  • Candidemia

    a form of invasive candidiasis where species of candida are present in the blood.

  • 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.

  • 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 bloodstream infection resulting from a species of candida.

  • Cordonnier Grade 2 Fungal Complication, Candidemia without Severe Sepsis|Grade 2 Candidemia without Severe Sepsis and without Focus

    any candidemia without severe sepsis and without focus.

  • Cordonnier Grade 2 Fungal Complication, Deep Candida Infection without Candidemia|Grade 2 Deep Candida Infection without Candidemia

    any deep candida infection without candidemia.

  • Cordonnier Grade 3 Fungal Complication, Candidemia with Either Sepsis or Deep Focus|Grade 3 Candidemia with Either Sepsis or Deep Focus

    any candidemia with either sepsis or deep focus.

  • Disseminated Candidiasis

    a fungal infection by any of the candida species in two or more non-contiguous sterile body compartments.

  • Neonatal Candidiasis

    a fungal infection by any of the candida species in a newborn infant up to 28 days old.

  • Fungemia

    a laboratory test result indicating the presence of fungi or yeasts in the blood.

  • Fungemia, CTCAE|Fungemia

    a disorder characterized by the presence of fungus in the blood stream.

  • Grade 2 Fungemia, CTCAE|Grade 2 Fungemia

    moderate symptoms; medical intervention indicated

  • Grade 3 Fungemia, CTCAE|Grade 3 Fungemia

    severe or medically significant but not immediately life-threatening; hospitalization or prolongation of existing hospitalization indicated

  • Invasive Candidiasis

    a fungal infection by any of the candida species in a sterile body compartment.

Patient EducationClinical

Sepsis

Sepsis is your body's overactive and extreme response to an infection. Sepsis is a life-threatening medical emergency. Without quick treatment, it can lead to tissue damage, organ failure, and even death.

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.
