N80-N98: Noninflammatory disorders of female genital tract
N90: Other noninflammatory disorders of vulva and perineum
The ICD-10 group N90 refers to a category of health conditions known as Other Noninflammatory Disorders of the Vulva and Perineum. These conditions mainly involve changes and abnormalities in the vulva and perineum (the area between the vaginal opening and the anus in females) that are not due to inflammation. The group includes various conditions such as cysts, abscesses, ulcers, scars, varicose veins, and hypertrophy of vulva and perineum (enlargement or overgrowth of these areas due to an increase in size of its cells). These disorders can occur naturally or can be due to physical trauma, infections, or hormonal imbalances. Despite being noninflammatory, they can still cause distressing symptoms such as discomfort, pain during sexual intercourse, itching, soreness and in some cases, changes to urinary and bowel habits. In many cases, these conditions may worsen over time without appropriate care. Conditions in this group primarily affect the female reproductive and urinary systems.
