About the B37 Code Range
Candidiasis is an infection caused by a Candida fungus. It usually affects moist areas of the body.
B37 is organized mainly by where the infection occurs, including the mouth, lungs, skin and nails, and vulva and vagina. Vulvar and vaginal candidiasis separates into acute B37.31 and chronic B37.32. Other urogenital sites and other body sites have their own subdivisions, while B37.9 leaves the site unspecified.
