The ICD-10 code for Human Granulocytic Anaplasmosis is A77.0. In the ICD-9 coding system, it is represented by the code 082.4. Human Granulocytic Anaplasmosis is a tick-borne infectious disease caused by the bacterium Anaplasma phagocytophilum. It affects the white blood cells and can lead to flu-like symptoms such as fever, headache, and muscle aches. Prompt diagnosis and treatment are crucial for managing this condition.
Human Granulocytic Anaplasmosis (HGA), also known as Anaplasma phagocytophilum infection, is a tick-borne bacterial infection that affects white blood cells (granulocytes), leading to flu-like symptoms, fever, headache, muscle aches, and fatigue. In terms of medical coding, HGA is classified under the International Classification of Diseases, 10th Revision (ICD-10).
The specific ICD-10 code for Human Granulocytic Anaplasmosis is A77.81. This code falls under the category of "Other specified rickettsioses," which includes various bacterial infections caused by Rickettsia and other related organisms. It is important to note that Anaplasma phagocytophilum is an obligate intracellular bacterium, not a rickettsia, but it is grouped under this category due to similarities in clinical presentation and transmission via ticks.
In contrast, the corresponding ICD-9 code for Human Granulocytic Anaplasmosis is 082.4. In the ICD-9 system, this code is classified under the category of "Other specified rickettsioses and other diseases caused by chlamydiae" and includes similar bacterial infections caused by Rickettsia and related organisms.
The transition from ICD-9 to ICD-10 occurred on October 1, 2015, when the healthcare industry adopted the newer coding system to provide more detailed and accurate representation of diseases and conditions. Therefore, it is important for healthcare professionals to use the appropriate ICD-10 code (A77.81) when diagnosing and documenting cases of Human Granulocytic Anaplasmosis.
In summary, the ICD-10 code for Human Granulocytic Anaplasmosis is A77.81, while the equivalent ICD-9 code is 082.4. These codes assist healthcare providers in accurately documenting and tracking cases of HGA, facilitating effective communication and analysis of disease patterns for research and public health purposes.
