M72.6: Necrotizing fasciitis

Necrotizing fasciitis, often referred to as "flesh-eating disease," is a rare but serious bacterial skin infection. It spreads rapidly and can quickly become life-threatening. The condition primarily affects the tissue just beneath the skin, known as the fascia, but can also involve the muscle tissue. Symptoms often start with redness, heat, and intense pain in the affected area, and may rapidly progress to include fever, fatigue, and other severe systemic symptoms. Necrotizing fasciitis can be caused by several types of bacteria, most commonly group A Streptococcus. These bacteria can enter the body through injuries such as cuts, burns, insect bites, or surgical wounds. The progression of necrotizing fasciitis can be very quick, and it is critical to diagnose and intervene early to halt the spread of the infection.
