What are Yeast Infection ICD-10-CM Codes?

Yeast infections, primarily caused by the fungus Candida, can affect various body parts. Proper coding for yeast infections is essential for medical documentation, billing, and treatment planning. The ICD-10-CM system provides specific codes for different types of yeast infections, which are classified under superficial mycoses and other superficial mycosis categories.

Here are the most commonly used ICD-10-CM Codes for Yeast Infections:

B37.9 - Candidiasis, unspecified: This is a general code for yeast infections caused by the Candida fungus without specifying the affected area. It applies when candidiasis spreads to multiple mucous membranes or superficial sites.
B37.3 - Candidiasis of vulva and vagina: This code is used when the yeast infection affects the vulva and vagina, often referred to as vagina candidiasis. It is a common cause of itching and discomfort in patients.
B37.0 - Candidal stomatitis: Candidal stomatitis indicates a yeast infection in the mouth or throat, commonly known as oral thrush.

Clinical information

The Candida fungus typically causes yeast infections. These infections fall under the ICD-10-CM classification system and include both acute candidiasis and chronic cases.
These infections can affect various body parts, including the genitals (vagina, vulva), mouth, throat, skin, and other urogenital sites.
Symptoms may include itching, burning, and unusual discharge (in the case of genital yeast infections), along with visible lesions on mucous membranes.
Diagnosis often involves clinical examination and sometimes laboratory tests, particularly when the infection spreads or when neonatal candidiasis or candidal meningitis is suspected.
Treatment options include antifungal medications, creams, or oral medications, depending on the type and location of the infection. Treatment should be tailored to the site involved—whether the infection affects the vulva and vagina, mouth, skin, or other body sites.
