What ICD codes are used for candidemia?

The ICD-10-CM code B37.7 remains the valid and billable code for candidal sepsis, a serious bloodstream infection caused by Candida species. This code falls under the broader chapter of "Certain infectious and parasitic diseases", which includes a range of fungal and parasitic diseases. Specifically, B37.7 is applicable to disseminated candidiasis, and systemic candidiasis.

The B37 category also includes related Candida infections affecting various sites, such as:

B37.0 – Candidal stomatitis (applicable to oral thrush)
B37.1 – Pulmonary candidiasis
B37.2 – Candidiasis of skin and nail
B37.5 – Candidal meningitis
B37.8 – Candidiasis of other sites
B37.9 – Candidiasis, unspecified

However, for systemic cases, B37.7 remains the appropriate code. Proper use of these ICD codes helps ensure accurate diagnosis, effective treatment planning, and correct billing for conditions like invasive candidiasis, candidal endocarditis, and neonatal candidiasis.

Which candidemia ICD codes are billable?

The primary ICD-10-CM code for candidemia, B37.7, is fully billable. Selecting the right codes, including for candidiasis for other sites, helps support precise care delivery and proper reimbursement processes.

Additionally, related conditions such as candidal meningitis, candidiasis unspecified, or yeast infection affecting other organs should be coded based on site and severity, aligning with the most accurate ICD classification.

Clinical information

Candidemia remains one of the most severe forms of infectious and parasitic diseases, with significant morbidity and mortality rates. Clinical signs often include fever, chills, septic shock, and organ dysfunction. High-risk factors include neonatal candidiasis, patients with central venous catheters, prolonged ICU stays, immunosuppression, recent surgery, or broad-spectrum antibiotic use.
The most common causative organism is Candida albicans, but non-albicans species like Candida glabrata, Candida parapsilosis, Candida tropicalis, and the emerging multidrug-resistant Candida auris are of growing concern due to their role in antifungal resistance. In certain cases, unspecified organism may be documented when precise identification has not yet been established.
Guidelines reinforce the importance of timely diagnosis, blood cultures, and antifungal susceptibility testing. Recommended first-line treatment for invasive candidiasis and candidemia includes echinocandins (such as caspofungin, micafungin, anidulafungin, and newer agents like rezafungin), except in cases of candidal meningitis or ocular involvement, where amphotericin B or azoles may be required.
Effective infection control strategies focus on antifungal stewardship, patient hygiene, catheter management, and the prevention of meningococcal and other secondary infections that may complicate the clinical picture.
Understanding the effect of candidemia on patient outcomes and accurately coding these sites of candidiasis ensures better care coordination and reporting across healthcare systems.

Commonly asked questions

Candidemia is typically diagnosed through blood cultures that identify the presence of Candida species in the bloodstream. Additional diagnostic tools, such as PCR-based assays, beta-D-glucan tests, and imaging studies, may be used to confirm the infection and assess for involvement of other organs.

Candidemia can lead to serious complications such as sepsis, organ failure, candidal endocarditis, and candidal meningitis, especially in immunocompromised individuals. Without prompt treatment, it may also spread to the eyes, kidneys, liver, and other vital organs, resulting in long-term health issues or death.

Candidemia prevention focuses on infection control measures such as proper hand hygiene, catheter care, antifungal stewardship, and limiting the use of broad-spectrum antibiotics. Early identification of high-risk patients and reducing unnecessary invasive procedures also help lower the risk of this bloodstream infection.
