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 306 — CARDIAC CONGENITAL AND VALVULAR DISORDERS WITH MCC (MDC 05)
  • MS-DRG 307 — CARDIAC CONGENITAL AND VALVULAR DISORDERS WITHOUT MCC (MDC 05)

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.
