ICD-10 Code B37.42 – Candidal balanitis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B37.42 – Candidal balanitis
What it is
B37.42 identifies balanitis caused by Candida, a yeast infection affecting the glans penis. Use it when documentation clearly states candidal balanitis or Candida infection of the penis.
Clinical signs
Typical findings include penile redness, irritation, itching, soreness, and sometimes a moist rash or discharge. Clinical features vary; refer to documentation.
When to use this code
Use B37.42 when the provider documents candidal balanitis, Candida balanitis, or a yeast infection of the glans penis. It is appropriate when the diagnosis is confirmed clinically or recorded as the reason for the visit. If the note only says balanitis without a cause, check documentation.
Do not use for
Do not use this code for balanitis from non-Candida causes, such as irritation, bacteria, or unspecified infection. Check documentation if the organism is not named.
Coding tip
Code the fungal cause only when Candida is documented; otherwise, query or use the unspecified balanitis code if supported.
