There is separate ICD 10 coding guideline for coding sepsis, severe sepsis and Septic shock. We have to code multiple or more than one ICD 10 code for coding sepsis. Many coders make lot of mistakes in coding Sepsis. Hence, it is very important to know about the ICD 10 codes for coding sepsis. So, I am going to share the list of ICD 10 codes for coding sepsis. Do remember to read the ICD 10 coding guideline first before coding sepsis codes.
