ICD-10/K91.840

K91.840 ICD-10-CM Code: Postprocedural hemorrhage of a digestive system organ or structure following a digestive system procedure

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, Appendix B.

  • 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.

Potential MS-DRG Relationships (FY2026)

CC — Complication or Comorbidity. Reported as a secondary diagnosis, this code raises the stay's MS-DRG severity tier — except when the principal diagnosis is one of 76 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 3 MS-DRGs: DRG 919 (MDC 21), DRG 920 (MDC 21), DRG 921 (MDC 21).

From the CMS MS-DRG Definitions Manual (Appendices B and C). Actual DRG assignment depends on the complete claim.
