Candidiasis (B37)

ICD-10 code section B37 covers candidiasis, a group of fungal infections caused by Candida species affecting various body sites. These codes precisely categorize infections ranging from oral thrush (B37.0) to invasive and systemic infections like candidal sepsis (B37.7) and meningitis (B37.5).

This section includes specific codes for common conditions: B37.0 identifies candidal stomatitis, often known as oral thrush or erythema of the mouth's mucous membranes. B37.3 covers vulvovaginal candidiasis, including acute (B37.31) and chronic forms (B37.32), which are frequently encountered in female genital fungal infections. Skin and nail infections such as candidal paronychia fall under B37.2. Pulmonary involvement is classified under B37.1, while urinary tract infections like candidal cystitis and balanitis are found in B37.41 and B37.42, respectively. More severe and disseminated infections, like candidal endocarditis (B37.6) or systemic candidiasis (B37.7), denote invasive disease. The ICD-10 code for candidiasis thus helps clinicians and coders accurately document the infection’s location and severity, assisting in targeted treatment and tracking of fungal infections.

Instructional Notations

Includes

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.

  • candidosis
  • moniliasis

Type 1 Excludes

A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

  • neonatal candidiasis P37.5

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Candida

A genus of yeast-like mitosporic Saccharomycetales fungi characterized by producing yeast cells, mycelia, pseudomycelia, and blastophores. It is commonly part of the normal flora of the skin, mouth, intestinal tract, and vagina, but can cause a variety of infections, including CANDIDIASIS; ONYCHOMYCOSIS; VULVOVAGINAL CANDIDIASIS; and CANDIDIASIS, ORAL (THRUSH).

Candidemia

A form of invasive candidiasis where species of CANDIDA are present in the blood.

Candidiasis

Infection with a fungus of the genus CANDIDA. It is usually a superficial infection of the moist areas of the body and is generally caused by CANDIDA ALBICANS. (Dorland, 27th ed)

Candidiasis, Chronic Mucocutaneous

A clinical syndrome characterized by development, usually in infancy or childhood, of a chronic, often widespread candidiasis of skin, nails, and mucous membranes. It may be secondary to one of the immunodeficiency syndromes, inherited as an autosomal recessive trait, or associated with defects in cell-mediated immunity, endocrine disorders, dental stomatitis, or malignancy.

Candidiasis, Cutaneous

Candidiasis of the skin manifested as eczema-like lesions of the interdigital spaces, perleche, or chronic paronychia. (Dorland, 27th ed)

Candidiasis, Invasive

An important nosocomial fungal infection with species of the genus CANDIDA, most frequently CANDIDA ALBICANS. Invasive candidiasis occurs when candidiasis goes beyond a superficial infection and manifests as CANDIDEMIA, deep tissue infection, or disseminated disease with deep organ involvement.

Candidiasis, Oral

Infection of the mucous membranes of the mouth by a fungus of the genus CANDIDA. (Dorland, 27th ed)

Candidiasis, Vulvovaginal

Infection of the VULVA and VAGINA with a fungus of the genus CANDIDA.

Diaper Rash

A type of irritant dermatitis localized to the area in contact with a diaper and occurring most often as a reaction to prolonged contact with urine, feces, or retained soap or detergent.

Fungemia

The presence of fungi circulating in the blood. Opportunistic fungal sepsis is seen most often in immunosuppressed patients with severe neutropenia or in postoperative patients with intravenous catheters and usually follows prolonged antibiotic therapy.

Intertrigo

A superficial dermatitis occurring on skin surfaces in contact with each other, such as the axillae, neck creases, intergluteal fold, between the toes, etc. Obesity is a predisposing factor. The condition is caused by moisture and friction and is characterized by erythema, maceration, burning, and exudation.
