ICD-10/K85.92

K85.92 ICD-10-CM Code: Acute pancreatitis with infected necrosis, unspecified

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 438 — DISORDERS OF PANCREAS EXCEPT MALIGNANCY WITH MCC (MDC 07)
  • MS-DRG 439 — DISORDERS OF PANCREAS EXCEPT MALIGNANCY WITH CC (MDC 07)
  • MS-DRG 440 — DISORDERS OF PANCREAS EXCEPT MALIGNANCY WITHOUT CC/MCC (MDC 07)
  • MS-DRG 791 — PREMATURITY WITH MAJOR PROBLEMS (MDC 15)
  • MS-DRG 793 — FULL TERM NEONATE WITH MAJOR PROBLEMS (MDC 15)

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)

MCC — Major 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 24 clinically related codes on its CMS exclusion list.

Named in the grouper logic of 5 MS-DRGs: DRG 438 (MDC 07), DRG 439 (MDC 07), DRG 440 (MDC 07), DRG 791 (MDC 15), DRG 793 (MDC 15).

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