Code Description

ICD-10 B37.1 is a billable code used to indicate a diagnosis of candidiasis of vulva and vagina.

Key Diagnostic Point:

Candidiasis of the vulva and vagina, commonly known as a yeast infection, is a fungal infection caused primarily by the organism Candida albicans. This condition is characterized by symptoms such as itching, burning, and abnormal vaginal discharge, which may appear thick and white, resembling cottage cheese. The infection can occur in women of all ages and is often associated with factors such as antibiotic use, hormonal changes, diabetes, and immunocompromised states. In immunocompromised patients, such as those with HIV/AIDS or undergoing chemotherapy, the risk of developing candidiasis increases significantly due to a weakened immune response. Diagnosis is typically made through clinical evaluation and may be confirmed by laboratory tests, including culture or microscopic examination of vaginal secretions. Treatment usually involves antifungal medications, which can be administered topically or orally, depending on the severity of the infection. It is crucial for healthcare providers to consider underlying conditions that may predispose patients to recurrent infections and to provide appropriate education on preventive measures.
