's just the medicare advantage plans. Every year, they request all the chart notes for all their insureds that you have seen in a certain time frame. They go over these notes to see if there is any other "chronic" diagnosis that would make them eligible to receive more money from Medicare for the coverage of these patients. Unfortunately, they all do it at the same time too. Right now, I have three audit requests, all 30 to 40 charts each, requesting notes from January 1, 2014 to present.
