A02.1 is a billable and specific ICD-10-CM code. Accurate coding of A02.1 is essential for ensuring effective patient care and facilitating appropriate reimbursement.
This guide provides detailed insights into its application, official guidelines, and historical background.
ICD-10-CM Code for Salmonella sepsis
The ICD-10-CM Diagnosis code for Salmonella sepsis is A02.1.
Salmonella sepsis is a systemic infection caused by Salmonella bacteria that has entered the bloodstream.
Proper documentation using A02.1 ensures patients receive appropriate care and enables accurate healthcare reimbursement.
Synonyms:
- Salmonella septicemia
- Salmonella bacteremia
- Septicemia due to Salmonella
History Background of ICD-10-CM Diagnosis Code A02.1
The ICD-9-CM system, first introduced in 1979, provided the initial framework for coding diseases and health-related conditions in the United States.
In the ICD-9-CM classification, A02.1 was represented by code 003.1, which referred to Salmonella septicemia. This coding remained consistent from 1979 to 2015.
While the ICD-9-CM system offered a basic approach to disease classification, modern healthcare needs more detail and specificity.
To address this, the ICD-10-CM system was launched in 2015, introducing a more comprehensive and accurate coding structure.
The transition from ICD-9-CM to ICD-10-CM significantly improved the ability to document and analyze conditions of Salmonella septicemia.
The 2025 edition of ICD-10-CM A02.1 became effective on October 1, 2024.
| Year | Code | Description |
| 2020 | A02.1 | No Change |
| 2021 | A02.1 | No Change |
| 2022 | A02.1 | No Change |
| 2023 | A02.1 | No Change |
| 2024 | A02.1 | No Change |
| 2025 | A02.1 | No Change |
Symptoms of Salmonella sepsis:
- Persistent high fever
- Rapid heart rate (tachycardia)
- Chills
- Weakness and fatigue
- Low blood pressure
- Confusion or altered mental status
- Organ dysfunction in severe cases (e.g., kidney or liver)
How Salmonella Sepsis is Caused
Salmonella sepsis occurs when Salmonella bacteria invade the bloodstream.
Common sources include:
- Consuming contaminated food or water
- Direct transmission from infected individuals or animals
Once in the bloodstream, the bacteria trigger a systemic immune response, leading to widespread inflammation and, in severe cases, septic shock.
Other ICD-10-CM Diagnosis Codes in A02
ICD-10-CM code A02 | Other salmonella infections has following sub categories including A02.1 :
- A02 Other salmonella infections
- A02.0 Salmonella enteritis
- A02.1 Salmonella sepsis
- A02.2 Localized salmonella infections
- A02.20 Localized salmonella infection, unspecified
- A02.21 Salmonella meningitis

- A02.24 Salmonella osteomyelitis
- A02.25 Salmonella pyelonephritis
- A02.29 Salmonella with other localized infection
- A02.8 Other specified salmonella infections
- A02.9 Salmonella infection, unspecified
Final Thoughts
Proper coding of A02.1 is crucial for accurately diagnosing and effectively managing Salmonella sepsis. For appropriate documentation, medical professionals must understand its causes, symptoms, and historical context. This code is key in ensuring proper reimbursement and improving patient care outcomes.
