Which MS-DRGs does I61.0 group to?

I61.0 sits in MDC 01 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

020Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage with MCCsurgical
021Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage with CCsurgical
022Intracranial Vascular Procedures with Principal Diagnosis Hemorrhage without CC/MCCsurgical

As a secondary diagnosis, I61.0 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.

Report an additional code alongside I61.0 to fully describe the condition. I61.0 is sequenced first.
