ICD-10 Code A02.20 – Localized salmonella infection, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code A02.20 – Localized salmonella infection, unspecified
What it is
This code identifies a localized Salmonella infection when the site is not further specified. Use it when documentation confirms Salmonella infection, but the record does not name a particular organ or body system.
Clinical signs
Clinical features vary; refer to documentation. Localized infection may present with focal pain, inflammation, or organ-specific symptoms, but you should code only what is clearly documented as Salmonella-related.
When to use this code
Use A02.20 when the provider documents a localized Salmonella infection and does not identify the exact site. It is appropriate when the chart supports Salmonella as the cause, but the anatomic location remains unspecified. If the record names a specific site, code that more precise diagnosis instead.
Do not use for
Do not use this code for simple Salmonella gastroenteritis or for systemic Salmonella infection without localization. If the documentation identifies a specific organ, check documentation for a more exact code.
Coding tip
Query the provider when Salmonella is documented but the site is unclear, because A02.20 is only for localized infection without a named location.
