Which DRG corresponds to nonspecific CVA and precerebral occlusion without infarction with MCC?

• A. DRG 65
• B. DRG 66
• C. DRG 67
• D. DRG 68

Answer: (C)

In MS-DRG grouping, cerebrovascular disorders are divided not only by the specific brain event (infarction vs. no infarction) but also by the level of severity indicated by major complications or comorbidities (MCC) or complications (CC). When the record shows a nonspecific CVA or precerebral occlusion without infarction and there is a major complication or comorbidity, the case is assigned to the DRG that represents cerebrovascular disorders with MCC. This DRG reflects the higher resource use associated with having an MCC, even though there is no infarction. If infarction were present, or if there were only a CC (or none), a different DRG would apply. Thus, the option that corresponds to MCC in the non-infarction cerebrovascular group is the correct choice.
