A02.2 is a billable and specific ICD-10-CM code. Accurate coding of A02.2 is essential for ensuring effective patient care and facilitating appropriate reimbursement.
This guide provides detailed insights into its application, official guidelines, and historical background.
ICD-10-CM Code for Localized Salmonella Infections
The ICD-10-CM Diagnosis code for Localized Salmonella Infections is A02.2.
Localized Salmonella infections refer to specific infections caused by Salmonella bacteria in organs or tissues outside the bloodstream.
Proper documentation using A02.2 ensures patients receive appropriate care and enables accurate healthcare reimbursement.
History Background of ICD-10-CM Diagnosis Code A02.2
The ICD-9-CM system, first introduced in 1979, provided the initial framework for coding diseases and health-related conditions in the United States.
In the ICD-9-CM classification, A02.2 was represented by 003.20.which referred to localized Salmonella infections in different tissues. This code remained consistent from 1979 to 2015.
Here are some other ICD-9-CM codes for salmonella infections:
| ICD-9-CM | Description |
| 003.0 | Salmonella gastroenteritis |
| 003.1 | Salmonella septicemia |
| 003.8 | Salmonella infections |
| 003.9 | Unspecified infections |
While the ICD-9-CM system offered a basic approach to disease classification, it lacked the detail and specificity required for modern healthcare needs.
To address this, the ICD-10-CM system was launched in 2015, introducing a more comprehensive and accurate coding structure.
The transition from ICD-9-CM to ICD-10-CM significantly improved the ability to document and analyze conditions like localized Salmonella infections, ensuring better alignment with contemporary clinical practices.
The 2025 edition of ICD-10-CM A02.2 became effective on October 1, 2024.
