A02.20Localized salmonella infection, unspecified

A02.20 is the ICD-10-CM diagnosis code for localized salmonella infection, unspecified. It belongs to category A02 (other salmonella infections), block A00-A09 (intestinal infectious diseases) and chapter 1 (certain infectious and parasitic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within A02.2, choose A02.20 (Localized salmonella infection, unspecified) only when documentation doesn't support a more specific option: salmonella meningitis (A02.21), salmonella pneumonia (A02.22), salmonella arthritis (A02.23), salmonella osteomyelitis (A02.24), salmonella pyelonephritis (A02.25) and salmonella with other localized infection (A02.29).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 867 (Other Infectious and Parasitic Diseases Diagnoses with MCC, relative weight 2.1859), DRG 868 (Other Infectious and Parasitic Diseases Diagnoses with CC, relative weight 1.0235), DRG 869 (Other Infectious and Parasitic Diseases Diagnoses without CC/MCC, relative weight 0.6787), DRG 974 (HIV with Major Related Condition with MCC, relative weight 3.0506), DRG 975 (HIV with Major Related Condition with CC, relative weight 1.3252) and DRG 976 (HIV with Major Related Condition without CC/MCC, relative weight 0.8124), in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites) and MDC 25 (Human Immunodeficiency Virus Infections), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 003.20 (localized salmonella infection, unspecified).
