Streptococcal sepsis (A40)
ICD-10 code section A40 is used specifically for identifying and documenting cases of streptococcal sepsis, a severe bloodstream infection caused by different types of Streptococcus bacteria. This section helps distinguish between infections caused by various groups like Group A, Group B, Streptococcus pneumoniae, and other or unspecified streptococcal organisms.
These codes enable precise classification of streptococcal sepsis to support accurate diagnosis and treatment planning. For example, A40.0 corresponds to sepsis caused by Group A Streptococcus, commonly known as Streptococcus pyogenes, while A40.1 is for sepsis from Group B Streptococcus, such as Streptococcus agalactiae. The code A40.3 covers sepsis due to Streptococcus pneumoniae, often referenced as pneumococcal sepsis. Other less common or unspecified streptococcal sepsis cases fall under A40.8 or A40.9. These codes also encompass related conditions like septic shock linked to acute organ dysfunction caused by these bacteria. Using the correct ICD-10 code for streptococcal sepsis ensures clear communication in clinical and billing contexts and helps track the specific bacterial cause of septicemia.
Instructional Notations
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.
