While the ICD-9-CM system offered a basic approach to disease classification, modern healthcare needs more detail and specificity.
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 such as Brucellosis due to Brucella canis.
The 2025 edition of ICD-10-CM A23.3 became effective on October 1, 2024.
