Abstract: A computer system implements a concurrent Clinical Document Improvement (CDI) and coding workflow, such as may be used to generate codesets for use in connection with medical bills. The concurrent workflow enables steps in the coding process to be performed close to admission and concurrently with (e.g., interwoven with) the patient visit and steps in the CDI process, thereby increasing the accuracy of the resulting codesets and the efficiency of the codeset generation process. In particular, this concurrent coding workflow may be used to resolve DRG mismatches and enable codesets to be finalized immediately upon discharge of the patient from the hospital.
