Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code B37:

Type 1 Excludes

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 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 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.
  • 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.

Information for Patients

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.

Familial candidiasis Familial candidiasis is an inherited tendency to develop infections caused by a type of fungus called Candida. Affected individuals typically have infections of the skin, the nails, and the moist lining of body cavities (mucous membranes). These infections are recurrent and persistent, which means they come back repeatedly and can last a long time. This pattern of infection is called chronic mucocutaneous candidiasis.Candida is commonly present on the skin and on the mucous membranes, and in most people usually causes no health problems. However, certain medications (such as antibiotics and corticosteroids) and other factors can lead to occasional overgrowth of Candida (candidiasis) in the mouth (where it is known as thrush) or in the vagina. These episodes, commonly called yeast infections, usually last only a short time before being cleared by a healthy immune system.Most people with familial candidiasis have chronic or recurrent yeast infections that begin in early childhood. Skin infections lead to a rash with crusty, thickened patches; when these patches occur on the scalp, they can cause loss of hair in the affected area (scarring alopecia). Candidiasis of the nails can result in thick, cracked, and discolored nails and swelling and redness of the surrounding skin. Thrush and gastrointestinal symptoms such as bloating, constipation, or diarrhea are common in affected individuals. Women with familial candidiasis can develop frequent vaginal yeast infections, and infants can have yeast infections on the skin that cause persistent diaper rash.Depending on the genetic change involved in this condition, some affected individuals are at risk for developing systemic candidiasis, a more severe condition in which the infection spreads through the bloodstream to various organs including the brain and the meninges, which are the membranes covering the brain and spinal cord. Systemic candidiasis can be life-threatening.Chronic or recurrent yeast infections can occur in people without familial candidiasis. Some individuals experience recurrent candidiasis as part of a general susceptibility to infections because their immune systems are impaired by a disease such as acquired immune deficiency syndrome (AIDS) or severe combined immunodeficiency (SCID), medications, or other factors. Other individuals have syndromes such as autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) or autosomal dominant hyper-IgE syndrome (AD-HIES) that include a tendency to develop candidiasis along with other signs and symptoms affecting various organs and systems of the body.
