Tabular list notes for M95.0

The tabular list has no notes on M95.0 itself; the notes below apply from its parent headings.

Inherited from M95 (Other acquired deformities of musculoskeletal system and connective tissue)

Excludes2 (not part of this condition, may be coded together)
  • acquired absence of limbs and organs (Z89-Z90)
  • acquired deformities of limbs (M20-M21)
  • congenital malformations and deformations of the musculoskeletal system (Q65-Q79)
  • deforming dorsopathies (M40-M43)
  • dentofacial anomalies [including malocclusion] (M26.-)
  • postprocedural musculoskeletal disorders (M96.-)

MS-DRG grouping when M95.0 is the principal diagnosis

MS-DRG v44 groups for M95.0 as principal diagnosis
MDCMS-DRGs

The final group also depends on procedures, secondary diagnoses and discharge status; the MS-DRG lookup for M95.0 shows the full grouping logic.

CC/MCC status and inpatient edits

M95.0 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 M95.0 against a principal diagnosis.

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

CMS-HCC V28 risk adjustment

M95.0 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.
