Clinical notes

Code first

This code represents a manifestation of an underlying disease. Coding convention requires the underlying (etiology) code to be sequenced first, with this code listed second.

, if applicable, postprocedural sepsis (T81.44-)
sepsis due to central venous catheter (T80.211-)
streptococcal sepsis during labor (O75.3)
streptococcal sepsis following abortion or ectopic or molar pregnancy (O03.37, O03.87, O04.87, O07.37, O08.82)
streptococcal sepsis following immunization (T88.0-)
streptococcal sepsis following infusion, transfusion or therapeutic injection (T80.22-, T80.29-)

Excludes1 (not coded here)

An Excludes1 note is a pure exclusion: the excluded condition and this code should never be reported together, because the two conditions cannot occur at the same time (e.g. a congenital form vs. an acquired form of the same disease).

neonatal (P36.0-P36.1)
puerperal sepsis (O85)
sepsis due to Streptococcus, group D (A41.81)
