CDIP Domain 3: Research & Education Practice Test

DRGs assign the hospital stay based on the specific cerebrovascular diagnosis, whether there is brain infarction, and whether major complications or comorbidities are present. When you have a nonspecific cerebrovascular event plus precerebral occlusion but no infarction, and there are no major complications or comorbidities, this falls into the lowest-severity cerebrovascular DRG in that family. That combination is mapped to the DRG number corresponding to cerebrovascular disorders without infarction and without MCC, which is DRG 68. If infarction were present or if there were a major complication or comorbidity, a higher-numbered DRG would apply to reflect increased resource use.
