What This Code Means
A02.29 is the ICD-10-CM diagnosis code for salmonella with other localized infection. This code describes a bacterial infection caused by Salmonella bacteria that has spread to a specific part of the body other than the intestines, such as bones, joints, or other organs. It represents a localized infection rather than a widespread systemic infection. A02.29 sits in the ICD-10-CM chapter for certain infectious and parasitic diseases (a00-b99), within the section covering intestinal infectious diseases (a00-a09).
A02.29 is a billable ICD-10-CM code but does not map to a payment HCC under the CMS-HCC V28, V24, ESRD, or RxHCC risk adjustment models. It can be reported on Medicare Advantage encounter data submissions but it does not contribute to a beneficiary's RAF score and therefore does not affect risk-adjusted payments to the plan.
Always specify the site of infection when coding Salmonella with localized infection, as this affects the specificity and accuracy of the diagnosis code.
HCC Buddy maintains structured V28 and V24 mapping, RAF weights, and MEAT documentation criteria for A02.29 sourced directly from the CMS-HCC risk adjustment model files and the CMS ICD-10-CM code set.
Coding Tips
- •Always specify the site of infection when coding Salmonella with localized infection, as this affects the specificity and accuracy of the diagnosis code
- •Verify that the infection is localized to one area rather than generalized or septicemic, as this distinction determines whether A02.29 or a different A02 code should be used
