Sepsis due to Hemophilus influenzae

This code identifies a severe systemic inflammatory response syndrome (SIRS) caused specifically by Hemophilus influenzae infection. Sepsis is a life-threatening organ dysfunction resulting from a dysregulated host response to infection.

Apply this code when documentation clearly states a diagnosis of sepsis and laboratory or clinical findings confirm Hemophilus influenzae as the causative organism. This typically occurs in cases of severe bacterial infection leading to organ dysfunction.

• Always sequence sepsis as the principal diagnosis when it meets the definition of principal diagnosis, followed by the localized infection.
• Do not code an additional code for SIRS if sepsis is documented.
• Ensure documentation specifies Hemophilus influenzae as the confirmed pathogen; otherwise, use an unspecified organism code for sepsis.
