Code Classification

B37.9 is a billable diagnosis code used to specify a medical diagnosis of candidiasis, unspecified. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

Unspecified diagnosis codes like B37.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Classification

Clinical Information

  • 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.
  • 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).
  • Chronic Mucocutaneous Candidiasis

    mucocutaneous candidiasis that is persistent or long-standing in nature.

Patient Education


Yeast Infections

Candida is the scientific name for yeast. It is a fungus that lives almost everywhere, including in your body. Usually, your immune system keeps yeast under control. If you are sick or taking antibiotics, it can multiply and cause an infection.

Yeast infections affect different parts of the body in different ways:

  • Thrush is a yeast infection that causes white patches in your mouth
  • Candida esophagitis is thrush that spreads to your esophagus, the tube that takes food from your mouth to your stomach. It can make it hard or painful to swallow.
  • Women can get vaginal yeast infections, causing vaginitis
  • Yeast infections of the skin cause itching and rashes
  • Yeast infections in your bloodstream can be life-threatening

Antifungal medicines get rid of yeast infections in most people. If you have a weak immune system, treatment might be more difficult.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
