ICD 10 coding tips for Zoonotic Bacterial Diseases

Many ICD 10 codes have been added for Bacterial diseases. There ICD 10 codes are very specific for each bacterial disease. As we know, there are many bacterial diseases like plaque, anthrax  etc.These diseases and infection have a particular specific ICD 10 code. Some of these diseases need an additional code for more specificity. Hence, it is very important to learn about all these bacterial disease and infections which are commonly coded by medical coders. So, let see the list of these ICD 10 codes for bacterial diseases.
