History Background of ICD-10-CM Diagnosis Code A23.1
The ICD-9-CM system, first introduced in 1979, provided the initial framework for coding diseases and health-related conditions in the United States.
The ICD-9-CM diagnosis code for Brucellosis due to Brucella abortus was 023.1(Brucella abortus).This coding remained consistent from 1979 to 2015.
However, 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. Compared to the old system, ICD-10-CM offered a more complete and clear coding structure.
As a result, the shift from ICD-9-CM to ICD-10-CM improved how we record and understand diseases like Brucellosis due to Brucella abortus.
Moreover, it helped healthcare providers give better care through improved documentation and analysis.
The 2025 edition of ICD-10-CM A23.1 became effective on October 1, 2024.
