Find reliable information for medical professionals and patients seeking to understand this condition.
Yeast infection of the urinary tract, often caused by Candida species.
Frequent urination, burning sensation, cloudy urine, pelvic pain. Asymptomatic cases possible.
Hospital-acquired infections, diabetes, catheter use, immunocompromised patients.
ICD-10 Code Families
Complete code families applicable to B37.49
When to use each related code
| Description | When to use |
|---|---|
| Yeast in urine, often asymptomatic. | Confirmed Candida spp. in urine culture. Consider colonization vs. true infection. |
| Bladder infection, typically bacterial. | Symptoms like dysuria, frequency, urgency. Positive urine culture (E. coli common). |
| Kidney infection, often from ascending UTI. | Flank pain, fever, nausea. Positive urine culture. May follow cystitis. |
Best-practice checklist
- ✓Document yeast species identified in urine culture.
- ✓Specify colony count (CFU/mL) from urine culture.
- ✓Note patient symptoms (dysuria, frequency, urgency).
- ✓Document predisposing factors (diabetes, catheter).
- ✓Record antifungal treatment and response.
Common pitfalls to avoid
Coding candiduria without specifying the Candida species (e.g., albicans, glabrata) can lead to inaccurate reporting and treatment.
Differentiating between asymptomatic candiduria and symptomatic Candida UTI is crucial for appropriate treatment and coding (e.g., N39.0 vs. B37.4).
Distinguishing between complicated and uncomplicated candiduria impacts coding and clinical management, requiring documentation of risk factors.

Ready-to-paste narrative
Patient presents with symptoms suggestive of candiduria, also known as urinary candidiasis or a Candida urinary tract infection. Presenting complaints include dysuria, frequency, urgency, and lower abdominal discomfort. Patient may also report nocturia and suprapubic tenderness. Physical examination may reveal costovertebral angle tenderness or no remarkable findings. Urinalysis demonstrates pyuria and positive yeast on microscopy. Urine culture confirms the presence of Candida species, specifically Candida albicans. Differential diagnosis includes bacterial cystitis, pyelonephritis, and vaginitis. Risk factors for candiduria such as diabetes mellitus, indwelling urinary catheters, recent antibiotic use, and immunocompromised status were assessed. Given the positive urine culture and clinical presentation, a diagnosis of candiduria is made. Treatment plan includes fluconazole, an antifungal medication, prescribed for a duration appropriate to the patient's specific clinical picture. Patient education regarding proper hygiene, catheter care if applicable, and follow-up urine culture to confirm eradication of the infection was provided. ICD-10 code B37.4 Candidiasis of the urinary tract is applicable for medical billing and coding purposes. Patient instructed to return for follow-up evaluation and repeat urinalysis to monitor treatment response.
Common questions and answers
How to differentiate Candiduria from asymptomatic colonization in catheterized patients with suspected Candida UTI?+
Differentiating candiduria from asymptomatic colonization, particularly in catheterized patients, requires a nuanced approach. While the presence of Candida species in urine culture can indicate infection, it's crucial to consider clinical context. Asymptomatic candiduria, especially in those with indwelling catheters, is common and often doesn't require treatment. However, in patients with suggestive symptoms like fever, chills, flank pain, or new-onset urinary symptoms, coupled with positive urine cultures with significant colony counts (typically >10^4 CFU/ml), treatment for Candida UTI is warranted. Explore how to interpret urine culture results in the context of patient presentation for a more accurate diagnosis. Consider implementing strategies to reduce catheter-associated UTIs, including prompt catheter removal when no longer medically necessary, to minimize the risk of candiduria. Learn more about evidence-based guidelines for managing catheter-associated urinary tract infections.
What are the best antifungal treatment options for confirmed Candida glabrata Candiduria, and how do they compare in terms of efficacy and safety?+
Candida glabrata candiduria presents unique treatment challenges due to its intrinsic resistance to fluconazole. Echinocandins, such as caspofungin, micafungin, and anidulafungin, are often considered first-line therapy for Candida glabrata infections. Amphotericin B deoxycholate or liposomal amphotericin B may be used in severe cases or those with echinocandin intolerance. Flucytosine, while typically combined with amphotericin B, is not recommended as monotherapy due to rapid resistance development. The choice of antifungal agent should be guided by patient-specific factors, including drug allergies, renal function, and local resistance patterns. Explore how antifungal susceptibility testing can inform treatment decisions for Candida glabrata. Consider implementing antifungal stewardship programs to optimize treatment efficacy and minimize the development of resistance. Learn more about the latest clinical practice guidelines for the management of complicated urinary tract infections.
When to suspect Candiduria in non-catheterized patients presenting with recurrent UTIs and negative bacterial cultures?+
In non-catheterized patients with recurrent UTIs and persistently negative bacterial cultures, candiduria should be considered, especially in those with predisposing factors such as diabetes mellitus, recent antibiotic use, or immunosuppression. While uncommon, Candida species can cause UTIs in these patients. A thorough clinical evaluation, including a detailed history and physical examination, is essential. Urine microscopy and culture specifically targeting fungal pathogens are crucial for diagnosis. Consider implementing additional diagnostic testing, such as urine fungal PCR, for enhanced sensitivity in suspected cases. Explore how underlying medical conditions can contribute to fungal UTIs in non-catheterized patients. Learn more about strategies for preventing recurrent UTIs, including lifestyle modifications and appropriate antibiotic use.
