ICD-10-CM Code For Candidiasis: Group Overview

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group B37 includes infections caused by Candida species, such as oral thrush, vulvovaginal candidiasis, cutaneous candidiasis, and disseminated candidiasis affecting internal organs. These ICD-10-CM diagnosis codes are used to document the presence and site of Candida infection, capturing disease severity, organ involvement, or clinical complexity relevant to this group. Accurate coding within the ICD-10-CM B37 group supports proper claim adjudication and complete clinical documentation.

ICD-10-CM B37: Candidiasis Overview

The ICD-10-CM B37 code group covers infections caused by Candida species, including mucocutaneous, systemic, and other organ-specific candidiasis. These diagnoses affect integumentary, mucosal, and internal organ systems and range from localized thrush and vulvovaginal infection to disseminated disease. Accurate coding matters for correct claim adjudication and reflects the severity and site of infection for reimbursement and clinical records.

When to Use

Use a code from this group when a clinician documents a Candida infection with a specified site such as oral, vaginal, skin, or disseminated involvement. Select the code that reflects the confirmed organism and the anatomic location or systemic nature of the infection to ensure accurate reporting.

Typical Clinical Scenarios

An otherwise healthy adult presents to urgent care with painful, erythematous swelling of the oral mucosa, white curd-like plaques that scrape off leaving an erythematous base, and difficulty swallowing after a recent course of broad-spectrum antibiotics. The clinician documents acute mucosal yeast infection confirmed by clinical exam and KOH prep, and prescribes topical or systemic antifungal therapy; a candidal infection of the mouth or oropharynx is coded. Typical codes: B37.0, B37.1
A woman of childbearing age reports recurrent vulvovaginal itching, thick white discharge, and dyspareunia over several months despite intermittent treatment; exam and microscopy confirm Candida species with frequent relapses requiring maintenance therapy. This represents a chronic or recurrent mucocutaneous candidiasis of the vulva and vagina and is coded to capture the persistent mucosal infection. Typical codes: B37.3, B37.31, B37.32
A hospitalized patient with central venous catheter and recent broad-spectrum antibiotics develops fever, hypotension, and positive blood cultures for Candida species, consistent with invasive candidemia; antifungal therapy and line management are initiated and the systemic invasive fungal infection is coded. Typical codes: B37.7, B37.5
