The final group also depends on procedures, secondary diagnoses and discharge status; the MS-DRG lookup for I69.819 shows the full grouping logic.

CC/MCC status and inpatient edits

I69.819 is neither a CC nor an MCC under MS-DRG v44, so as a secondary diagnosis it does not raise the MS-DRG severity level. Check I69.819 against a principal diagnosis.

  • Present on admission: exempt from POA indicator reporting (FY2027 exempt list).

CMS-HCC V28 risk adjustment

I69.819 does not map to a payment HCC in the PY2027 CMS-HCC V28 model, so on its own it does not change a Medicare Advantage risk score.
