Inpatient Payment Groups (MS-DRG)

MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0 (FY2026), Appendix B.

  • MS-DRG 582 — MASTECTOMY FOR MALIGNANCY WITH CC/MCC (MDC 09)
  • MS-DRG 583 — MASTECTOMY FOR MALIGNANCY WITHOUT CC/MCC (MDC 09)
  • MS-DRG 597 — MALIGNANT BREAST DISORDERS WITH MCC (MDC 09)
  • MS-DRG 598 — MALIGNANT BREAST DISORDERS WITH CC (MDC 09)
  • MS-DRG 599 — MALIGNANT BREAST DISORDERS WITHOUT CC/MCC (MDC 09)

A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.

Code Set: Valid FY2026 and FY2027. FY2026 took effect October 1, 2025.
