Candidiasis of Skin
Learn about Candidiasis of Skin (C), also known as Candidal Intertrigo, Candidal Paronychia, or Yeast Infection of Skin. This resource provides information for healthcare professionals on diagnosis, treatment, and clinical documentation of cutaneous candidiasis. Find details relevant to medical coding and ICD-10 codes for accurate billing and healthcare records related to skin yeast infections. Explore best practices for managing and documenting Candidiasis cases in various clinical settings.
Fungal skin infection caused by Candida species (like Candida albicans).
Red, itchy rash, often with satellite lesions. May have white patches or pustules. Can affect skin folds, nails, and other areas.
Warm, moist areas like armpits, groin, and between fingers/toes. Diaper rash in infants. Weakened immune system increases risk.

When to use each related code
| Description | When to use |
|---|---|
| Yeast skin infection. | Skin rash with satellite lesions, itching, burning. Intertriginous areas, diaper rash. Rule out other dermatophytes. |
| Yeast infection of the nails. | Nail swelling, redness, pain, separation from the nail bed. Often in those with frequent water exposure. Rule out bacterial paronychia. |
| Yeast infection of mouth/throat. | White patches, redness in mouth, difficulty swallowing. Common in infants, denture wearers, immunocompromised. Rule out leukoplakia. |
Best-practice checklist
- ✓Document affected skin area (e.g., intertriginous, perioral).
- ✓Describe lesion morphology (e.g., erythema, satellite pustules).
- ✓Note presence of predisposing factors (e.g., diabetes, obesity).
- ✓Record KOH prep results if performed.
- ✓Document treatment plan (e.g., topical antifungal, oral antifungal).
Common pitfalls to avoid
Coding candidiasis without specifying the affected skin site (e.g., intertrigo, paronychia) can lead to claim rejections and inaccurate data.
Lack of proper clinical documentation supporting the candidiasis diagnosis may trigger audits and compliance issues.
Failing to capture associated conditions like diabetes, which can increase candidiasis risk, impacts severity and reimbursement.
Best-practice tips
- 01Document skin lesions, location, and type for accurate ICD-10 coding (B37).
- 02Improve CDI with KOH test results to confirm Candida species for B37 diagnoses.
- 03Ensure antifungal Rx aligns with documented Candida type for compliance and optimal care.
- 04Educate patients on hygiene and moisture control to prevent recurrence. Optimize SNOMED CT capture.
- 05For paronychia (L03.0), specify affected digits for precise coding and improved CDI.
Step-by-step checklist
- 1
Confirm skin lesions: erythema, satellite pustules, scaling
- 2
KOH prep/culture positive for Candida species
- 3
Rule out other dermatoses: psoriasis, eczema, contact dermatitis
- 4
Assess risk factors: diabetes, obesity, antibiotic use
Ready-to-paste narrative
Patient presents with clinical manifestations consistent with cutaneous candidiasis (ICD-10-CM B37). Symptoms include erythematous, pruritic rash with satellite lesions located in the [specify location, e.g., intertriginous folds of the groin, axillae, inframammary area; perianal region; nail folds]. Differential diagnosis includes intertrigo, contact dermatitis, psoriasis, and tinea cruris. KOH preparation of skin scrapings reveals pseudohyphae and budding yeast cells, confirming the diagnosis of candidiasis. Risk factors assessed and discussed with the patient include obesity, diabetes mellitus, antibiotic use, immunosuppression, and warm, moist environments. Patient education provided regarding proper hygiene, keeping the affected area dry, and avoiding occlusive clothing. Treatment plan includes topical antifungal therapy with [specify medication, e.g., clotrimazole, miconazole, ketoconazole] cream applied to affected area twice daily for [duration]. Patient advised to follow up if symptoms do not improve within [timeframe] or worsen. Candidal intertrigo, candidal paronychia, and yeast infection of skin were considered as alternate diagnostic terms. Plan to monitor for treatment response and adjust therapy as needed.
Common questions and answers
What are the key clinical features differentiating candidiasis of skin (intertrigo, paronychia) from other dermatological conditions like psoriasis or eczema?+
Candidiasis of skin, encompassing intertrigo and paronychia, presents distinct clinical features that help differentiate it from conditions like psoriasis or eczema. In intertrigo, you'll typically observe beefy-red erythema with satellite pustules and papules in intertriginous areas like skin folds. Paronychia presents as painful swelling and erythema around the nail fold, often with purulent discharge. Unlike the well-demarcated plaques of psoriasis or the dry, lichenified lesions seen in chronic eczema, candidiasis often exhibits maceration and scaling at the borders, with a propensity for moist, warm environments. Microscopic examination with KOH preparation revealing pseudohyphae and budding yeast cells confirms the diagnosis. Explore how different diagnostic tests can aid in accurately distinguishing between these conditions.
How do I choose the most appropriate antifungal treatment strategy for different presentations of cutaneous candidiasis (e.g., mild intertrigo vs. severe paronychia)?+
Choosing the right antifungal treatment for cutaneous candidiasis depends on the severity and location of the infection. For mild intertrigo, topical antifungal creams like nystatin or clotrimazole are often sufficient. However, for severe paronychia with significant inflammation or involvement of the nail matrix, systemic antifungals like fluconazole may be necessary. In cases of recurrent or resistant infections, consider identifying and addressing predisposing factors such as diabetes, immunosuppression, or prolonged antibiotic use. Culture and sensitivity testing can guide therapy in these situations. Learn more about the latest guidelines for managing complicated cutaneous candidiasis.
What patient education points are crucial for preventing recurrence of candidal skin infections, particularly in patients with recurring intertrigo or paronychia?+
Preventing recurrence of candidal skin infections requires comprehensive patient education. Emphasize meticulous hygiene practices, including keeping affected areas clean and dry. Advise patients to avoid tight-fitting clothing and footwear, and to thoroughly dry skin folds after bathing. For patients with recurring intertrigo, consider recommending absorbent powders to minimize moisture. In cases of paronychia, educate patients on proper nail care techniques and the importance of avoiding prolonged water exposure. For individuals with predisposing conditions like diabetes, optimizing glycemic control is paramount. Consider implementing a comprehensive patient education program to empower patients and reduce recurrence rates.
