Valid for Submission
A02.9 is a billable diagnosis code used to specify a medical diagnosis of salmonella infection, unspecified. The code A02.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code A02.9 might also be used to specify conditions or terms like infection caused by salmonella co-occurrent with human immunodeficiency virus infection, salmonella food poisoning, salmonella infection or salmonella infection associated with aids.
Unspecified diagnosis codes like A02.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Information for Patients
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.
- Abdominal cramps
- 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 the elderly, 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.
