L00-L08: Infections of the skin and subcutaneous tissue
L03: Cellulitis
Cellulitis is a group of conditions that involve infection of the skin and its underlying tissues. It can occur anywhere on the body, but it is most common on the legs. It's often caused by bacteria, usually streptococcus or staphylococcus, that get into the body through a break in the skin like a cut, bite, or puncture wound. Cellulitis starts as a small, red, painful patch of skin, which gets larger over time. Other symptoms can include swelling, warmth, and red streaks spreading from the affected area. Some people may also have fever and chills. Without treatment, the infection can spread to the bloodstream or lymph nodes, which can cause serious health problems.
