ICD-10 Code B37.8 – Candidiasis of other sites (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code B37.8 – Candidiasis of other sites
What it is
B37.8 identifies candidiasis affecting a site not named by a more specific ICD-10 code. It is used when Candida infection is documented, but the exact location falls into this other-site category.
Clinical signs
Findings depend on the involved site and may include localized redness, irritation, pain, discharge, or mucosal lesions. Clinical features vary; refer to documentation.
When to use this code
Use B37.8 when the provider documents candidiasis at an unspecified or other named body site that is not captured by a more specific candidiasis code. This may apply when the record identifies Candida infection of a site such as the skin or mucosa, but the documentation does not support a more exact code.
Do not use for
Do not use B37.8 if the record supports a more specific candidiasis code, such as oral, esophageal, vulvovaginal, or cutaneous candidiasis. Check documentation when the site or type is unclear.
Coding tip
Choose the most specific candidiasis code available first; use B37.8 only when documentation supports Candida infection but not a more precise site.
