The CDEO credential validates a documentation professional’s expertise in reviewing outpatient documentation for accuracy in the support of coding, quality measures and clinical requirements. CDEO professionals provide feedback to providers to improve clinical documentation and facilitate ongoing documentation improvement to meet all requirements of the medical record. To become a CDEO, documentation professionals must demonstrate knowledge of pathophysiology, coding and billing guidelines, and quality measures.
