MS-DRG grouping when F32.A is the principal diagnosis

MS-DRG v44 groups for F32.A as principal diagnosis
MDCMS-DRGs
19 MDC 19: Mental Diseases and Disorders881

The final group also depends on procedures, secondary diagnoses and discharge status; the MS-DRG lookup for F32.A shows the full grouping logic.

CC/MCC status and inpatient edits

F32.A 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 F32.A against a principal diagnosis.

  • Present on admission: a POA indicator is required on inpatient claims.

CMS-HCC V28 risk adjustment

F32.A 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.

For teams evaluating QuickIntell software

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.
