ICD-10-CM Code for Candidal Balanitis (Yeast Infection of the Penis)
The ICD-10-CM code for candidal balanitis (yeast infection of the penis) is B37.42.
This code specifically designates candidal balanitis within the ICD-10-CM classification system. Balanitis refers to inflammation of the glans penis, and when caused by Candida species (most commonly Candida albicans), it is coded as B37.42 1.
Clinical Context
Candidal balanitis typically presents with erythematous areas on the glans penis accompanied by pruritus or irritation 1
This condition is the most frequent mycotic infection of the penis, with Candida albicans being the predominant pathogen 2, 3
The infection characteristically affects both the glans and often involves the prepuce (balanoposthitis) 2
Uncircumcised males are at significantly higher risk, with all patients in one large STD clinic study being uncircumcised 2
Associated Risk Factors to Document
Diabetes mellitus is strongly associated with candidal balanitis, with 10.9% of affected men having undiagnosed diabetes 1
Poor genital hygiene, immunocompromised states, and phimosis increase infection risk 1
Sexual transmission is a recognized route, with incidence increasing over time 3
Treatment Overview (for clinical context)
First-line treatment includes topical antifungal agents such as miconazole 2% cream applied twice daily for 7 days 1
For severe or resistant cases, fluconazole 150 mg oral tablet as a single dose may be considered 1
Diabetic patients may require longer treatment courses (7-14 days) due to compromised immune function 1
