Of 200 claims sampled in the August 31, 2009, CERT Feedback Report, 136 errors were identified. Nearly half of errors identified in the August 31, 2009, CERT Feedback were a result of a lack of documentation of medical necessity. In addition, more than 36 percent of errors identified were a result of insufficient documentation. Of that 36 percent, approximately two-thirds of the insufficient documentation errors were due to failure to meet signature requirements.
