ICD-10 Code A02.2: Localized salmonella infections

A02.2 is an ICD-10 diagnosis entry used to group records related to Localized salmonella infections. You may see this entry in coding references, medical records, or claims workflows when a broader diagnosis category is being reviewed before a more specific code is chosen. ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Certain infectious and parasitic diseases (A00-B99).

What is this code?

ICD-10 entries help standardize how diagnoses are organized for coding, reporting, analytics, and documentation. This code sits within the broader ICD-10 area for Certain infectious and parasitic diseases (A00-B99).

đź“‹Clinical overview

This ICD-10 code is commonly used when documentation describes a salmonella infection. The most accurate code depends on whether the chart identifies intestinal disease, sepsis, a named localized extraintestinal infection such as meningitis or osteomyelitis, another specified salmonella presentation, or an unspecified salmonella infection.

When is it used?

  • May be used when a clinician documents localized salmonella infections in a patient's medical record.
  • May appear in hospital records, claims, referrals, and clinical documentation.
  • This code may act more like a grouping or parent code, so a more specific child code may be used in final documentation when available.

What it does not mean

  • A code alone does not explain severity, treatment plan, or outcome.
  • A medical code should not be treated as a substitute for a doctor's diagnosis or advice.
  • This entry may represent a broader category rather than the most specific billable code.

đź©şClinical context

When commonly used
  • Primary-care, urgent-care, emergency, gastroenterology, infectious-disease, inpatient, and follow-up documentation where salmonella is part of the active assessment after stool testing, blood cultures, or site-specific infection workup.
  • Coding and utilization-review workflows where the chart distinguishes salmonella enteritis from sepsis or from a localized organ infection and that distinction changes final code specificity.
Common management context
  • Evaluation often includes symptom review for diarrhea, fever, abdominal pain, dehydration, or focal-organ symptoms; stool or blood-culture review; fluid-status assessment; and antimicrobial planning when severe or invasive disease is documented.
  • Documentation usually becomes more specific when the chart identifies intestinal versus bloodstream versus localized extraintestinal disease, or names the exact localized site such as meningitis, pneumonia, arthritis, osteomyelitis, or pyelonephritis.
  • Specialist context already linked on this page includes Infectious Disease Specialist, General Physician.

🔍Key distinctions

Important notes
  • This ICD-10 family captures salmonella infections across intestinal and invasive disease patterns, and it is distinct from other bacterial intestinal infection families because the organism is named directly.
  • Site-of-infection detail matters strongly here, especially when salmonella extends beyond enteritis into sepsis or a named localized extraintestinal infection.
  • This parent page groups localized salmonella infections outside the usual intestinal presentation, so the final billable code usually depends on whether the chart identifies meningitis, pneumonia, arthritis, osteomyelitis, pyelonephritis, another localized site, or leaves the localized infection unspecified.
  • Documentation that describes salmonella infection is coded differently from other bacterial intestinal infections, viral gastroenteritis, or noninfectious inflammatory bowel conditions because the organism and affected site drive final code selection.
