ICD-10 Code A02.8 – Other specified salmonella infections (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A02.8 – Other specified salmonella infections
What it is
This code identifies a Salmonella infection that does not fit a more specific ICD-10 category. Use it when the record names Salmonella infection but does not specify the exact clinical form.
Clinical signs
Clinical features vary; refer to documentation. Salmonella infections commonly involve gastrointestinal illness, and may include diarrhea, abdominal pain, fever, nausea, or vomiting.
When to use this code
Use A02.8 when the provider documents an “other specified” Salmonella infection and no more precise code is supported. It is appropriate when the organism is identified as Salmonella, but the presentation is not one of the more specific listed conditions. Check documentation if the note suggests a different infectious diagnosis or a carrier state.
Do not use for
Do not use this code for unspecified Salmonella infection when the record does not support a more specific description. Also avoid it if the provider documents a different Salmonella category or a non-Salmonella cause.
Coding tip
Confirm the exact wording in the assessment and microbiology results before assigning A02.8.
