ICD-10 Code A02.1: Salmonella sepsis
Reviewed by HealthAssure Clinical TeamUpdated 26 May 2026
What is this code?
ICD-10 codes are diagnosis classification codes used in healthcare records, reporting, coding workflows, and billing support. 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 salmonella sepsis in a patient's medical record.
- May appear in hospital records, claims, referrals, and clinical documentation.
- This code can be used as a clinically usable diagnosis entry in standardized coding workflows.
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.
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.
- Salmonella sepsis is coded separately from salmonella enteritis and from localized salmonella infection branches because bloodstream infection materially changes code specificity and clinical context.
- 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.
