T81.11XA ICD-10-CM Code: Postprocedural cardiogenic shock, initial encounter

T81.11XA is the authoritative medical code for Postprocedural cardiogenic shock, initial encounter. This classification is used in medical billing and clinical recording to specify the clinical criteria for postprocedural cardiogenic shock, initial encounter (ICD-10-CM T81.11XA), ensuring healthcare documentation aligns with current federal coding standards.

Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.

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 791 — PREMATURITY WITH MAJOR PROBLEMS (MDC 15)
  • MS-DRG 793 — FULL TERM NEONATE WITH MAJOR PROBLEMS (MDC 15)
  • MS-DRG 919 — COMPLICATIONS OF TREATMENT WITH MCC (MDC 21)
  • MS-DRG 920 — COMPLICATIONS OF TREATMENT WITH CC (MDC 21)
  • MS-DRG 921 — COMPLICATIONS OF TREATMENT WITHOUT CC/MCC (MDC 21)

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.
