Non-specific codes like A02 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for other salmonella infections:

  • Use A02.0 for Salmonella enteritis - BILLABLE CODE

  • Use A02.1 for Salmonella sepsis - BILLABLE CODE

  • A02.2 for Localized salmonella infections - NON-BILLABLE CODE

  • Use A02.20 for Localized salmonella infection, unspecified - BILLABLE CODE

  • Use A02.21 for Salmonella meningitis - BILLABLE CODE

  • Use A02.22 for Salmonella pneumonia - BILLABLE CODE

  • Use A02.23 for Salmonella arthritis - BILLABLE CODE

  • Use A02.24 for Salmonella osteomyelitis - BILLABLE CODE

Patient Education


Salmonella Infections

Salmonella is the name of a group of bacteria. In the United States, it is a common cause of foodborne illness. Salmonella occurs in raw poultry, eggs, beef, and sometimes on unwashed fruit and vegetables. You also can get infected after handling pets, especially reptiles like snakes, turtles, and lizards.

Symptoms include:

  • Fever
  • Diarrhea
  • Abdominal cramps
  • Headache
  • Possible nausea, vomiting, and loss of appetite

Symptoms usually last 4-7 days. Your health care provider diagnoses the infection with a stool test. Most people get better without treatment. Infection can be more serious in older adults, infants, and people with chronic health problems. If Salmonella gets into the bloodstream, it can be serious. The usual treatment is antibiotics.

Typhoid fever, a more serious disease caused by Salmonella, is not common in the United States. It frequently occurs in developing countries.
