A41: Other sepsis

Sepsis, listed under the ICD-10 code group range A41, is a severe illness caused by the body's overwhelming response to an infection. With sepsis, the body’s immune system overreacts to an infection, leading to widespread inflammation which can result in organ dysfunction. Sepsis forms part of a larger group of conditions varying from sepsis without complications to severe sepsis and septic shock, which are life-threatening. Sepsis can result from any type of infection: bacterial, viral, fungal, or parasitic, but it's most commonly associated with infections of the lungs, kidneys, skin, or gut. Symptoms often include fever, increased heart rate, increased breathing rate, and confusion. Sepsis severity and progression can depend on the individual’s overall health, the type of organism causing the infection, and the speed at which the condition is diagnosed and treated.
