The final group also depends on procedures, secondary diagnoses and discharge status; the MS-DRG lookup for Z87.19 shows the full grouping logic.

CC/MCC status and inpatient edits

Z87.19 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 Z87.19 against a principal diagnosis.

  • Present on admission: exempt from POA indicator reporting (FY2027 exempt list).
  • Medicare Code Editor: unacceptable principal diagnosis.

CMS-HCC V28 risk adjustment

Z87.19 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.

Evaluate software for diagnosis coding review

If your team codes diagnoses at volume, review how QuickCode supports qualified coder review of documentation, specificity queries and the billing handoff. Confirm the code sets, settings and reviewer responsibilities during evaluation; a code reference is not a coding determination for a patient.
