A02.9

What This Code Means

A bacterial infection caused by Salmonella bacteria where the specific type or location of infection has not been identified or documented. This is a general diagnosis used when a patient has confirmed Salmonella but more specific details about the infection are unknown.

Coding Tips

• •Use this code only when the specific site of Salmonella infection (such as gastroenteritis, septicemia, or localized infection) cannot be determined from the medical record; otherwise, assign a more specific A02 code
• •Verify whether the infection is foodborne or from another source, as this may affect treatment and reporting requirements; query the provider if documentation is unclear
