ICD-10 Code A02.22 – Salmonella pneumonia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A02.22 – Salmonella pneumonia
What it is
A02.22 identifies pneumonia caused by Salmonella infection. Use it when the record clearly documents Salmonella as the cause of the lung infection.
Clinical signs
Clinical features vary; refer to documentation. Typical pneumonia findings may include cough, fever, dyspnea, chest discomfort, and imaging evidence of lung involvement.
When to use this code
Use this code when the provider states Salmonella pneumonia or confirms Salmonella infection involving the lungs. It is appropriate for documented cases where pneumonia is attributed to Salmonella species. If the note only says Salmonella infection without pulmonary involvement, check documentation before assigning this code.
Do not use for
Do not use for uncomplicated Salmonella gastroenteritis, enteritis, or septicemia without pneumonia. Also avoid it when pneumonia is present but Salmonella is not identified as the cause.
Coding tip
Confirm the organism and the site of infection in the provider note before coding A02.22.
