Excludes1 (never coded together)

MS-DRG grouping when Z01.00 is the principal diagnosis

MS-DRG v44 groups for Z01.00 as principal diagnosis
MDCMS-DRGs
23 MDC 23: Factors Influencing Health Status and Other Contacts with Health Services951

The final group also depends on procedures, secondary diagnoses and discharge status; the MS-DRG lookup for Z01.00 shows the full grouping logic.

CC/MCC status and inpatient edits

Z01.00 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 Z01.00 against a principal diagnosis.

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

CMS-HCC V28 risk adjustment

Z01.00 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.
