Acute candidiasis of vulva and vagina

BILLABLE STATUSYes

Code Description

ICD-10 B37.31 is a billable code used to indicate a diagnosis of acute candidiasis of vulva and vagina.

Key Diagnostic Point:

Acute candidiasis of the vulva and vagina, commonly known as a yeast infection, is a fungal infection caused primarily by the overgrowth of Candida species, particularly Candida albicans. This condition is characterized by inflammation, itching, and discomfort in the vulvar and vaginal areas. Patients may present with symptoms such as a thick, white vaginal discharge resembling cottage cheese, redness, and swelling of the vulva, and dysuria or pain during intercourse. Risk factors for acute candidiasis include antibiotic use, hormonal changes (such as those occurring during pregnancy or with oral contraceptives), uncontrolled diabetes, and immunocompromised states. In immunocompromised patients, such as those with HIV/AIDS or undergoing chemotherapy, the risk of recurrent and severe candidiasis increases significantly. Treatment typically involves antifungal medications, which can be administered topically or orally, depending on the severity of the infection. It is crucial for healthcare providers to accurately diagnose and code this condition to ensure appropriate treatment and management.

  • Understanding the various antifungal treatments and their indications
  • Documenting associated symptoms and clinical findings accurately

Audit Risk Factors

  • Inadequate documentation of symptoms and clinical findings
  • Failure to document underlying conditions that may contribute to candidiasis
  • Incorrect coding of recurrent infections as acute
  • Lack of specificity in treatment documentation
