Clinical documentation improvement or integrity (CDI) are synonyms for the process of reviewing medical record documentation for completeness and accuracy of the medical record. CDI includes a review of medical records by trained specialists for documented diagnoses and other clinical information, and what documentation might be missing. These clinical documentation specialists (CDS) then ask physicians for additional information and diagnoses so the medical record can be correctly coded and accurately reflect the full picture of a patient’s medical condition.
