ICD-10 Code A02.1 – Salmonella sepsis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A02.1 – Salmonella sepsis
What it is
A02.1 identifies sepsis caused by Salmonella infection. Use it when the record shows Salmonella as the source of bloodstream infection and systemic illness.
Clinical signs
Typical findings include fever, chills, hypotension, and other signs of systemic infection. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents Salmonella sepsis, septicemia due to Salmonella, or bloodstream infection from Salmonella. You should code it only when the organism and sepsis are clearly linked in the chart. Check documentation if the record mentions Salmonella infection without sepsis.
Do not use for
Do not use A02.1 for uncomplicated Salmonella gastroenteritis or enteritis without sepsis. Do not assign it when Salmonella is only suspected or not confirmed in the documentation.
Coding tip
Confirm that the note explicitly connects sepsis to Salmonella before coding A02.1.
