Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology.
The coding of severe sepsis requires a minimum of two codes: first a code for the underlying systemic infection, followed by a code from subcategory R65. 2, Severe sepsis. If the causal organism is not documented, assign code A41. 9, Sepsis, unspecified organism, for the infection.
ICD-10 code A41. 89 for Other specified sepsis is a medical classification as listed by WHO under the range - Certain infectious and parasitic diseases .
9: Sepsis, unspecified.

According to the guidelines above, sepsis would be the appropriate principal diagnosis if it is the reason the patient is admitted, and meets the definition of principal diagnosis.
Severe sepsis – Code first the underlying systemic infection, such as 038.0 (Streptococcal septicemia), then code 995.92 for severe sepsis, and finally code the specific type of organ failure, such as 584.9 for acute renal failure.
For cases of septic shock, a minimum of two codes is needed to report severe sepsis with septic shock. Chapter-specific guidelines state, “First code for the underlying systemic infection, followed by R65. 21, septic shock. If the causal organism is not documented, assign code A41.
For septic shock, the code for the underlying infection should be sequenced first, followed by code R65. 21, Severe sepsis with septic shock or code T81. 12, Postprocedural septic shock. Additional codes are also required to report other acute organ dysfunctions.
Septic shock with acute organ dysfunction due to group a streptococcus. Septic shock with acute organ dysfunction due to group b streptococcus. Septic shock with acute organ dysfunction due to meningococcal septicemia.
Septic shock with acute organ dysfunction. Septic shock with acute organ dysfunction due to anaerobic septicemia. Septic shock with acute organ dysfunction due to chromobacterium. Septic shock with acute organ dysfunction due to coagulate-negative staphylococcu.
