Coding at a Glance

Tabular directives
1 inclusion term

Inpatient Payment Groups (MS-DRG)

Potential MS-DRG participation — not a DRG assignment.

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

  • MS-DRG 371 — MAJOR GASTROINTESTINAL DISORDERS AND PERITONEAL INFECTIONS WITH MCC (MDC 06)
  • MS-DRG 372 — MAJOR GASTROINTESTINAL DISORDERS AND PERITONEAL INFECTIONS WITH CC (MDC 06)
  • MS-DRG 373 — MAJOR GASTROINTESTINAL DISORDERS AND PERITONEAL INFECTIONS WITHOUT CC/MCC (MDC 06)

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.

Relationships & Classification

MedCoder structured relationships — computed from published CMS and AHRQ datasets

Other codes that name A07.0 or its code family, from the CMS ICD-10-CM tabular instructional notes. Tabular-note edges are stored at the code family level that carries each note.

Referenced by 14 Excludes1 notes: A06 — Amebiasis (via A07.-), B50 — Plasmodium falciparum malaria (via A07.-), B50-B64 — Protozoal diseases (B50-B64) (via A07.-), B51 — Plasmodium vivax malaria (via A07.-), B52 — Plasmodium malariae malaria (via A07.-), B53 — Other specified malaria (via A07.-), B54 — Unspecified malaria (via A07.-), B55 — Leishmaniasis (via A07.-), B56 — African trypanosomiasis (via A07.-), B57 — Chagas' disease (via A07.-), B58 — Toxoplasmosis (via A07.-), B59 — Pneumocystosis (via A07.-), B60 — Other protozoal diseases, not elsewhere classified (via A07.-), B64 — Unspecified protozoal disease (via A07.-).

These codes’ tabular lists mark this diagnosis as mutually exclusive — not reported together unless the conditions are documented as unrelated.

Referenced by 6 Excludes2 notes: P35 — Congenital viral diseases (via A07.-), P35-P39 — Infections specific to the perinatal period (P35-P39) (via A07.-), P36 — Bacterial sepsis of newborn (via A07.-), P37 — Other congenital infectious and parasitic diseases (via A07.-), P38 — Omphalitis of newborn (via A07.-), P39 — Other infections specific to the perinatal period (via A07.-).

These codes’ tabular lists name this diagnosis as distinct — both may be reported when both are documented.

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

FY2026 MS-DRG: not on the CMS CC/MCC list — as a secondary diagnosis this code does not change MS-DRG severity for that release.

Named in the grouper logic of 3 MS-DRGs: DRG 371 (MDC 06), DRG 372 (MDC 06), DRG 373 (MDC 06).

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