There are several components of CDI performed by clinical documentation specialists (CDS) including the following: - Selection of medical records to be reviewed. - Review of medical records to identify a working principal diagnosis, significant procedures, and pertinent comorbid diagnoses to establish a working DRG. - Identification of additional diagnoses and procedures that may not yet have been properly documented for correct coding and that may affect the final DRG. - Submitting clarification questions (“queries”) to clinicians caring for a patient to obtain additional needed documentation. - Follow-up of unanswered, when necessary - Verification that all pertinent diagnoses affecting the DRG are supporting by clinical findings in the medical record. - Collaborate with coding colleagues to ensure that the final CDS DRG matches the finalize coder DRG for claim submission. - Keeping succinct notes of all findings and actions.
