Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the A02 range.

Salmonella

A genus of gram-negative, facultatively anaerobic, rod-shaped bacteria that utilizes citrate as a sole carbon source. It is pathogenic for humans, causing enteric fevers, gastroenteritis, and bacteremia. Food poisoning is the most common clinical manifestation. Organisms within this genus are separated on the basis of antigenic characteristics, sugar fermentation patterns, and bacteriophage susceptibility.

Salmonella Food Poisoning

Poisoning caused by ingestion of food harboring species of SALMONELLA. Conditions of raising, shipping, slaughtering, and marketing of domestic animals contribute to the spread of this bacterium in the food supply.

Salmonella Infections

Infections with bacteria of the genus SALMONELLA.

Salmonella Infections, Animal

Infections in animals with bacteria of the genus SALMONELLA.

About the A02 Code Range

ICD-10 code A02 encompasses various other salmonella infections beyond typhoid and paratyphoid fever, including intestinal, septic, and localized infections caused by different Salmonella bacteria. These codes identify infections ranging from Salmonella enteritis to more severe systemic and localized conditions.

For example, A02.0 is used for Salmonella enteritis, also known as Salmonella gastroenteritis or intestinal infection caused by Salmonella groups A, C, D, E, or Arizona. When the infection spreads to the bloodstream, A02.1 specifies salmonella sepsis, or bloodstream infection caused by Salmonella bacteria. Localized infections at particular sites are captured under subcodes like A02.21 for salmonella meningitis, A02.22 for salmonella pneumonia, and A02.23 for salmonella arthritis. The unspecified A02.9 covers salmonella infections where the exact location or type isn’t recorded, including food poisoning and infections co-occurring with HIV/AIDS. This thorough ICD-10 code section helps clinicians and coders accurately categorize and report the diverse manifestations of salmonella infections.
